L. Luhman, Lucia Adame, Paola D'Alessio, Nuria Calvet, Lee Hartmann, S. T. Megeath, and G. G. Fazio Comments: 5 pages, accepted to Astrophysical Journal Letters \\ Using the Hubble Space Telescope, the 4 m Blanco telescope at the Cerro Tololo Inter-American Observatory, and the Spitzer Space Telescope, we have performed deep imaging from 0.8 to 8 um of the southern subcluster in the Chamaeleon I star-forming region. In these data, we have discovered an object, Cha 110913-773444, whose colors and magnitudes are indicative of a very low-mass brown dwarf with a circumstellar disk. In a near-infrared spectrum of this source obtained with the Gemini Near-Infrared Spectrograph, the presence of strong steam absorption confirms its late-type nature (>=M9.5) while the shapes of the H- and K-band continua and the strengths of the Na I and K I lines demonstrate that it is a young, pre-main-sequence object rather than a field dwarf. A comparison of the bolometric luminosity of Cha 110913-773444 to the luminosities predicted by the evolutionary models of Chabrier and Baraffe and Burrows and coworkers indicates a mass of 8+7/-3 M_Jup, placing it fully within the mass range observed for extrasolar planetary companions (M<=15 M_Jup). The spectral energy distribution of this object exhibits mid-infrared excess emission at >5 um, which we have successfully modeled in terms of an irradiated viscous accretion disk with M'<=10e-12 M_sun/year. Cha 110913-773444 is now the least massive brown dwarf observed to have a circumstellar disk, and indeed is one of the least massive free-floating objects found to date. These results demonstrate that the raw materials for planet formation exist around free-floating planetary-mass bodies. \\ ( http://arXiv.org/abs/astro-ph/0511807 , 27kb) From owner-public@setileague.org Thu Dec 1 07:14:07 2005 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: * X-Spam-Status: No, score=1.3 required=5.5 tests=MSGID_FROM_MTA_HEADER, RCVD_IN_BL_SPAMCOP_NET autolearn=no version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id jB1FE6mU021164 for ; Thu, 1 Dec 2005 07:14:06 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id JAA29379 for public-list; Thu, 1 Dec 2005 09:59:54 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f24.bay114.hotmail.com [65.54.169.34]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id JAA29375; Thu, 1 Dec 2005 09:59:51 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Thu, 1 Dec 2005 06:59:18 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Thu, 01 Dec 2005 14:59:17 GMT X-Originating-IP: [24.39.94.195] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: Interview with Jon Lomberg on the Voyager Interstellar Record Date: Thu, 01 Dec 2005 09:59:17 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 01 Dec 2005 14:59:18.0162 (UTC) FILETIME=[CDAD1F20:01C5F687] Sender: owner-public@setileague.org Precedence: bulk Voyager - A message from Earth Saturday 19 November 2005 Summary Jon Lomberg is an artist who could be called portrait painter to the cosmos.

The burst of meteors radiated from a direction on the border of the constellations Draco and Camelopardalis, and the new shower is called the October Camelopardalids. The meteors were caused by dust ejected by an Intermediate Long-Period comet during its previous return to the Sun, and the detection of the comet's dust trail implies that the comet itself could wander into Earth's path, if so directed by the gravitational pull of the planets. The comet itself has not yet been discovered and is likely to return to Earth's vicinity only once every 200 - 10,000 years. Chances are very small that Earth will be at the intersection point at the time of the return, hence, there is no immediate concern. The dust, however, is forensic evidence that may provide more insight into the nature of this new comet when the meteor shower is seen again in the future. 2005 OCTOBER 5 OUTBURST OF OCTOBER CAMELOPARDALIDS Peter Jenniskens, Jarmo Moilanen, Esko Lyytinen, Ilkka Yrjölä, Jeff Brower http://www.seti.org/atf/cf/{B0D4BC0E-D59B-4CD0-9E79-113953A58644}/WGNreport.pdf Abstract of the report in WGN: the Journal of the International Meteor Organization "Jarmo Moilanen (Finland), detected twelve meteors from a compact geocentric radiant at R. A. = 164.1 ± 2.0º, Decl. = +78.9 ± 0.5º, on the border of Draco and Camelopardalis, in the evening of October 5, 2005. The differential mass distribution index was a low s = 1.4 ± 0.2 (+0 to -6 magnitude). The new shower was confirmed by Esko Lyytinen (2 meteors, early period only, located at 25.00 E; +60.25 N) and Ilkka Yrjölä (4 meteors: 26.4 E, +60.9 N) at nearby locations, and by Sirko Molau in Germany (7 meteors). Esko Lyytinen calculated an apparent speed of Vg = 47.3 ± 0.5 km/s from one two-station meteor, close to the parabolic limit. We conclude that the event was caused by the 1-revolution dust trail of a yet unidentified potentially Earth-threatening (Halley-type or) Intermediate Long-Period comet with orbital elements similar to those of the meteoroids: Epoch = 2005 October 05, a = Inf. (15 - Inf.) AU, q = 0.993±0.001 AU, w = 170.5±1º, W = 192.59±0.04º , and i = 79.3±0.5º (J2000.0)."

Kaltenegger, K. Jucks, W.Traub Comments: for high resolution images see http://cfa-www.harvard.edu/~lkaltenegger Journal-ref: CUP, IAUC 200 proceedings, 2005 \\ The search for life on extrasolar planets is based on the assumption that one can screen extrasolar planets for habitability spectroscopically. The first space born instruments able to detect as well as characterize extrasolar planets, Darwin and terrestrial planet finder (TPF-I and TPF-C) are scheduled to launch before the end of the next decade. The composition of the planetary surface, atmosphere, and its temperature-pressure profile influence a detectable spectroscopic signal considerably. For future space-based missions it will be crucial to know this influence to interpret the observed signals and detect signatures of life in remotely observed atmospheres. We give an overview of biomarkers in the visible and IR range, corresponding to the TPF-C and TPF-I/DARWIN concepts, respectively. We also give an overview of the evolution of biomarkers over time and its implication for the search for life on extrasolar Earth-like planets. We show that atmospheric features on Earth can provide clues of biological activities for at least 2 billion years. \\ ( http://arXiv.org/abs/astro-ph/0512053 , 391kb) From owner-public@setileague.org Mon Dec 5 08:55:47 2005 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.5 tests=HTML_MESSAGE autolearn=failed version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id jB5Gtj9f012384 for ; Mon, 5 Dec 2005 08:55:46 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id LAA00681 for public-list; Mon, 5 Dec 2005 11:49:11 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from host224.ipowerweb.com ([66.235.220.224]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id LAA00674 for ; Mon, 5 Dec 2005 11:49:09 -0500 (EST) Received: from cpe-66-27-116-71.san.res.rr.com ([66.27.116.71] helo=Zeke) by host224.ipowerweb.com with smtp (Exim 4.43) id 1EjJVu-00057t-8C for public@seti1.setileague.org; Mon, 05 Dec 2005 08:48:30 -0800 Message-ID: <001801c5f9bb$bc139e10$887ba8c0@Zeke> From: "James Brown" To: "SETI League Public" Subject: SETI public: How UFO's are spotted.

There's a lot hiding in the universe's dark corners. Interstellar dust clouds and inky stretches of deep space can appear dull to ordinary telescopes. But to a car-size telescope 26 million miles (42 million kilometers) from Earth, they are alive with light—infrared light, or heat rays. Since its launch in August 2003, says Robert Kennicutt, an astronomer at the University of Arizona, NASA's Spitzer Space Telescope "has opened up half the universe to us." In the process, it has exposed cosmic birthplaces. Stars take shape in clouds of gas and dust, and planets emerge in disks of debris around new stars. Early galaxies are also swathed in dust. Little visible light gets out, but these objects still emit heat—and infrared. http://www7.nationalgeographic.com/ngm/0512/feature5/index.html From owner-public@setileague.org Mon Dec 5 16:25:45 2005 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.5 tests=HTML_MESSAGE autolearn=failed version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id jB60Pjvn014964 for ; Mon, 5 Dec 2005 16:25:45 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id TAA12962 for public-list; Mon, 5 Dec 2005 19:19:55 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from host224.ipowerweb.com ([66.235.220.224]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id TAA12954 for ; Mon, 5 Dec 2005 19:19:50 -0500 (EST) Received: from cpe-66-27-116-71.san.res.rr.com ([66.27.116.71] helo=Zeke) by host224.ipowerweb.com with smtp (Exim 4.43) id 1EjQY1-0001DR-QG; Mon, 05 Dec 2005 16:19:09 -0800 Message-ID: <001001c5f9fa$b215cac0$887ba8c0@Zeke> From: "James Brown" To: "SETI League Public" , "SETI League Argus" Subject: SETI public: Icom R7000 Controller Date: Mon, 5 Dec 2005 16:19:16 -0800 MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="----=_NextPart_000_000D_01C5F9B7.A3553950" X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 6.00.2800.1506 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1506 X-AntiAbuse: This header was added to track abuse, please include it with any abuse report X-AntiAbuse: Primary Hostname - host224.ipowerweb.com X-AntiAbuse: Original Domain - seti1.setileague.org X-AntiAbuse: Originator/Caller UID/GID - [47 12] / [47 12] X-AntiAbuse: Sender Address Domain - seti.net X-Source: X-Source-Args: X-Source-Dir: Sender: owner-public@setileague.org Precedence: bulk This is a multi-part message in MIME format. ------=_NextPart_000_000D_01C5F9B7.A3553950 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable As part of the work to integrate my R7000 into SETI net I had to = construct the basic control software.

E. Kokubo, H. Arakida, and T. Yamamoto. Tokyo, Japan, 2003 \\ Recent observations (Burnes2002,Veillet2002,Margot2002a) have revealed an unexpectedly high binary fraction among the Trans-Neptunian Objects (TNOs) that populate the Kuiper Belt. The TNO binaries are strikingly different from asteroid binaries in four respects (Veillet2002): their frequency is an order of magnitude larger, the mass ratio of their components is closer to unity, and their orbits are wider and highly eccentric. Two explanations have been proposed for their formation, one assuming large numbers of massive bodies (Weidenschilling2002), and one assuming large numbers of light bodies (Goldreich2002). We argue that both assumptions are unwarranted, and we show how TNO binaries can be produced from a modest number of intermediate-mass bodies of the type predicted by the gravitational instability theory for the formation of planetesimals (Goldreich and Ward1973). We start with a TNO binary population similar to the asteroid binary population, but subsequently modified by three-body exchange reactions, a process that is far more efficient in the Kuiper belt, because of the much smaller tidal perturbations by the Sun. Our mechanism can naturally account for all four characteristics that distinguish TNO binaries from main-belt asteroid binaries. \\ ( http://arXiv.org/abs/astro-ph/0512075 , 148kb) From owner-public@setileague.org Tue Dec 6 11:16:34 2005 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: * X-Spam-Status: No, score=1.3 required=5.5 tests=MSGID_FROM_MTA_HEADER, RCVD_IN_BL_SPAMCOP_NET autolearn=no version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id jB6JGXqZ020997 for ; Tue, 6 Dec 2005 11:16:34 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id OAA13130 for public-list; Tue, 6 Dec 2005 14:11:58 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f30.bay114.hotmail.com [65.54.169.40]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id OAA13126; Tue, 6 Dec 2005 14:11:56 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Tue, 6 Dec 2005 11:11:24 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Tue, 06 Dec 2005 19:11:24 GMT X-Originating-IP: [24.39.94.195] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: The Fate of the Accelerating Universe Date: Tue, 06 Dec 2005 14:11:24 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 06 Dec 2005 19:11:24.0849 (UTC) FILETIME=[D9F32210:01C5FA98] Sender: owner-public@setileague.org Precedence: bulk Paper: astro-ph/0106387 replaced with revised version Sat, 3 Dec 2005 17:23:28 GMT (248kb) Title: The Fate of the Accelerating Universe Authors: Je-An Gu, W-Y. P. Hwang Comments: 16 pages, 5 figures, LaTeX The presently accelerating universe may keep accelerating forever, eventually run into the event horizon problem, and thus be in conflict with the superstring idea. In the other way around, the current accelerating phase as well as the fate of the universe may be swayed by a negative cosmological constant, which dictates a big crunch. Based on the current observational data, in this paper we investigate how large the magnitude of a negative cosmological constant is allowed to be. In addition, for distinguishing the sign of the cosmological constant via observations, we point out that a measure of the evolution of the dark energy equation of state may be a good discriminator. Hopefully future observations will provide much more detailed information about dark energy and thereby indicates the sign of the cosmological constant as well as the fate of the presently accelerating universe. \\ ( http://arXiv.org/abs/astro-ph/0106387 , 248kb) From owner-public@setileague.org Tue Dec 6 11:18:07 2005 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: * X-Spam-Status: No, score=1.3 required=5.5 tests=MSGID_FROM_MTA_HEADER, RCVD_IN_BL_SPAMCOP_NET autolearn=no version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id jB6JI6ih021016 for ; Tue, 6 Dec 2005 11:18:07 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id OAA13018 for public-list; Tue, 6 Dec 2005 14:08:09 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f16.bay114.hotmail.com [65.54.169.26]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id OAA12999; Tue, 6 Dec 2005 14:08:05 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Tue, 6 Dec 2005 11:07:34 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Tue, 06 Dec 2005 19:07:33 GMT X-Originating-IP: [24.39.94.195] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: Objective Subclass Determination of Sloan Digital Sky Survey Unknown Spectral Ob Date: Tue, 06 Dec 2005 14:07:33 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 06 Dec 2005 19:07:34.0194 (UTC) FILETIME=[5077F920:01C5FA98] Sender: owner-public@setileague.org Precedence: bulk Paper: astro-ph/0512119 Date: Mon, 5 Dec 2005 18:34:27 GMT (419kb) Title: Objective Subclass Determination of Sloan Digital Sky Survey Unknown Spectral Objects Authors: David Bazell, David J. Miller, Mark SubbaRao Comments: 19 pages; 5 figures; submitted to Ap. J \\ We analyze a portion of the SDSS photometric catalog, consisting of approximately 10,000 objects that have been spectroscopically classified into stars, galaxies, QSOs, late-type stars and unknown objects, in order to investigate the existence and nature of subclasses of the unknown objects. We use a modified mixture modeling approach that makes use of both labeled and unlabeled data and performs class discovery on the data set. This technique discovers putative novel classes by identifying compact clusters that largely contain objects from the unknown class of objects. These clusters are of possible scientific interest because they represent structured groups of outliers, relative to the known object classes. We identify two such well defined subclasses of the unknown object class. One subclass contains 58% unknown objects, 40% stars, and 2% galaxies, QSOs, and late-type stars.

We discuss possible interpretations of these subclasses while also noting some caution must be applied to purely color-based object classifications. As a side benefit of this limited study we also find two distinct classes, consisting largely of galaxies, that coincide with the recently discussed bimodal galaxy color distribution. \\ ( http://arXiv.org/abs/astro-ph/0512119 , 419kb) From owner-public@setileague.org Wed Dec 7 08:07:53 2005 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: * X-Spam-Status: No, score=1.3 required=5.5 tests=MSGID_FROM_MTA_HEADER, RCVD_IN_BL_SPAMCOP_NET autolearn=no version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id jB7G7q3T030096 for ; Wed, 7 Dec 2005 08:07:53 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id KAA16243 for public-list; Wed, 7 Dec 2005 10:55:35 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f21.bay114.hotmail.com [65.54.169.31]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id KAA16239; Wed, 7 Dec 2005 10:55:32 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Wed, 7 Dec 2005 07:54:53 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Wed, 07 Dec 2005 15:54:53 GMT X-Originating-IP: [24.39.94.195] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: Message in the Sky Date: Wed, 07 Dec 2005 10:54:53 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 07 Dec 2005 15:54:53.0936 (UTC) FILETIME=[906E5700:01C5FB46] Sender: owner-public@setileague.org Precedence: bulk Paper (*cross-listing*): physics/0510102 replaced with revised version Tue, 6 Dec 2005 06:20:04 GMT (7kb) Title: Message in the Sky Authors: S.

Zee Comments: 3 pages, revtex Subj-class: Popular Physics We argue that the cosmic microwave background (CMB) provides a stupendous opportunity for the Creator of universe our (assuming one exists) to have sent a message to its occupants, using known physics. Our work does not support the Intelligent Design movement in any way whatsoever, but asks, and attempts to answer, the entirely scientific question of what the medium and message might be IF there was actually a message. The medium for the message is unique. We elaborate on this observation, noting that it requires only careful adjustment of the fundamental Lagrangian, but no direct intervention in the subsequent evolution of the universe. \\ ( http://arXiv.org/abs/physics/0510102 , 7kb) From owner-public@setileague.org Wed Dec 7 08:10:01 2005 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: * X-Spam-Status: No, score=1.3 required=5.5 tests=MSGID_FROM_MTA_HEADER, RCVD_IN_BL_SPAMCOP_NET autolearn=no version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id jB7GA05K030138 for ; Wed, 7 Dec 2005 08:10:01 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id KAA16336 for public-list; Wed, 7 Dec 2005 10:58:42 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f26.bay114.hotmail.com [65.54.169.36]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id KAA16331; Wed, 7 Dec 2005 10:58:38 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Wed, 7 Dec 2005 07:58:05 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Wed, 07 Dec 2005 15:58:04 GMT X-Originating-IP: [24.39.94.195] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: A bunch of recent relevant papers Date: Wed, 07 Dec 2005 10:58:04 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 07 Dec 2005 15:58:05.0648 (UTC) FILETIME=[02B34500:01C5FB47] Sender: owner-public@setileague.org Precedence: bulk Paper: astro-ph/0512091 Date: Mon, 5 Dec 2005 09:41:44 GMT (49kb) Title: Birth and fate of hot-Neptune planets Authors: I. Baraffe, Y. Alibert, G. Chabrier, W. Benz Comments: 4 figures, accepted for publication in Astronomy and Astrophysics \\ This paper presents a consistent description of the formation and the subsequent evolution of gaseous planets, with special attention to short-period, low-mass hot-Neptune planets characteristic of $\mu$ Ara-like systems. We show that core accretion including migration and disk evolution and subsequent evolution taking into account irradiation and evaporation provide a viable formation mechanism for this type of strongly irradiated light planets. At an orbital distance $a \simeq$ 0.1 AU, this revised core accretion model leads to the formation of planets with total masses ranging from $\sim$ 14 $\mearth$ (0.044 $\mjup$) to $\sim$ 400 $\mearth$ (1.25 $\mjup$). The newly born planets have a dense core of $\sim$ 6 $\mearth$, independent of the total mass, and heavy element enrichments in the envelope, $M_{\rm Z,env}/M_{\rm env} $, varying from 10% to 80% from the largest to the smallest planets. We examine the dependence of the evolution of the born planet on the evaporation rate due to the incident XUV stellar flux. In order to reach a $\mu$ Ara-like mass ($\sim$ 14 $\mearth$) after $\sim $ 1 Gyr, the initial planet mass must range from 166 $\mearth$ ($\sim$ 0.52 $\mjup$) to about 20 $\mearth$, for evaporation rates varying by 2 orders of magnitude, corresponding to 90% to 20% mass loss during evolution. The presence of a core and heavy elements in the envelope affects appreciably the structure and the evolution of the planet and yields $\sim 8%-9%$ difference in radius compared to coreless objects of solar composition for Saturn-mass planets. These combinations of evaporation rates and internal compositions translate into different detection probabilities, and thus different statistical distributions for hot-Neptunes and hot-Jupiters. \\ ( http://arXiv.org/abs/astro-ph/0512091 , 49kb) Paper: astro-ph/0512092 Date: Mon, 5 Dec 2005 09:50:13 GMT (523kb) Title: Analysis of ground-based differential imager performance Authors: A.

Our analysis is providing critical specifications for future instruments mostly in terms of phase aberrations but also regarding alignments of the instrument optics or offset pointing on the coronagraph. It is found that Planet Finder projects on 8m class telescopes can be successful at detecting Extrasolar Giant Planets providing phase aberrations, alignments and pointing are accurately controlled. The situation is more pessimistic for the detection of terrestrial planets with Extremely Large Telescopes for which phase aberrations must be lowered at a very challenging level. \\ ( http://arXiv.org/abs/astro-ph/0512092 , 523kb) Paper: astro-ph/0512105 Date: Mon, 5 Dec 2005 13:30:00 GMT (96kb) Title: Multiplicity-Study of Exoplanet Host Stars Authors: M.

Data are analyzed for 775 stars selected from the Grid Giant Star Survey spanning a wide range of effective temperatures (Teff), gravities and metallicities. The spectra are used to determine these stellar parameters and to monitor radial velocity (RV) variability at the 100 m/s level. The degree of RV variation measured for 489 stars observed two or more times is explored as a function of the inferred stellar parameters. The percentage of radial velocity unstable stars is found to be very high -- about 2/3 of our sample. It is found that the fraction of RV-stable red giants (at the 100 m/s level) is higher among stars with Teff \sim 4500 K, corresponding to the calibration-independent range of infrared colors 0.59 < (J-K_s)_0 < 0.73. A higher percentage of RV-stable stars is found if the additional constraints of surface gravity and metallicity ranges 2.3< log g < 3.2 and -0.5 < [Fe/H] < -0.1, respectively, are applied. Selection of stars based on only photometric values of effective temperature (4300 K < Teff < 4700 K) is a simple and effective way to increase the fraction of RV-stable stars. The optimal selection of RV-stable stars, especially in the case when the Washington photometry is unavailable, can rely effectively on 2MASS colors constraint 0.59 < (J-K_s)_0 < 0.73. These results have important ramifications for the use of giant stars as astrometric references for the SIM PlanetQuest. \\ ( http://arXiv.org/abs/astro-ph/0512108 , 116kb) Paper: astro-ph/0512150 Date: Tue, 6 Dec 2005 14:47:01 GMT (758kb) Title: Dynamic tides in rotating objects: orbital circularisation of extra solar planets for realistic planet models Authors: P. B. Ivanov, J. C. B. Papaloizou Comments: Submitted to MNRAS, resolution of several figures has been reduced \\ (abbreviated) We consider the problem of the tidal capture or circularisation from large eccentricity of a uniformly rotating object. We extend the self-adjoint formalism introduced in Papaloizou & Ivanov 2005 (PI) to derive general expressions for the energy and angular momentum transfered when the planet or a star passes through periastron in a parabolic or highly eccentric orbit around a central mass, without making a low frequency approximation as was done in PI. We show how these can be adapted to the low frequency limit in which only inertial modes contribute to the energy and angular momentum transfer. We calculate the inertial mode eigenspectrum for planet models of one and five Jupiter masses $M_J,$ without a solid core, with different radii corresponding to different ages. We consider the multi-passage problem when there is no dissipation finding that stochastic instability resulting in the stochastic gain of inertial mode energy over many periastron passages occurs under similar conditions to those already found for the $f$ modes. We apply our calculations to the problem of the tidal circularisation of the orbits of the extra solar planets in a state of pseudo synchronisation, and find that inertial mode excitation dominates the tidal interaction for $1 M_J$ planets that start with semi- major axes less than $10 AU$ and end up on circular orbits with final period in the 4-6 day range. It is potentially able to account for initial circularisation up to a final 6 day period within a few $Gyr$ But in the case of $5M_J$ oscillation modes excited in the star are more important. \\ ( http://arXiv.org/abs/astro-ph/0512150 , 766kb) From owner-public@setileague.org Wed Dec 7 08:11:19 2005 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: * X-Spam-Status: No, score=1.3 required=5.5 tests=MSGID_FROM_MTA_HEADER, RCVD_IN_BL_SPAMCOP_NET autolearn=no version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id jB7GBIaf030172 for ; Wed, 7 Dec 2005 08:11:18 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id LAA16513 for public-list; Wed, 7 Dec 2005 11:04:41 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f16.bay114.hotmail.com [65.54.169.26]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id LAA16499; Wed, 7 Dec 2005 11:04:38 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Wed, 7 Dec 2005 08:04:06 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Wed, 07 Dec 2005 16:04:06 GMT X-Originating-IP: [24.39.94.195] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: Giant black holes wandering the Universe Date: Wed, 07 Dec 2005 11:04:06 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 07 Dec 2005 16:04:06.0868 (UTC) FILETIME=[DA011140:01C5FB47] Sender: owner-public@setileague.org Precedence: bulk Paper: astro-ph/0512073 Date: Fri, 2 Dec 2005 21:46:44 GMT (309kb) Title: The Effect of Gravitational Recoil on Black Holes Forming in a Hierarchical Universe Authors: N. I. Libeskind, S. Cole, C. S. Frenk, J. C. Helly Comments: 12 pages, 7 figures, Submitted to MNRAS \\ Galactic bulges are known to harbour central black holes whose mass is tightly correlated with the stellar mass and velocity dispersion of the bulge. In a hierarchical universe, mergers of subgalactic units are accompanied by the amalgamation of bulges and the likely coalescence of galactocentric black holes. In these mergers, the beaming of gravitational radiation during the plunge phase of the black hole collision can impart a linear momentum kick or ``gravitational recoil'' to the remnant. If large enough, this kick will eject the remnant from the galaxy and populate intergalactic space with wandering black holes. Using a semi-analytic model of galaxy formation, we investigate the effect of black hole ejections on the scatter in the relation between black hole and bulge mass. We find that although not the dominant source of the measured scatter, they do make a significant contribution and may be used to set a constraint, v_kick<500 km/s, on the typical kick velocity, in agreement with values found from general relativistic calculations. Even for the more modest kick velocities implied by these calculations, we find that a substantial number of central black holes are ejected from the progenitors of present day galaxies, giving rise to a population of wandering intrahalo and intergalactic black holes whose distribution we investigate in high-resolution N-body simulations of Milk-Way mass halos. We find that intergalactic black holes make up only ~2-3% of the total galactic black hole mass but, within a halo, wandering black holes can contribute up to about half of the total black hole mass orbiting the central galaxy. Intrahalo black holes offer a natural explanation for the compact X-ray sources often seen near the centres of galaxies and for the hyperluminous non-central X-ray source in M82. \\ ( http://arXiv.org/abs/astro-ph/0512073 , 309kb) Paper: astro-ph/0512123 Date: Mon, 5 Dec 2005 20:41:27 GMT (913kb) Title: The Role of Primordial Kicks on Black Hole Merger Rates Authors: Miroslav Micic, Tom Abel and Steinn Sigurdsson Comments: 12 pages, 9 figures, submitted to MNRAS Journal-ref: proceedings of 22nd Texas Symposium on Relativistic Astrophysics, Stanford University, December 13-17, 2004 \\ Primordial stars are likely to be very massive $\geq30\Msun$, form in isolation, and will likely leave black holes as remnants in the centers of their host dark matter halos in the mass range $10^{6}-10^{10}\Ms$. Such early black holes, at redshifts z$\gtsim10$, could be the seed black holes for the many supermassive black holes found in galaxies in the local universe. If they exist, their mergers with nearby supermassive black holes may be a prime signal for long wavelength gravitational wave detectors. We simulate formation of black holes in the center of high redshift dark matter halos and explore implications of initial natal kick velocities conjectured by some formation models. The central concentration of early black holes in present day galaxies is reduced if they are born even with moderate kicks of tens of km/s. The modest kicks allow the black holes to leave their parent halo, which consequently leads to dynamical friction being less effective on the lower mass black holes as compared to those still embedded in their parent halos. Therefore, merger rates may be reduced by more than an order of magnitude. Using analytical and illustrative cosmological N--body simulations we quantify the role of natal kicks of black holes formed from massive metal free stars on their merger rates with supermassive black holes in present day galaxies. Our results also apply to black holes ejected by the gravitational slingshot mechanism. \\ ( http://arXiv.org/abs/astro-ph/0512123 , 913kb) Paper: astro-ph/0511397 replaced with revised version Mon, 5 Dec 2005 12:21:20 GMT (464kb) Title: The ecology of star clusters and intermediate mass black holes in the Galactic bulge Authors: Simon Portegies Zwart (UvA), Holger Baumgardt (Bonn), Stephen L. W. McMillan (Drexel), Junichiro Makino (tokyo), Piet Hut (IAS), Toshi Ebisuzaki (RIKEN) Comments: 26 pages, ApJ in press. Old title: The Galactic center welcomes black hole immigrants We simulate the inner 100pc of the Milky-Way Galaxy to study the formation and evolution of the population of star clusters and intermediate mass black holes. For this study we perform extensive direct N-body simulations of the star clusters which reside in the bulge, and of the inner few tenth of parsecs of the super massive black hole in the Galactic center. In our N-body simulations the dynamical friction of the star cluster in the tidal field of the bulge are taken into account via (semi)analytic soluations. The N-body calculations are used to calibrate a (semi)analytic model of the formation and evolution of the bulge. We find that about 10% of the clusters born within 100pc of the Galactic center undergo core collapse during their inward migration and form intermediate-mass black holes (IMBHs) via runaway stellar merging. After the clusters dissolve, these IMBHs continue their inward drift, carrying a few of the most massive stars with them. We predict that region within about 10 parsec of the SMBH is populated by about 50IMBHs of some 1000Msun. Several of these are expected to be accompanied still by some of the most massive stars from the star cluster. We also find that within a few milliparsec of the SMBH there is a steady population of several IMBHs. This population drives the merger rate between IMBHs and the SMBH at a rate of about one per 10Myr, sufficient to build the accumulate majority of mass of the SMBH. Mergers of IMBHs with SMBHs throughout the universe are detectable by LISA, at a rate of about two per week. \\ ( http://arXiv.org/abs/astro-ph/0511397 , 464kb) From owner-public@setileague.org Wed Dec 7 14:11:43 2005 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: X-Spam-Status: No, score=0.5 required=5.5 tests=PLING_PLING autolearn=no version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id jB7MBgE3007815 for ; Wed, 7 Dec 2005 14:11:42 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id RAA26017 for public-list; Wed, 7 Dec 2005 17:06:52 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from krypton2.melitacable.com (smtp.onvol.net [212.56.128.131]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id RAA25992; Wed, 7 Dec 2005 17:06:37 -0500 (EST) Received: from vol.net.mt (ppp-130-15-dial3.as.vol.net.mt [212.56.130.15]) by krypton2.melitacable.com (8.12.11/8.12.11) with ESMTP id jB7M52uq011264; Wed, 7 Dec 2005 23:05:03 +0100 (CET) Message-ID: <43975BB5.C0A10918@vol.net.mt> Date: Wed, 07 Dec 2005 23:01:30 +0100 From: Alex Michael Bonnici X-Mailer: Mozilla 4.75 [en] (Win95; U) X-Accept-Language: en MIME-Version: 1.0 To: FPSpace , setipublic , BioAstro Subject: SETI public: Tunguska, Gervase, and the link the Beta Taurids and Megalithic Temples!!!!

     I never really believed in Velikovsky's idea that plasma proto-planets were ejected by Jupiter and wreck havoc with the Solar System. But I always suspected that a very rich meteor shower may account for many of the myths and legends that spoke of the wrath of the Gods and fire raining from the sky. The legend of Gilgamesh,  talks of "the Seven Judges of Hell", who raised their torches, lighting the land with flame, and a storm that turned day into night, "smashed the land like a cup", and flooded the area. Four  years ago an article in the Sunday Telegraph entitled "METEOR CLUE TO END OF MIDDLE EAST CIVILISATIONS By Robert Matthews, Science Correspondent dated 4 November 2001  mentioned that scientists have found the first evidence that a devastating meteor impact in the Middle East might have triggered the mysterious collapse of civilisations more than 4,000 years ago.

In this paper we present the results for NGC 2158, an intermediate age, populous cluster. We have monitored the cluster for over 260 hours, spread over 59 nights. We have detected one candidate transiting low luminosity object, with eclipse depth of 3.7% in the R-band. If the host star is a member of the cluster, the eclipse depth is consistent with a 1.7 R_J object. Cluster membership of the host is supported by its location on the cluster main sequence (MS) and its close proximity to the cluster center (2'). We have discovered two other stars exhibiting low-amplitude (4-5%) transits, V64 and V70, but they are most likely blends or field stars. Given the photometric precision and temporal coverage of our observations, and current best estimates for the frequency and radii of short-period planets, the expected number of detectable transiting planets in our sample is 0.13. We have observed four outbursts for the candidate cataclysmic variable V57. We have discovered 40 new variable stars in the cluster, bringing the total number of identified variables to 97, and present for them high precision light curves, spanning 13 months. \\ ( http://arXiv.org/abs/astro-ph/0512198 , 931kb) Paper: astro-ph/0501145 replaced with revised version Wed, 7 Dec 2005 20:15:56 GMT (327kb) Title: Planets in Stellar Clusters Extensive Search.

Authors: Max Tegmark (MIT), Nick Bostrom (Oxford) Comments: 3 pages, 1 fig \\ Numerous Earth-destroying doomsday scenarios have recently been analyzed, including breakdown of a metastable vacuum state and planetary destruction triggered by a "strangelet" or microscopic black hole. We point out that many previous bounds on their frequency give a false sense of security: one cannot infer that such events are rare from the the fact that Earth has survived for so long, because observers are by definition in places lucky enough to have avoided destruction. We derive a new upper bound of one per 10^9 years (99.9% c.l.) on the exogenous terminal catastrophe rate that is free of such selection bias, using the relatively late formation time of Earth. \\ ( http://arXiv.org/abs/astro-ph/0512204 , 21kb) From owner-public@setileague.org Fri Dec 9 12:31:25 2005 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: * X-Spam-Status: No, score=1.3 required=5.5 tests=MSGID_FROM_MTA_HEADER, RCVD_IN_BL_SPAMCOP_NET autolearn=no version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id jB9KVOvh002212 for ; Fri, 9 Dec 2005 12:31:24 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id PAA09955 for public-list; Fri, 9 Dec 2005 15:24:06 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f28.bay114.hotmail.com [65.54.169.38]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id PAA09935; Fri, 9 Dec 2005 15:24:03 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Fri, 9 Dec 2005 12:23:28 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Fri, 09 Dec 2005 20:23:27 GMT X-Originating-IP: [24.39.94.195] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: Urge to Merge: Here Comes Andromeda Date: Fri, 09 Dec 2005 15:23:27 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 09 Dec 2005 20:23:28.0569 (UTC) FILETIME=[6A53B290:01C5FCFE] Sender: owner-public@setileague.org Precedence: bulk Science/Astronomy: * Urge to Merge: Here Comes Andromeda http://www.space.com/searchforlife/seti_doyle_merge_051208.html The Andromeda spiral galaxy will merge with the Milky Way in about six billion years.

They've established an international committee to set the etiquette for inter-galactic contact. And Sydney-based cosmologist Paul Davies just took on the top job. "We need to get the protocol correct and clarified," noted Professor Davies, with Macquarie University's Australian Centre for Astrobiology. "If ET called tonight we'd be in a bit of a muddle about it all," he added, speaking prior to his first meeting as head of the Post-Detection Science and Technology Taskgroup. The body is part of the International Academy of Astronautics and was founded by radio-astronomer Jill Tarter of the Search for Extraterrestrial Intelligence (SETI) Institute in California. "We want the correct details about the discovery event and any interpretation made about it to get out there," commented Dr Tarter, in Australia for a lecture tour supported by Sydney University's Centre for Human Aspects of Science and Technology. According to Dr Tarter - whose SETI exploits were portrayed by Jodie Foster in the 1997 film Contact - if a signal from ET is detected it must be verified quickly and the news spread widely to ensure it's not "co-opted" by interest groups or politicians. "Another caveat is that (scientists) will not transmit a reply until there's a global consensus about whether to reply and what should be said," Dr Tarter claimed.

The formation of the Oort cloud is then reviewed, as well as the primordial sculpting of the Kuiper belt.

To appear in The Astronomical Journal \\ We report spectroscopic observations of HD 27638B, the secondary in a visual binary in which the physically associated primary (separation approximately 19 arcsec) is a B9V star. The secondary shows strong Li 6708 absorption suggesting youth, and has attracted attention in the past as a candidate post-T Tauri star although this has subsequently been ruled out. It was previously known to be a double-lined spectroscopic binary (F8+G6) with a period of 17.6 days, and to show velocity residuals indicating a more distant massive third companion with a period of at least 8 years. Based on our radial velocity measurements covering more than two cycles of the outer orbit, along with other measurements, we derive an accurate triple orbital solution giving an outer period of 9.447 +/- 0.017 yr. The third object is more massive than either of the other two components of HD 27638B, but is not apparent in the spectra. We derive absolute visual magnitudes and effective temperatures for the three visible stars in HD 27638. Isochrone fitting based on those properties gives an age of 200 +/- 50 Myr for the system. We infer also an inclination angle of about 53.3 degrees for the inner orbit of HD 27638B. We detect a near-infrared excess in HD 27638B which we attribute to the third star being a close binary composed of late-type stars. This explains its large mass and lack of a visible signature. Modeling of this excess allows us to infer not only the masses of the components of the unseen companion, but also the inclination angle of the outer orbit (approximately 73 deg). The HD 27638 system is thus at least quintuple. \\ ( http://arXiv.org/abs/astro-ph/0512254 , 370kb) Astrophysics, abstract astro-ph/0509508 From: Soko Matsumura [view email] Date (v1): Fri, 16 Sep 2005 18:07:44 GMT (396kb) Date (revised v2): Thu, 8 Dec 2005 23:52:40 GMT (396kb) Dead Zones and Extrasolar Planetary Properties Authors: Soko Matsumura, Ralph E. Pudritz Comments: 13 pages, 11 figures, minor changes, accepted for publication in MNRAS Most low-mass protostellar disks evolve in clustered environments where they are affected by external radiation fields, while others evolve in more isolated star-forming regions. Assuming that the magneto-rotational instability (MRI) is the main source of viscosity, we calculate the size of a poorly ionized, MRI inactive, and hence low viscosity region - the "dead zone" - in these protostellar disks. We include disk ionization by X-rays, cosmic rays, radioactive elements and thermal collisions, recombination by molecules, metals, and grains, as well as the effect of turbulence stimulation in the dead zone by the active layers lying above it. We also calculate the gap-opening masses of planets, which are determined by a disk's viscosity and a disk aspect ratio, for disks in these environments and compare them with each other. We find that the dead zone is a robust feature of the protostellar disks that is largely independent of their environment, typically stretching out to ~ 15 AU. We analyze the possible effects of dead zones on planet formation, migration, and eccentricity evolution. We show that the gap-opening mass inside the dead zone is expected to be of the order of terrestrial and ice giant mass planets while that outside the dead zone is Jovian or super-Jovian mass planets, largely independent of the star-forming environment. We show that dead zones can significantly slow down both type I and type II planetary migration due to their lower viscosity. We also find that the growth of eccentricity of massive extrasolar planets is particularly favorable through the planet-disk interaction inside the dead zones due to the large gaps expected to be opened by planets. http://arxiv.org/abs/astro-ph/0509508 Paper: astro-ph/0512207 Date: Wed, 7 Dec 2005 22:00:09 GMT (827kb) Title: Survey for Transiting Extrasolar Planets in Stellar Systems: III.

We characterize the survey detection probability via Monte Carlo injection and recovery of realistic limb-darkened transits. We use this to derive upper limits on the fraction of cluster members with close-in Jupiter-radii, RJ, companions. We carefully analyze the random and systematic errors of the calculation. For similar photometric noise and weather properties as this survey, observing NGC 1245 twice as long results in a tighter constraint on "Hot Jupiter", HJ, companions than observing an additional cluster of similar richness as NGC 1245 for the same length of time as this survey. This survey observed ~870 cluster members. If 1% of stars have 1.5 RJ HJ companions, we expect to detect one planet for every 5000 dwarf stars observed for a month. To reach a ~2% upper limit on the fraction of stars with 1.5 RJ HJ companions, we conclude a total sample size of ~7400 dwarf stars observed for at least a month will be needed. Results for 1.0 RJ companions, without substantial improvement in the photometric precision, will require a small factor larger sample size. \\ ( http://arXiv.org/abs/astro-ph/0512207 , 827kb) From owner-public@setileague.org Mon Dec 12 11:53:32 2005 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: * X-Spam-Status: No, score=1.3 required=5.5 tests=MSGID_FROM_MTA_HEADER, RCVD_IN_BL_SPAMCOP_NET autolearn=no version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id jBCJrWqF004487 for ; Mon, 12 Dec 2005 11:53:32 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id OAA20451 for public-list; Mon, 12 Dec 2005 14:47:32 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f23.bay114.hotmail.com [65.54.169.33]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id OAA20445; Mon, 12 Dec 2005 14:47:30 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Mon, 12 Dec 2005 11:46:59 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Mon, 12 Dec 2005 19:46:58 GMT X-Originating-IP: [24.39.94.195] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: Alien Monday on the National Geographic Channel Date: Mon, 12 Dec 2005 14:46:58 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 12 Dec 2005 19:46:59.0460 (UTC) FILETIME=[D0C16C40:01C5FF54] Sender: owner-public@setileague.org Precedence: bulk MONDAY, DECEMBER 12 Is it Real?: "UFOs" at 8P et/pt Numerous people believe they have spotted glowing alien spacecraft hovering over Earth - and some even claim to have been abducted by them.
