Abbott, et al, M. Kramer, A. G. Lyne Comments: 21 pages LIGO prodolzhaet sbor dannyh. Komanda regulyarno vydaet verhnie predely na gravitacionno-volnovoe izluchenie ot radiopul'sarov (obo vsem etom, kstati, mozhno pochitat' vo vtorom nomere "Vokrug Sveta").

Authors: Kate Y. L. Su et al. Comments: 5 pages, emulateapj format, accepted for publication in ApJ Letters S pomosh'yu kosmicheskoi infrakrasnoi observatorii Spitcer udalos' uvidet' disk vokrug central'noi zvezdy izvestnoi planetarnoi tumannosti "Ulitka" (NGC 7293). Central'noi zvezdoi yavlyaetsya goryachii (110 000K) belyi karlik. Sushestvuyut zhestkie ogranicheniya na vozmozhnuyu dvoistvennost' zvezdy. Na risunke pokazano izobrazhenie tumannosti "Ulitka" na dline volny 70 mikron. Avtory polagayut, chto nalichie diska mozhet byt' svyazano so stolknoveniyami ob'ektov, vhodyashih v strukturu tipa nashego poyasa Koipera, ili s ispareniem komet, vhodyashih v analog oblaka Oorta. Eto bylo by dovol'no lyubopytno, t.k. zvezda, ochevidno, proshla stadiyu giganta i sbrosila obolochku. Znachit, ili komety, ili planetoidy smogli etot epizod v zhizni zvezdy perezhit'. populyarnaya stat'ya astro-ph/0702298 Nedostayushie stranicy v fotoal'bome o mladenchestve nashei vselennoi (Missing Pages in Our Photo Album of the Infant Universe) Authors: Abraham Loeb Comments: 7 pages, Popular level review, to appear in "Physica Plus" magazine, Vol. 8; a modified version with original artwork appeared in Scientific American, 295, 46, 2006 Stat'ya posvyashena "temnomu periodu" v zhizni vselennoi. Eta epoha sootvetstvuet promezhutku mezhdu epohoi rekombinacii (o kotoroi my znaem blagodarya izucheniyu reliktovogo izlucheniya) i vremenem poyavleniya pervyh galaktik. obzor hep-th/0702059 Ob inflyacii v teorii strun (On Inflation in String Theory) Authors: Renata Kallosh Comments: 38 pages, 8 figures. Based on an invited talk at "Inflation + 25", 22nd IAP Colloquim, Paris (June 2006). To be published in the Proceedings (Springer Lecture Notes, 2007) Podrobnyi (i dovol'no ponyatnyi) obzor, posvyashennyi zayavlennoi tematike. astro-ph/0702331 Statisticheskoe issledovanie nalakticheskih ostatkov sverhnovyh, ispol'zuya obzor PMN (A Statistical Study of Galactic SNRs using the PMN Survey) Authors: M. Stupar et al. Comments: 14 pages, 7 figures. Accepted for publishing in Astrophysics and Space Science PMN - Parkes-MIT-NRAO. Eto radioobzor neba, kotoryi pozvolyaet izuchat' prakticheski vse ostatki sverhnovyh v nashei Galaktike. Tochnee, 164 iz 231 ostatka. Avtory vybrali 138 ostatkov, dlya kotoryh dannye imeyut dostatochno vysokoe kachestvo, i predstavili rezul'taty analiza etih ob'ektov. Vazhnym rezul'tatom raboty yavlyaetsya utochnenie parametrov metoda, kotoryi pozvolyaet opredelyat' rasstoyaniya do ostatkov. astro-ph/0702333 Kosmicheskii dekonstrukcionizm (Cosmic Deconstructionism) Authors: Lawrence M. Krauss, Glenn D. Starkman Comments: 4 pages Esli temnaya materiya sostoit iz slabovzaimodeistvuyushih chastic (WIMP), to eti chasticy annigiliruyut drug s drugom (estestvenno, chasticy i antichasticy). T.o., v otdalennom budushem temnoi materii budet stanovit'sya men'she. Eto mozhet vliyat' na svoistva ryada ob'ektov, naprimer, na karlikovye sputniki galaktik. Harakter etogo vliyaniya i obsuzhdaetsya avtorami. Razumeetsya, vremya, kogda takoi process stanet dinamicheski vazhnym, chudovishno veliko (zavedomo posle 2008 goda). Krome togo, esli est' temnaya energiya tipa lyambda-chlena, to i bez annigilyacii temnoi materii vse razletitsya. Tem ne menee, ne lishne znat', chto v tom sluchae, esli v budushem materiya opyat' stanet dominirovat' (naprimer, vklad temnoi energii budet umen'shat'sya), to vse ravno budushee (dazhe bez temnoi materii i temnoi energii) ne takoe uzh i svetloe. Skopleniya galaktik raspadutsya, sputniki galaktik razletyatsya, a vse iz-za annigilyacii chastic temnoi materii. astro-ph/0702336 Poisk s pomosh'yu H.E.S.S. pul'siruyushego gamma-izlucheniya ochen' vysokoi energii ot molodyh radiopul'sarov (Search for Pulsed VHE Gamma-Ray Emission from Young Pulsars with H.E.S.S) Authors: The HESS Collaboration: F.Aharonian, et al Comments: 13 pages, 11 figures, accepted for publication in A&A H.E.S.S. otnablyudal desyatok pul'sarov, ot kotoryh mozhno bylo by ozhidat' zametnogo potoka gamma-izlucheniya vysokoi energii. Rezul'tat nulevoi. Uchityvaya velikolepnye parametry H.E.S.S., eto ochen' ser'eznye verhnie predely. Oni ukazyvayut na to, chto na energiyah poryadka TeV v spektre pul'sarov dolzhen byt' zagib. Eto daet ser'eznye ogranicheniya na modeli izlucheniya pul'sarov. astro-ph/0702342 Planety v dvoinyh sistemah: daet li segodnyashnyaya konfiguraciya dannye o processe formirovaniya? (Planets in binary systems: is the present configuration indicative of the formation process?) Authors: F. Marzari, M. Barbieri Comments: 5 pages, 5 figures Accepted for publication on A&A Otvet na vopros, zadannyi v zagolovke, otricatel'nyi. Avtory chislenno rasmatrivayut evolyuciyu planetnyh orbit v ierarhicheskoi troinoi sisteme (dve zvezdy formiruyut tesnuyu paru, a tret'ya krutitsya na shirokoi orbite vokrug pary). Planety obrazuyutsya vokrug bolee massivnoi zvezdy v pare. V hode evolyucii odna iz zvezd troinoi sistemy vyletaet. Razumeetsya, orbity planet v ostavsheisya dvoinoi zametno otlichayutsya ot togo, chto bylo v samom nachale. astro-ph/0702347 Neobychnyi dvoinoi pul'sar PSR J1744-3922: peremennost' radio potoka, nablyudeniya v blizhnem IK i evolyuciya (The Unusual Binary Pulsar PSR J1744-3922: Radio Flux Variability, Near-infrared Observation and Evolution) Authors: R. P. Breton et al. Comments: 18 pages, 8 figures, accepted for publication of ApJ Avtory polagayut, chto etot neobychnyi pul'sar i eshe neskol'ko drugih obrazuyut osobyi klass ob'ektov, vydelyayushiisya sredi osnovnoi massy dvoinyh pul'sarov. V chastnosti, dlya ih formirovaniya nuzhen osobyi evolyucionnyi kanal. Magnitnoe pole pul'sara okazyvaetsya slishkom sil'nym, a period slishkom dlinnym, uchityvaya parametry dvoinoi sistemy. Krome togo, pul'sar pokazyvaet sil'nuyu peremennost', chto netipichno dlya dvoinyh pul'sarov s malomassivnymi kompan'onami na orbitah s korotkim orbital'nym periodom. miniobzor astro-ph/0702350 Antiveshestvo v Mlechnom Puti (Antimatter in the Milky Way) Authors: C. Bambi, A.D. Dolgov Comments: 12 pages, no figures Avtory rassmatrivayut vozmozhnye nablyudatel'nye proyavleniya ob'ektov iz antiveshestva v nashei Galaktike. Yasno, chto kogda my govorim ob otsutstvii antiveshestva, my imeem vvidu, chto ego "men'she, chem nekotoroe kolichestvo, kotoroe uzhe zametili by". Zametili by, veroyatnee vsego, po gamma-izlucheniyu, voznikayushemu v rezul'tate annigilyacii. Tak chto, kak eto chasto byvaet, my "nikogda ne govorim nikogda", a prosto stavim verhnie predely. S nablyudatel'noi tochki zreniya situaciya seichas horoshaya: est' ser'eznye gamma-teleskopy, v samom skorom vremeni poletyat gamma-observatorii GLAST i AGILE, seichas na orbite rabotaet eksperiment PAMELA, prednaznachennyi dlya poiska antiyader, skoro dolzhen byt' zapushen AMS. AMS - eto eshe bolee krupnyi, chem PAMELA magnitnyi spektrometr, kotoryi dolzhny ustanovit' na MKS. No, poskol'ku ves' grafik MKS sbilsya, vvod v stroi AMS vse vremya otkladyvaetsya. T.o., v blizhaishem budushem mozhno ozhidat' kakih-to otkrytii, ili, skoree vsego, eshe bolee zhestkih predelov. Rezyume avtorov, estestvenno, ne soderzhit nikakih zhestkih utverzhdenii. V Galaktike est' mesto dlya nekotorogo kolichestva ob'ektov iz antiveshestva. Odnako poka nikakih sil'nyh argumentov v pol'zu ih sushestvovaniya net, a nablyudeniya dayut vse bolee strogie verhnie predely. Obsudit' v ZhZh-soobshestve ru_astroph.
