Sazhin et al. Comments: 5 pages, 3 figures Vozmozhnaya sensaciya rassosalas'. Vse pomnyat, chto neskol'ko let nazad novostnye lenty pestreli soobsheniyami o tom, chto rossiiskie i ital'yanskie uchenye otkryli ob'ekt, kotoryi mog by byt' sluchaem linzirovaniya na kosmicheskoi strune. Razumeetsya, srazu vyskazyvalsya i razumnyi skepticizm. I vot posle dopolnitel'nyh nablyudenii stalo okonchatel'no yasno, chto nikakaya eto ne kosmicheskaya struna. Zhal' .... obzor gr-qc/0601085 Petlevaya kvantovaya kosmologiya (Loop Quantum Cosmology) Authors: Martin Bojowald Comments: 104 pages, 10 figures; Living Rev. Relativity 8 (2005) 11 Obzor po kosmologii, osnovyvayusheisya na modeli petlevoi kvantovoi gravitacii. Stat'ya ochen' slozhnaya, na moi vzglyad. Sobstvenno, tema obyazyvaet, i rabota napisana ne dlya shirokoi publiki. Tem ne menee, kogo-to mozhet zainteresovat' takoi podhod v kvantovoi kosmologii. obzor astro-ph/0601502 Evolyuciya massivnyh zvezd maloi metallichnosti (Stellar evolution of massive stars at very low metallicities) Authors: R. Hirschi, et al. Comments: 29 pages, 10 figures, Reviews of Modern Astronomy 19, proceedings for 79th Annual Scientific Meeting of the Deutsche Astronomische Gesellschaft 2005 Podrobnyi obzor, imeyushii otnoshenie k samym pervym zvezdam vo Vselennoi: k tomu kak oni zhili i vzryvalis'. astro-ph/0601521 Parallaks i sobstvennoe dvizhenie PSR J0030+0451 (The Parallax and Proper Motion of PSR J0030+0451) Authors: Andrea N. Lommen et al. Comments: accepted by ApJ, 6 pages, 3 figures, 2 tables Poluchen parallaks odinochnogo millisekundnogo pul'sara v diske Galaktiki. Rasstoyanie okazalos' v sootvetstvii s opredelennym po mere vrasheniya. Ono sostavlyaet okolo 300 pk. Eto odin iz samyh medlennyh pul'sarov: ego skorost' menee 20 km/s. astro-ph/0601528 Izuchenie galaktik gamma-vspleskov (GRB Host Studies (GHostS)) Authors: S. Savaglio et al. Comments: 6 pages, 4 figures. To appear in the proceedings of the 16th Annual October Astrophysics Conference in Maryland "Gamma Ray Bursts in the Swift Era", eds. S. Holt, N. Gehrels & J. Nousek Opisan proekt po sostavleniyu kataloga i izucheniyu t.n. hozyaiskih galaktik (host galaxies) kosmicheskih gamma-vspleskov. Na segodnyashnii den' katalog naschityvaet 32 galaktiki, v kotoryh nablyudalis' gamma-vspleski. Napomnyu, chto odnim iz vazhneishih sobytii proshlogo goda stalo obnaruzhenie poslesvecheniya (oreolov) ot korotkih gamma-vspleskov, chto pozvolilo ponyat', v kakih galaktikah oni proishodyat. astro-ph/0601534 Vodyanoi led na sputnike ob'ekta poyasa Koipera 2003 EL61 (Water Ice on the Satellite of Kuiper Belt Object 2003 EL61) Authors: K.M Barkume, M.E. Brown, E.L. Schaller Comments: 8 pages Poluchen IK-spektr yarchaishego sputnika ob'ekta Poyasa Koipera. V spektre obnaruzheny detali, kotorye pozvolyayut govorit' o sushestvovanii na sputnike vodyanogo l'da. Eto ne pervoe obnaruzhenie vodyanogo l'da v poyase Koipera. Odnako, veroyatno, chto eto nebezinteresno dlya nashih chitatelei. Vdogonku. V stat'e astro-ph/0601618 Trujillo i dr. soobshayut ob otkrytii vodyanogo l'dya na samom 2003EL61. obzor astro-ph/0601538 Kosmologicheskie ogranicheniya po galakticheskomu skuchivaniyu (Cosmological constraints from galaxy clustering) Authors: Will J. Percival Comments: 30 pages, 13 figures. Lecture given at Third Aegean Summer School, The invisible universe: Dark matter and Dark energy Obrashaem vashe vnimanie na etot obzor, t.k. v spisok samyh interesnyh sobytii proshlogo goda voshel rezul'tat, svyazannyi s obnaruzhenie akusticheskogo pika po dannym o krupnomasshtabnom raspredelenii galaktik. Dannyi obzor posvyashen razboru takih nablyudenii, ob'yasneniyu ih vazhnosti t.p. vesham. astro-ph/0601563 Otkrytie s pomosh'yu gravitacionnogo linzirovaniya holodnoi planety s massoi 5.5 mass Zemli (Discovery of a Cool Planet of 5.5 Earth Masses Through Gravitational Microlensing) Authors: J.-P. Beaulieu et al. Comments: 10 pages Obnaruzheny planeta okolo M-karlika (massa 0.1-0.4 massy Solnca). Massa prlanety sostavlyaet 3-11 mass Zemli. Rasstoyanie ot zvezdy - 2-3.5 a.e. Esli brat' ne polnye intervaly neopredelennostei, a naibolee veroyatnye znacheniya, to massa zvezdy - 0.22 massy Solnca, massa planety - 5.5 mass Zemli, a rasstoyanie - 2.6 astronomicheskih edinic. Nablyudalos' linzirovanie dalekoi zvezdy na opisannoi vyshe sisteme. Harakter krivoi bleska pri linzirovanii opredelyaetsya svoistvami linzy. V chastnosti, mozhno iskat' planety s massami ot massy Zemli do massy Yupitera na udalenii 1-5 a.e. ot central'noi zvezdy (razumeetsya, rech' idet o tipichnyh znacheniyah). Rasstoyanie ot nas do linzy primerno 5.5-7.5 kpk. Avtory otmechayut, chto teoriya obrazovaniya planet kak raz predskazyvaet, chto vokrug legkih zvezd kak raz dolzhny nablyudat'sya planety, s parametrami, sootvetstvuyushimi opisannym. Na risunke pokazano sobytie mikrolinzirovaniya. Special'no vydelen pichok, svyazannyi s planetoi. Stat'ya, razumeetsya, opublikovana v Nature. miniobzor astro-ph/0601576 Polyarizaciya reliktovogo izlucheniya (Cosmic Microwave Background Polarization) Authors: James G. Bartlett Comments: Review given at TAUP 2005, 8 pages V poslednie gody mnogo govoryat o polyarizacii reliktovgo izlucheniya. Izuchenie sootvetstvuyushih parametrov kosmicheskogo mikrovolnovogo fona pozvolit uznat' mnogo novogo o nashei Vselennoi. Cherez paru let budet zapushen sputnik Plank, special'no dlya etogo prdenaznachennyi. Poka zhe polyarizaciyu pytayutsya izmeryat' v nazemnyh i balonnyh eksperimentah. astro-ph/0601580 Udachnyi celevoi poisk giperbystryh zvezd (A Successful Targeted Search for Hypervelocity Stars) Authors: Warren R. Brown, Margaret J. Geller, Scott J.Kenyon, Michael J. Kurtz Comments: 5 pages, submitted to ApJ Letters V nachale napomnyu, chto v poslednie gody udalos' otkryt' neskol'ko zvezd, kotorye, blagodarya svoim skorostyam, sumeli zabrat'sya na bol'shie (desyatki kpk) rasstoyaniya ot centra Galaktiki. Prichem daleko oni uleteli i ot galakticheskogo diska. Kak oni priobretayut takie skorosti? Naibolee veroyatno, chto eto byla forma "gravitacionnogo manevra" v pole nashei sverhmassivnoi chernoi dyry. Avtory stat'i proveli special'nyi poisk takih zvezd, i obnaruzhili eshe paru. Obe zvezdy imeyut skorosti okolo 600 km/s. Rasstoyanie odnoi ot centra sostavlyaet okolo 55 kpk, a vtoroi - azh 75 kpk. Vse eto massivnye zvezdy (spektral'nyi klass V). Oni byli vybrosheny iz centra Galaktiki okolo 100 millionov let nazad. astro-ph/0601612 Zadacha dvuh tel s kosmologicheskoi postoyannoi i nablyudatel'nye ogranicheniya ( Two-body problem with the cosmological constant and observational constraints) Authors: Ph. Jetzer, M. Sereno Comments: 8 pages, accepted for publication in Phys. Rev. D Vspominaetsya Dovlatov: "Kniga interesnaya, no slozhnaya" (eto bylo pro "Iosif i ego brat'ya" Tomasa Manna, kstati, ya sam nikak ne soberus' prochitat'). V stat'e razobrana zadacha dvuh tel s uchetom vklada kosmologicheskoi postoyannoi. Voobshe, problema povedeniya, skazhem, planet v Solnechnoi sisteme ili zemnyh sputnikov s uchetom kosmologicheskih effektov (a kosmologicheskuyu postoyannuyu mozhno smelo k nim otnesti) vyzyvaet interes. I voprosy. Vot vo vtorom nomere GEO ya uspokaival chitatelya v tom smysle, chto rasshirenie Vselennoi ne menyaet orbitu Luny i iskusstvennyh sputnikov. Po-krainei mere, effekt ne nablyudaetsya, i voobshe, v blizhaishie paru milliardov let nam nichego ne grozit. Dazhe s uchetom vozmozhnosti "Bol'shogo razryva" v nastoyashee vremya nikakih nablyudaemyh effektov v Solnechnoi sisteme net. Tem ne menee, podrobnogo razbora zadachi dvuh tel pri nalichii kosmologicheskoi postoyannoi ya ne vstrechal (vozmozhno, ploho smotrel; na odin iz svezhih e-printov ssylayutsya sami avtory - gr-qc/0511137). I vot ... Kak ya preduprezhdal, stat'ya slozhnaya. Vozmozhno, chto bol'shinstvo prochtet lish' razdely 1 i 5-6. Razdely 1 i 6 eto vvedenie i zaklyuchenie, sootvetstvenno. A v razdele 5 predstavleny nablyudatel'nye ogranicheniya na velichinu kosmologicheskoi postoyannoi, kotorye mozhno poluchit', nablyudaya sistemy razlichnogo tipa. Kak ni stranno, no nailuchshee dayut vovse ne dvoinye radiopul'sary, a dannye po Solnechnoi sisteme. Konechno, smysl v takih ogranicheniyah dostatochno akademicheskii. Ved' po sobstvenno kosmologicheskim dannym my primerno znaem velichinu kosmologicheskoi postoyannoi, a luchshie ogranicheniya po dannym o dvizhenii Zemli i Marsa lezhat na 10 poryadkov vyshe. Tem ne menee. takie predely nado poluchat'. Ved' proveryayut zhe, naprimer, deistvie zakona vsemirnogo tyagoteniya na raznyh masshtabah. I, kto znaet, priroda mozhet byt' ustroena slozhnee, chem my sebe predstavlyaem. Osnovnoi effekt kosmologicheskoi postoyannoi na orbitu, kak pishut avtory, zaklyuchaetsya v precessii pericentra. Mozhno rasschitat' skorost' precessii. V pervom priblizhenii ona okazyvaetsya proporcional'noi kosmologicheskoi postoyannoi. Effekt znachitelen dlya malomassivnyh sistem na shirokih orbitah (imenno poetomu, dlya dvoinyh pul'sarov on ne tak vyrazhen, kak dlya planet v Solnechnoi sisteme). Smotrite podrobnyi kommentarii Igorya Ivanova. miniobzor astro-ph/0601625 Magnitnye svoistva zvezd promezhutochnyh mass (Magnetic properties of intermediate-mass stars) Authors: G.A. Wade Comments: 11 pages Interesnyi obzor, posvyashennyi magnitnym polyam zvezd s massami okolo 2-4 solnechnyh (v osnovnom eto zvezdy spektral'nogo klassa A). Obzor horosho tem, chto na 11 stranicah umestilos' po chut'-chut' pro vse. Otmechu, horoshuyu vvodno-istoricheskuyu chast' i ponyatnoe opisanie togo, kak polya izmeryayut. astro-ph/0601627 Katalog rentgenovskih istochnikov v central'nyh 150 pk Galaktiki po dannym Chandra (A Chandra Catalog of X-ray Sources in the Central 150 pc of the Galaxy) Authors: Muno et al. Comments: 16 pages, incl. 9 figures, 3 in color. Submitted to ApJ. Predstavleny rezul'taty nablyudenii sputnikom Chandra central'noi chasti nashei Galaktiki. Itogovyi katalog vklyuchaet v sebya pochti 2000 istochnikov. Razumeetsya, ne vse oni lezhat v diske s radiusom v 150 pk: chast' istochnikov popala v katalog iz-za effekta proekcii. 1352 istochnika imeyut bol'shoe pogloshenie (t.e. ih svet sushestvenno oslablen mezhzvezdnoi sredoi), i podavlyayushee bol'shinstvo iz nih dolzhny v samom dele lezhat' v oblasti centra Galaktiki. Eshe 549 istochnikov imeyut men'shee pogloshenie, sootvetstvenno, oni lezhat mezhdu nami i centrom Galaktiki. Mozaika oblasti nablyudenii. Uglovoi razmer 2 na 0.8 gradusa; odin gradus na rasstoyanii galakticheskogo centra sootvetstvuet primerno 150 pk. Avtory polagayut, chto pochti 90 procentov vseh zaregistrirovannyh istochnikov yavlyayutsya kataklizmicheskimi peremennymi (eto dvoinye sistemy, v kotoryh akkreciya idet na belyi karlik). Ostal'nye 10 procentov eto akkreciruyushie neitronnye zvezdy i chernye dyry, molodye neitronnye zvezdy, a takzhe massivnye zvezdy v dvoinyh sistemah, gde est' stolknoveniya zvezdnyh vetrov. Avtory nadeyutsya, chto k koncu goda katalog mozhet byt' sushestvenno dopolnen i uluchshen, t.k. zaplanirovany novye glubokie nablyudeniya oblasti centra Galaktiki na Chandre. obzor astro-ph/0601654 Kratkaya istoriya zaneptunovogo kosmosa (A Brief History of Trans-Neptunian Space) Authors: E. Chiang et al. Comments: Refereed, accepted, formatted review chapter for Protostars and Planets V compendium Dovol'no bol'shoi (17 dvuhkolonochnyh stranic) obzor po poyasu Koipera i t.p. Nazvanie ne dolzhno sbivat' s tolku. Prosto Hoking slishkom uzh raskrutil oborot "kratkaya istoriya" (primerno, kak v stalinskom SSSR "kratkii kurs"). Kak raz "kratkii kurs" podoshlo by bol'she, t.k. v obzore istorii malo, a vot dannyh i t.p. poleznyh veshei mnogo. Rekomenduetsya k prochteniyu vsemi, kto interesuetsya poyasom Koipera i t.p. obzor nucl-th/0601086 Fizika plotnogo adronnogo veshestva i kompaktnye zvezdy (The physics of dense hadronic matter and compact stars) Authors: Armen Sedrakian Comments: 84 pages, 30 figures, to apper in Prog.
