Obzory preprintov astro-ph Vypusk N63 astro-ph za 16 - 31 dekabrya 2003 goda: izbrannye stat'i Referaty otdel'nyh statei astro-ph/0312356 Otkrytie pekulyarnogo pul'sara v Malom Magellanovom Oblake (A Discovery of a Peculiar Pulsar in the Small Magellanic Cloud) Authors: Masaru Ueno et al. Comments: 5 pages, 5 figures, accepted in PASJ V stat'e opisyvayutsya ochen' neobychnye svoistva rentgenovskogo pul'sara s Be-zvezdoi IKT1 (=RXJ0047.3-7312) po dannym nablyudenii, provedennyh orbital'noi observatoriei XMM-N'yuton v oktyabre 2000 g. U pul'sara nablyudayutsya sushestvennye izmeneniya potoka s periodom okolo 4000 s i kogerentnye pul'sacii s periodom 263+/-1 s. V hode nablyudenii potok sushestvenno menyalsya, ego srednee znachenie v intervale energii 0.7-10 keV sostavlyalo 2.9x10-12 erg/sm2/s, chto primerno v 10 raz bol'she, chem pri nablyudeniyah s ROSAT a v 1999 g. Vse pekulyarnye svoistva nablyudalis' tol'ko v myagkoi spektral'noi komponente izlucheniya (T=0.6 keV) i ne zatragivali zhestkuyu (s T=5.8 keV). miniobzor astro-ph/0312378 Vspyshki i koronal'nye struktury u zvezd (Stellar Flares and Coronal Structure) Authors: M. Guedel (PSI, Switzerland) Comments: 10 pages, 13 figures, proceedings of IAU Symposium 219 My horosho znaem Solnechnye vspyshki i processy v korone Solnca. Ochevidno, chto podobnye processy idut i v drugih zvezdah, podobnyh Solncu, prosto ih gorazdo trudnee nablyudat'. Trudnee, no uzhe mozhno. V dannoi rabote privedeny dannye o koronal'nyh i vspyshechnyh strukturah u drugih zvezd, poluchennye vo vremya ih zatmenii i po interferometricheskim nablyudeniyam. Obzor horosho proillyustrirovan. obzor astro-ph/0312369 Odinochnye neitronnye zvezdy: astrofizicheskii obzor (Isolated neutron stars: An astrophysical perspective) Authors: Sergei Popov, Roberto Turolla Comments: 20 pages, 6 figures, Review talk given at the NATO Advanced Research Workshop On Superdense QCD Matter and Compact Stars, 27 Sep - 4 Oct 2003, Yerevan, Armenia Eto obzornyi doklad, prochitannyi na, v obshem-to, fizicheskoi konferencii po kvarkovym zvezdam i ekstremal'nym sostoyaniyam veshestva. V pervoi chasti daetsya spisok naibolee interesnyh rezul'tatov, poluchennyh za poslednie 2-3 goda. Zatem dayutsya bolee podrobnye kommentarii po spektram i atmosferam neitronnyh zvezd, po akkrecii na odinochnye neitronnye zvezdy, i po nekotorym drugim voprosam, predstavlyayushim interes dlya avtorov obzora. astro-ph/0312382 "Oziris" (HD209458b), isparyayushayasya planeta ("Osiris" (HD209458b), an evaporating planet) Authors: Alfred Vidal-Madjar & Alain Lecavelier des Etangs (IAP) Comments: 8 pages, 7 figures Nablyudeniya prohoda planety po disku zvezdy HD209458 solnechnogo tipa pokazali udivitel'nuyu kartinu. Razmer planety raven 4.3RJ, chto prevyshaet razmer radiusa Rosha dlya etoi planety, sostavlyayushii 3.6RJ. Eto oznachaet, chto planeta teryaet svoi vneshnie sloi. Etot fakt podtverzhdayut i izmereniya luchevyh skorostei, registriruyushie potok veshestva s otnositel'noi skorost'yu -130 km/s (znak minus oznachaet dvizhenie k nam), t.e. vyshe skorosti ubeganiya ot planety. Etomu zhe ob'ektu posvyashena stat'ya astro-ph/0312384 togo zhe nauchnogo kollektiva "Temp ispareniya goryachih Yupiterov i obrazovanie Htonianskih planet". astro-ph/0312399 Dlinnye i korotkie gamma-vspleski i otdacha pul'sarov (Long and short gamma-ray bursts, and the pulsar kicks) Authors: Alexander Kusenko and Dmitry V. Semikoz Comments: 8 pages, 1 figure Ideya raboty ochen' ponyatna: korotkie gamma vspleski ochen' pohozhi na pervye neskol'ko sekund dlinnyh gamma-vspleskov, kotorye po kakoi-to prichine vnezapno zakonchilis'. Avtory predpolagayut, chto eto imenno tak. Gamma-vspleski porozhdayutsya v hode sverhmoshnoi akkrecii veshestva iz akkrecionnogo diska (obrazovavshegosya iz obolochek kollapsiruyushei zvezdy) na neitronnuyu zvezdu ili chernuyu dyru. Poka idet akkreciya my nablyudaem gamma-izluchenie. No esli za neskol'ko sekund neitronnaya zvezda priobretaet vysokuyu skorost', to ona mozhet vyletet' iz diska i vsplesk prekratitsya. astro-ph/0312413 Zavisyashaya ot fazy liniya poglosheniya v spektre rentgenovskogo pul'sara RX J0720.4-3125 (A phase-dependent absorption line in the spectrum of the X-ray pulsar RX J0720.4-3125) Authors: F. Haberl et al. Comments: 9 pages, 10 figures, Submitted to A&A V spektre odinochnoi neitronnoi zvezd RX J0720.4-3125 observatoriya XMM-N'yuton obnaruzhila spektral'nuyu liniyu s energiei 400 eV Shirina i polozhenie linii menyayutsya sinhronno s fazoi vrasheniya neitronnoi zvezdy. Iz etih dannyh poluchaetsya ocenka magnitnogo polya 5x1013 Gs. Ocenka soglasuetsya s dannymi po tormozheniyu vrasheniya pul'sara. astro-ph/0312429 Nablyudeniya i teoriya linzirovannogo kvazara s bol'shim razdeleniem izobrazhenii SDSS J1004+4112 (Observations and Theoretical Implications of the Large Separation Lensed Quasar SDSS J1004+4112) Authors: M. Oguri et al. Comments: 21 pages, 24 figures, 5 tables, submitted to ApJ Kvazar, fotografiya kotorogo pokazana nizhe, linzirovan, yasno vidny chetyre izobrazheniya. Seichas, posle provedeniya massovyh obzorov kvazarov i galaktik, takih ob'ektov izvestno uzhe dostatochno mnogo. I v dannom izobrazhenii net nichego osobennogo, krome odnogo: rasstoyanie mezhdu naibolee udalennymi izobrazheniyami dannogo kvazara sostavlyaet 14.62". Etot kvazar, raspolozhennyi na z=1.734 linziruetsya ne galaktikoi, a skopleniem galaktik, raspolozhennom na z=0.68. miniobzor astro-ph/0312470 Budushee rentgenovskoi spektroskopii galakticheskih dvoinyh chernyh dyr (The Future of X-ray Spectroscopy of Galactic Black Hole Binaries) Authors: Michael A. Nowak Comments: 8 pages, 7 figures V etom malen'kom obzore perepleteny dve temy: 1) chto mogut uvidet' uzhe deistvuyushie i gotovyashiesya k zapusku rentgenovskie observatorii, 2) kakie effekty mozhno obnaruzhit' v rentgenovskih zvezdnyh istochnikah s chernymi dyrami. astro-ph/0312518 Ellipticheskie galaktiki s aktivnym zvezdoobrazovaniem na nebol'shih krasnyh smesheniyah po dannym Sloanovskogo cifrovogo obzora neba (Actively Star Forming Elliptical Galaxies at Low Redshifts in the Sloan Digital Sky Survey) Authors: Masataka Fukugita et al. Comments: 14 pages, Accepted for publication in Astrophys. J. Letters Obychno schitaetsya, chto v ellipticheskih galaktikah novye zvezdy prakticheski ne obrazuyutsya. Dlya bol'shinstva iz nih tak ono i est', no ne dlya vseh ... V vyborke yarkih blizkih (po kosmologicheskim merkam) galaktik Sloanovskogo obzora sredi ellipticheskih galaktik okazalis' ob'ekty s zametnym tempom rozhdeniya zvezd. Galaktiki byli vydeleny v nachale po svoim morfologicheskim harakteristikam, a zatem po linii vodoroda Hα. Chislo podobnyh ob'ektov neveliko - desyatye doli procenta ot polnoi vyborki - odnako, otkrytie, esli ono zatem budet podtverzhdeno, chrezvychaino interesno, v tom chisle i dlya nashego ponimaniya evolyucii Vselennoi. astro-ph/0312533 Voidy v dvuhgradusnom (2dF) obzore galakticheskih krasnyh smeshenii (Voids in the 2dF Galaxy Redshift Survey) Authors: Fiona Hoyle, Michael S. Vogeley Comments: 36 pages, Submitted to ApJ Voidy - eto gigantskie pustoty, v kotoryh fakticheski net yarkih galaktik. Imeyushiesya nemnogochislennye "zvezdnye ostrova" obychno raspolagayutsya blizhe k granicam voidov, a central'nye oblasti sovsem izbegayutsya galaktikami. Avtory ispol'zuyut dannye po 245,591 galaktikam do krasnogo smesheniya z poryadka 0.2. Naideno 289 voidov s radiusom bolee 10-12 Mpk. Oni sostavlyayut primerno 40 procentov ob'ema Vselennoi. miniobzor! astro-ph/0312542 Skorosti neitronnyh zvezd i asimmetriya vzryva sverhnovoi (Neutron Star Kicks and Supernova Asymmetry) Authors: Dong Lai Comments: 11 pages, to appear in 3D Signatures of Stellar Explosion, a workshop honoring J.C. Wheeler's 60th Birthday Odnim iz vazhneishih svoistv neitronnyh zvezd yavlyayutsya ih nachal'nye skorosti, t.k. po vsei vidimosti oni nesut na sebe otpechatok vzryva sverhnovoi. Pri vzryve vydelyaetsya kolossal'naya energiya - 1053 erg (1046 Dzh). Bol'shaya ee chast' unositsya neitrino. Ostal'noe izluchaetsya v vide elektromagnitnogo i gravitacionnogo izlucheniya, a takzhe perehodit v mehanicheskuyu energiyu sbroshennogo veshestva. Dazhe esli dopustit' nebol'shuyu (poryadka procenta) asimmetriyu vzryva, to obrazovavshiisya kompaktnyi ostatok poluchit' kik (tolchok), v rezul'tate chego my budem potom nablyudat',
