Obzory preprintov astro-ph Vypusk N101 astro-ph za 11 - 20 marta 2005 goda: izbrannye stat'i Referaty otdel'nyh statei astro-ph/0503239 Otkrytie pul'sacii i spektral'noi detali v rentgenovskom izluchenii odinochnoi neitronnoi zvezdy 1RXS J214303.7+065419/RBS 1774 (Detection of pulsations and a spectral feature in the X-ray emission of the isolated neutron star 1RXS J214303.7+065419/RBS 1774) Authors: S. Zane et al. Comments: 21 pages, 5 figures, ApJ accepted Opredelen period dlya eshe odnogo ob'ekta iz Velikolepnoi semerki. Eto istochnik 1RXS J214303.7+065419/RBS 1774. Period okazalsya pohozhim na drugie izvestnye dlya neitronnyh zvezd etogo tipa -- 9.437 sekundy. Krome togo, v spektre obnaruzhena nekotoraya osobennost', no ee priroda poka ostaetsya neizvestnoi. astro-ph/0503243 Otkrytie magnitnyh polei goryachih subkarlikov (Discovery of magnetic fields in hot subdwarfs) Authors: S. J. O'Toole et al. Comments: 9 pages, 7 figures, A&A accepted Goryachie subkarliki lezhat v levoi verhnei chasti diagrammy Gercshprunga-Rassela neskol'ko nizhe i levee glavnoi posledovatel'nosti. S pomosh'yu teleskopa VLT provedeny polyarimetricheskie issledovaniya zvezd klassov sdB i sdO. Rezul'taty govoryat o polyah s napryazhennost'yu 1.5 tysyach Gauss. Otmetim, chto ranee uzhe soobshalos' o nablyudenii magnitnyh polei zvezd etogo tipa, naprimer, polya byli zaregistrirovany na 6-metrovom teleskope v SAO. astro-ph/0503244 Registraciya TeVnyh gamma-luchei ot protyazhennogo istochnika na Milagro (Detection of TeV Gamma-Rays from extended sources with Milagro) Authors: P.M. Saz Parkinson, for the Milagro Collaboration Comments: Poster at "The XXII Texas Symposium on Relativistic Astrophysics", Stanford, USA, December 2004, (TSRA04) Privodyatsya rezul'taty nedavnih nablyudenii na detektore Milagro (Milagro), pozvolivshie zaregistrirovat' zhestkoe izluchenie ot vnutrennei chasti ploskosti Galaktiki, a takzhe ot protyazhennogo istochnika, sovpadayushego s 3EG J0520+2556 (etot ob'ekt, kak yasno iz ego nazvaniya, byl otkryt priborom EGRET na CGRO). astro-ph/0503287 Gravitacionnoe izluchenie akkreciruyushego millisekundnogo pul'sara s magnitnouderzhivaemoi goroi (Gravitational Radiation from an Accreting Millisecond Pulsar with a Magnetically Confined Mountain) Authors: A. Melatos, D. J. B. Payne Comments: 19 pages, 4 figures, accepted for publication in The Astrophysical Journal V kachestve istochnika gravitacionnyh voln rassmotrena neitronnaya zvezda "v interesnom polozhenii". Pri moshnoi akkrecii na neitronnye zvezdy veshestvo sushestvenno izmenyaet strukturu magnitnogo polya. Pole "zaryvaetsya" za schet vypavshego veshestva. Formiruetsya nekotoryi "poyas" na magnitnom ekvatore (veshestvo vypadaet v osnovnom na magnitnye polyusa). V svoyu ochered' magnitnoe pole prepyatstvuet proniknoveniyu chasti veshestva v oblast' magnitnogo ekvatora. T.o. obrazuetsya kucha (gora) veshestva. T.k. magnitnye polyusa vovse ne obyazany sovpadat' s "geograficheskimi" polyusami (t.e. magnitnaya os' ne sovpadaet s os'yu vrasheniya), to zvezda priobretaet kvadrupol'nyi moment, a, sledovatel'no, budet izluchat' gravitacionnye volny. S odnoi storony, avtory pokazyvayut, chto ih bolee sovershenanya ocenka daet amplitudu gravitacionnyh voln vyshe, chem predskazyvalos' ranee. S drugoi storony, velichina vse ravno slishkom mala, chtoby mozhno bylo rasschityvat' na registraciyu sovremennymi versiyami LIGO i VIRGO. obzor astro-ph/0503298 Zony, prigodnye dlya zhizni, vo Vselennoi (Habitable Zones in the Universe) Authors: G. Gonzalez Comments: 71 pages, 3 figures, 1 table; to be published in Origins of Life and Evolution of Biospheres Bol'shoi obzor, posvyashennyi probleme opredeleniya mest, prigodnyh dlya sushestvovaniya zhizni. Krome novyh podhodov (v tom chisle i razrabotannogo samim avtorom obzora) daetsya horoshee istoricheskoe vvedenie, nachinayusheesya azh s serediny 19 veka. astro-ph/0503302 Vozmozhnoe spektroskopicheskoe ukazanie na vnezemnye rasteniya (Vegetation's Red Edge: A Possible Spectroscopic Biosignature of Extraterrestrial Plants) Authors: Sara Seager et al. Comments: 19 pages, 6 figures, to appear in Astrobiology Glyada na etu stat'yu, srazu vspominaesh knizhki Tihova, kotorye chitalis' v detstve (kstati, nel'zya ne otmetit', chto avtory akkuratno ssylayutsya na stat'yu Tihova azh 1947 goda!). Rech' idet o tom, kak po spektral'nym harakteristikam ekzoplanety opredelit' nalichie na nei rastitel'nogo pokrova. Pokazano, chto dannye po peremennosti izlucheniya, a takzhe po rezkim detalyam v spektre mogut vydelit' planety s rastitel'nost'yu. astro-ph/0503304 Nastraivayas' na neitrino ul'travysokih energii - eksperiment ANITA (Tuning into UHE Neutrinos in Antarctica - The ANITA Experiment) Authors: P. Miocinovic et al. Comments: Presented at 22nd Texas Symposium on Relativistic Astrophysics at Stanford, Palo Alto, 13-17 December 2004, (TSRA04-2516) 6 pages, LaTeX, 10 eps figures V 1962 godu Gurgen Askaryan vyskazal gipotezu, chto potok chastic v plotnoi srede budet davat' kogerentnoe cherenkovskoe radioizluchenie. Effekt uzhe nablyudalsya v laboratorii pri obstrele gamma-luchami konteinerov s peskom. Rassmatrivayutsya razlichnye varianty nablyudeniya effekta v "astronomicheskih situaciyah", naprimer, nablyudenie effekta pri prolete chastic skvoz' Lunu. V etom sluchae nash sputnik vystupil by v roli detektoram chastic kosmicheskih luchei. Est' i drugie idei. S odnoi iz nih i svyazan antarkticheskii proekt ANITA. Neitrino vysokoi energii proletaet skvoz' Zemlyu i porozhdaet v antarkticheskom ledyanom pokrove potok chastic. Chasticy dayut radioizluchenie, kotoroe i ulavlivaetsya detektorom. Poka provedeny testy, o kotoryh i rasskazyvaetsya v stat'e. astro-ph/0503306 Lednikovye periody i put' Solnca v Galaktike (Ice Age Epochs and the Sun's Path Through the Galaxy) Authors: D. R. Gies, J. W. Helsel Comments: 14 pages, 3 figures, accepted for publication in ApJ Avtory rasschitali traektoriyu dvizheniya Solnca v Galaktike na protyazhenii poslednih 500 millionov let. Konechno, takie raschety provodilis' i ran'she. Prosto zdes' avtory ispol'zovali bolee tochnye dannye, poluchennye blagodarya rabote proekta Hipparcos. V chastnosti, avtory opredelili momenty prohozhdeniya Solncem spiral'nyh rukavov. Pokazano, chto eto sovpadaet s holodnymi epohami v istorii zemnogo klimata. Avtory vidyat podtverzhdenie rabot, svyazannyh s vliyaniem potoka kosmicheskih luchei na formirovanie oblachnogo pokrova Zemli. miniobzor astro-ph/0503315 Astrofizicheskie nablyudeniya: linzirovanie i zatmeniya v teoriyah Einshteina (Astrophysical Observations: Lensing and Eclipsing Einstein's Theories) Authors: Charles L.
