Obzory preprintov astro-ph Vypusk N94 astro-ph za 13 - 21 dekabrya 2004 goda: izbrannye stat'i Goryachie temy nedeli Zvezdoobrazovanie na bol'shih krasnyh smesheniyah Za podotchetnyi period poyavilos' neskol'ko privlekshih nashe vnimanie statei, svyazannyh so zvezdoobrazovaniem na bol'shih krasnyh smesheniyah. Nachnem s raboty Cosmic Infrared Background and Early Galaxy Evolution. Eto bol'shoi (97 stranic) obzor, posvyashennyi infrakrasnomu fonovomu izlucheniyu. Svyazano ono s summarnym vkladom mnozhestva galaktik. V osnovnom eto ob'ekty na bol'shih krasnyh smesheniyah. Poetomu odnim iz vazhneishih ingredientov, neobhodimyh dlya ob'yasneniya svoistv IK-fona, yavlyaetsya znanie tempa zvezdoobrazovaniya vo Vselennoi. Stat'ya Starbursts at z >~6: from the present to Herschel and ALMA rasskazyvaet o vozmozhnosti nablyudenii galaktik na bol'shih krasnyh smesheniyah na teleskopah Herschel i ALMA. Avtory polagayut, chto v sovsem nedalekom budushem my poluchim novuyu sushestvennuyu informaciyu o samyh pervyh galaktikah. (sm. takzhe stat'yu teh zhe avtorov po toi zhe tematike: Stellar populations and Lyman-alpha emission from lensed z>6 galaxies). Samye pervye zvezdy otnosyat k t.n. populyacii III (Population III). Eto byli massivnye zvezdy, sostoyashie v osnovnom iz vodoroda i geliya (metallichnost' ih chrezvychaino mala). Imenno vzryvy etih ob'ektov obogatili nashu Vselennuyu tyazhelymi elementami. O chisle i vozmozhnostyah nablyudeniya pervyh sverhnovyi idet rech' v stat'e The Number and Observability of Population III Supernovae at High Redshifts. Krome svoih obychnyh proyavlenii sverhnovye dayut gravitacionnyi vsplesk. V stat'e Stochastic Gravitational Wave Background from Cosmological Supernovae avtory ocenivayut summarnyi vklad vseh sverhnovyh vo Vselennoi v gravitacionno volnovoi fon.

Neobychnost' svyazana v pervuyu ochered' s nevysokoi maksimal'noi svetimost'yu etih istochnikov: poryadka 5 1034 erg/s. Po-mneniyu avtorov ni odin iz izvestnyh tipov istochnikov ne mozhet ob'yasnit' eti dva. astro-ph/0412240 Otkrytie dvuh ochen' malomassivnyh dvoinyh (Discovery of Two Very Low-Mass Binaries: Final Results of an Adaptive Optics Survey of Nearby M6.0-M7.5 Stars) Authors: Nick Siegler et al.

Sistemy okazalis' dostatochno tesnymi. Dannyi rezul'tat podtverzhdaet, chto vo-pervyh, chem men'she massa komponent, tem men'she bol'shaya poluos' (v srednem, konechno), a vo-vtoryh, dolya dvoinyh sredi malomassivnyh zvezd men'she, chem sredi ih bolee massinyh sorodichei. miniobzor astro-ph/0412294 Obzor oborudovaniya VLBI (A Review of VLBI Instrumentation) Authors: W.

Napomnim, tem ne menee, chto eto dvoinye sistemy s belymi karlikami, i vzryv proishodit imenno na poverhnosti karlika. V etom nebol'shom obzore opisany poslednie dostizheniya v izuchenii novyh. Osoboe vnimanie avtor udelyaet nukleosintezu, proishodyashemu vo vremya vspyshek. astro-ph/0412350 Vozmozhnaya registraciya M31* na Chandre (A Possible Detection of M31* with Chandra) Authors: M.R. Garcia et al. Comments: 14 pages, 5 figures, submitted to ApJ Veroyatno, chto na sputnike Chandra udalos' zaregistrirovat' rentgenovskoe izluchenie ot sverhmassivnoi chernoi dyry v centre Tumannosti Andromedy. Svetimost' (kak i v sluchae nashei Galaktiki) okazalas' ochen' mala - okolo 3 1035 erg/s. Poetomu dostovernost' obnaruzheniya nevysoka. Neobhodimy bolee dlitel'nye nablyudeniya, chem predstavlennye v dannoi stat'e. miniobzor astro-ph/0412354 Ot COBE do WMAP (From COBE to WMAP: A Decade of Data Under Scrutiny) Authors: Louise M.

Avtory pervoi stat'i pytayutsya ob'yasnit', pochemu magnitary dolzhny byt' goryachimi. Oni polagayut, chto nalichie u neitrino nebol'shogo magnitnogo momenta privedet v dlinnym vremenam ohlazhdeniya sil'nozamagnichennyh zvezd. Vo vtoroi stat'e situaciya pryamo protivopolozhna: avtory pokazyvayut, chto strannye zvezdy s bol'shim magnitnym polem budut ostyvat' bystro. Konechno, osnovnye vyvody dvuh statei drug drugu ne protivorechat, no dlya ob'yasneniya prirody nablyudaemyh magnitarov (naprimer, v istochnikah povtoryayushihsya gamma-vspleskov i v anomal'nyh rentgenovskih pul'sarah) dolzhno podhodit' tol'ko chto-to odno (ili ni odnogo). astro-ph/0412416 Sliyaniya dvoinyh sverhmassivnyh chernyh dyr v kontekste evolyucii galaktik (Mergers and binary systems of SMBH in the contexts of nuclear activity and galaxy evolution) Authors: A.P.

P. Muno et al. Comments: 4 pages, including 2 figures (one color). Submitted to ApJ Letters Eshe 8 let nazad my obsuzhdali obilie rentgenovskih ischtonikov v centre Galaktiki, v chastnosti nashi raschety ukazyvali na to, chto osobenno mnogo dolzhno byt' tam rentgenovskih tranzientov. Pravda, my obsuzhdali ne central'nyi parsek, a bolee shirokuyu oblast'. Tem ne menee priyatno videt', chto kolichestvo otkryvaemyh tranzientov v central'noi chasti Galaktiki vse rastet i rastet. Avtory dokladyvayut ob otozhdestvlenii semi tranzientov vnutri 23 parsek ot galakticheskogo centra. Krome gipotezy o tom, chto vse eti istochniki pryamo tam i obrazovalis', avtory rassmatrivayut vozmozhnost' razrusheniya krupnogo skopleniya zvezd, vletevshego v central'nuyu oblast' nashei Galaktiki. miniobzor astro-ph/0412524 Rentgenovskie istochniki v sharovyh skopleniyah (X-ray sources in globular clusters) Authors: Frank Verbunt Comments: Invited review in: "Interacting binaries", July 4-10 Cefalu, eds.
