    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.

    astro-ph/0412236 Neobychnye rentgenovskie tranzienty v centre Galaktiki (Unusual X-ray transients in the Galactic Centre)
    Authors: Masaaki Sakano et al.
    Comments: 9 pages, 5 figures, to appear in MNRAS, figures with full resolution are available at http://www.star.le.ac.uk/~mas/research/paper/#Sakano2004mnras

    Avtory dokladyvayut ob otkrytii dvuh neobychnyh rentgenovskih tranzientov. 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.
    Comments: 20 pages, 8 figures, accepted to ApJ

    V rezul'tate issledovaniya 36 blizkih malomassivnyh zvezd pyat' iz nih byli razresheny na dva komponenta (dve sistemy opisany vpervye). 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.

    Authors: Margarita Hernanz
    Comments: 14 pages, review paper for the conference 'The Astrophysics of Cataclysmic Variables and Related Objects', Strasbourg, France, 11-16 July 2004 (ASP Conference Series, Eds. J.M. Hameury and J.P. Lasota)

    Vse dostatochno horosho znayut, chto takoe novye zvezdy. 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.

    Osnovnaya tema obzora - ispol'zovanie dannyh po reliktovomu izlucheniyu v kosmologii. Kratko opisano chto i kak mozhno uznat' o nashei Vselennoi iz nablyudenii mikrovolnovogo fona, opisana standartnaya model' i rassmotreno, chto my mozhem ozhidat' v techenie blizhaishih 10 let v etoi oblasti astrofiziki.

    Authors: Stuart Samuel
    Comments: International Journal of Modern Physics D13 (2004) 1753-1770

    Eksperiment Kopeikina-Famolona eshe dolgo budet budorazhit' specialistov. Vot ocherednaya stat'ya, posvyashennaya emu. Dannaya rabota skepticheskogo plana: avtor pokazyvaet v chem, po ego mneniyu, Kopeikin byl neprav.


    astro-ph/0412404 Podhod, ob'yasnyayushii bol'shoe vremya ohlazhdeniya anomal'nyh rentgenovskih pul'sarov i istochnikov povtoryayushihsya gamma-vspleskov (An Approach to Explain the Long Cooling Times of Anomalous X-ray Pulsars and Soft Gamma Repeaters with the Neutrino Magnetic Moment)

    Authors: Liu Xuewen, Zheng Xiaoping, Hou Defu
    Comments: 10 pages, 2 figures

    Dve stat'i, svyazannye obshei tematikoi: izluchenie neitrino sil'nozamagnichennymi neitronnymi zvezdami.

    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).

    Ochen' korotkaya zametka, posvyashennaya evolyucii dvoinyh sverhmassivnyh chernyh dyr v centrah galaktik i ih vliyaniyu na razlichnye proyavleniya yadernoi aktivnosti. Avtor vydelyaet chetyre osnovnye stadii evolyucii takoi dvoinoi sistemy: ot ochen' shirokoi pary do sliyaniya. Na raznyh etapah zhizni dvoinoi mozhno ozhidat' razlichnye formy aktivnosti. Podrobnee o svoei rabote Andrei rasskazyvaet na konferencii v IKI.

    Summirovany ozhidaemye nauchnye rezul'taty ot raboty sputnika GAIA i provedeno korotkoe obsuzhdenie vliyaniya etih rezul'tatov na astronomiyu vcelom.


    astro-ph/0412492 Izbytok tranzientnyh rentgenovskih sistem v central'nom parseke Galaktiki (An Overabundance of Transient X-ray Binaries within 1 pc of the Galactic Center)
    Authors: M. 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. Antonelli et al., to be published with AIP. 10 pages,6 figures

    Daetsya obzor poslednih dannyh po rentgenovskim istochnikam v sharovyh skopleniyah. Osobyi upor sdelan na ul'trakompaktnye sistemy, obrazovanie kotoryh v obychnyh usloviyah galakticheskogo diska bylo by zatrudnitel'nym. Krome togo, rassmotreny sistemy maloi svetimosti, kolichestvo kotoryh rastet blagodarya novym teleskopam tipa Chandry.





    My budem starat'sya hotya by perechislit' interesnye (dlya shirokoi publiki) stat'i, poyavivshiesya v razdele physics (vklyuchaya cross-listing).
