Koerding, E. Colbert, H. Falcke Comments: Accepted for publication in A&A, 11 pages, 4 figures Avtory proveli radiomonitoring devyati blizhaishih ul'tramoshnyh rentgenovskih istochnikov (UMI) s pomosh'yu VLA. Ni postoyannogo, ni vspyshechnogo radioizlucheniya ot UMI zaregistrirovano ne bylo (obnaruzhennoe izluchenie dvuh istochnikov v M82 skoree vsego svyazano s ostatkami sverhnovyh). V principe rezul'taty nablyudenii ne pozvolyayut vybrat' odnu iz dvuh osnovnyh gipotez, ob'yasnyayushih prirodu UMI (akkreciya na chernye dyry promezhutochnyh mass ili zhe akkreciya na chernye dyry zvezdnyh mass s obrazovaniem relyativistskih dzhetov). Odnako takie nablyudeniya vazhny, mozhet byt' v dal'neishem avtoram povezet bol'she, i ih rezul'taty smogut pomoch' v vybore modeli dlya UMI. astro-ph/0502266 Rezhim propellera pri diskovoi akkrecii na bystrovrashayushuyusya zamagnichennuyu zvezdu (The Propeller Regime of Disk Accretion to a Rapidly Rotating Magnetized Star) Authors: Marina M. Romanova et al. Comments: 5 pages with 4 figures, LaTeX, macros: emulapj.sty, avi movies are available at http://www.astro.cornell.edu/us-russia/disk_prop.htm; Journal-ref: ApJ Letters, 616, L151-L154, 2004 Chestno govorya, vsegda nravilis' kartinki i fil'my, demonstriruyushie diskovuyu akkreciyu. Rassmotren rezhim propellera pri diskovoi akkrecii na zamagnichennuyu zvezdu. Rezul'taty mogut primenyat'sya kak dlya akkrecii na neitronnye zvezdy i belye karliki, tak i dlya issledovaniya zvezd tipa T Tel'ca. Na pervoi serii risunkov pokazano, kak izmenyaetsya konfiguraciya magnitnogo polya. Na levom risunke (T=0, vremya otschityvaetsya v uslovnyh edinicah, sootvetstvuyushih odnomu oborotu s keplerovskoi skorost'yu na rasstoyanii 2.86 radiusa zvezdy) pokazana nachal'naya konfiguraciya polya. Zatem nachinaetsya raschet, i vidno, kak silovye linii formiruyut "magnitnye bashni". V nizhnei chasti dano uvelichennoe izobrazhenie linii vblizi diska dlya T=70. Na vtoroi serii risunkov prodemonstrirovano, chto nesmotrya na to, chto sistema nahoditsya na stadii propellera, kogda bystrovrashayusheesya magnitnoe pole prepyatstvuet proniknoveniya veshestva na poverhnost' zvezdy, nekotoraya akkreciya tem ne menee vozmozhna.

M. Gutierrez, M. Lopez-Corredoira Comments: 9 pages, Accepted for publication in ApJ Letters Nadeemsya, chto s samimi ul'tramoshnymi istochnikami nashi chitateli uzhe horosho znakomy (ili po stat'e na Astronete, ili po peredache na radio Svoboda). Vot novye rezul'taty. Avtory rassmatrivayut vopros o tom, chto mnogie iz UMI mogut yavlyat'sya fonovymi dalekimi aktivnymi yadrami galaktik. Eto osobenno aktual'no dlya ob'ektov v ellipticheskih galaktikah, a takzhe dlya istochnikov na okrainah galaktik vne oblastei moshnogo zvezdoobrazovaniya. Rassmatrivaetsya shest' istochnikov, dlya kotoryh polucheny horoshie opticheskie spektry. Vse shest' okazalis' dalekimi kvazarami. Vse shest' lezhat dostatochno daleko ot centrov svoih galaktik. Rezul'taty nahodyatsya v horoshem soglasii s bolee rannimi ocenkami. T.o., kak i predpolagalos', dlya UMI, lezhashih vne vydelennyh oblastei (spiral'nye rukava, oblasti zvezdoobrazovaniya, sharovye skopleniya i t.p.) velika dolya fonovyh. astro-ph/0502297 Gamma-vspleski ot kvarkovyh zvezd (Gamma-Ray Bursts from quark stars) Authors: B. Paczynski, P. Haensel Comments: 4 pages, submitted to MNRAS (Letters) Prevrashenie neitronnoi zvezdy v kvarkovuyu soprovozhdaetsya vydeleniem kolossal'noi energii, sravnimoi tol'ko so vzryvom sverhnovoi ili so sliyaniem dvuh kompaktnyh ob'ektov. Poetomu uzhe dostatochno davno obsuzhdaetsya vozmozhnaya svyaz' gamma-vspleskov s kvarkovymi zvezdami. Chto zhe novogo predlagayut avtory obsuzhdaemoi stat'i? Novizna svyazana vot s chem. Poyavlyayutsya ukazaniya na to, chto sredi obychnyh (dlinnyh) gamma-vspleskov pryachutsya dva raznyh tipa sobytii. Odin tip svyazan s bolee slabymi vspleskami, proishodyashimi bez obrazovaniya ul'tra-relyativistskih dzhetov. Vtoroi - soprovozhdaetsya poyavleniem takih obrazovanii. Oba svyazany so sverhnovymi tipa Ic, a raznica mozhet ob'yasnyat'sya tem, chto posle vzryva formiruyutsya raznye tipy kompaktnyh ob'ektov. Avtory polagayut, chto vtoroi tip vspleskov svyazan s tem, chto posle vzryva sverhnovoi i obrazovaniya protoneitronnoi zvezdy proishodit formirovanie kvarkovogo ob'ekta. Osnovnoe preimushestvo oni vidyat ne v dopolnitel'noi energetike, a v tom, chto poyavlenie poverhnosti kvarkovoi zvezdy mozhet privesti k tomu, chto vo vneshnee prostranstvo vyletyat tol'ko elektrony, pozitrony, neitrino, fotony, no nikak ne bariony! T.e. poverhnost' budet rabotat' kak svoeobraznaya membrana. Avtory polagayut, chto rabotayushii seichas na orbite sputnik Swift smozhet dat' reshayushuyu informaciyu dlya podtverzhdeniya sushestvovaniya dvuh tipov klassicheskih gamma-vspleskov. Krome togo, hotya napryamuyu vryad li udastsya prodemonstrirovat' obrazovanie kvarkovoi zvezdy, tem ne menee mozhno nadeyat'sya na to, chto novaya informaciya proyasnit chto-to i v etom voprose. astro-ph/0502312 Temnoe vodorodnoe oblako v skoplenii v Deve (A Dark Hydrogen Cloud in the Virgo Cluster) Authors: Robert Minchin et al. Comments: Accepted to ApJL, 12 pages Vazhnoe otkrytie sdelali britanskie astronomy (populyarnoe izlozhenie sm. na saite Gazeta.Ru). Neskol'ko let nazad imi byl obnaruzhen lyubopytnyi ob'ekt v skoplenii galaktik v Deve. Vse eto vremya provodilis' povtornye nablyudeniya i ih analiz. V itoge otkryta "temnaya galaktika". Zametim, chto rech' ne idet o dalekoi protogalaktike. Eto blizkii ob'ekt v "nashem" skoplenii galaktik. Sovremennye teorii obrazovaniya krupnomasshtabnoi struktury predskazyvayut poyavlenie znachitel'nogo chisla temnyh galaktik. Eto galo temnoi materii, plotnost' gaza v kotoryh nedostatochno velika dlya obrazovaniya zvezd (v etom-to i sostoit prichina ih "temnoty"). Odnako, kak yasno, obnaruzhit' "temnuyu galaktiku v temnom kosmose" nelegko, dazhe esli ih tam mnogo. I vot udalos' pokazat', chto takoi ob'ekt naiden. Da, ne zrya ob etoi rabote napisali zametku v Nature. Pozhalui, osnovnoe znachenie etoi raboty sostoit v tom, chto podtverzhdaetsya odno iz vazhnyh predskazanii sovremennoi teorii obrazovaniya galaktik. Znachit, my idem v pravil'nom napravlenii. obzor astro-ph/0502328 Inflyacionnaya kosmologiya: issledovanie vselennoi ot samyh malen'kih do samyh bol'shih masshtabov (Inflationary Cosmology: Exploring the Universe from the Smallest to the Largest Scales) Authors: Alan H. Guth, David I. Kaiser Comments: 16 pages, 4 figures, written for "Einstein's Legacy" issue of Science magazine; Science 307, 884-890 (11 Feb 2005) Obzory, napisannye dlya zhurnala Science, otlichaet nauchnaya strogost' vmeste s dostupnost'yu lyudyam, neyavlyayushimsya uzkimi specialistami v dannoi oblasti. Dannaya stat'ya posvyashena inflyacionnoi kosmologicheskoi modeli. Odin iz avtorov - Alan Gus - kak izvestno, yavlyaetsya odnim iz krestnyh otcov etoi teorii. S momenta, kogda model' byla predlozhena (nachalo 80-h) ona preterpela ser'eznye izmeneniya. O sovremennom sostoyanii del (vklyuchaya nablyudatel'nye testy) mozhno prochest' v obzore. astro-ph/0502329 Gigantskaya vspyshka ot SGR1806-20 s prilozheniem k korotkim gamma-vspleskam (A tremendous flare from SGR1806-20 with implications for short-duration gamma-ray bursts) Authors: Hurley et al. Comments: 27 pages, 5 figures. Submitted to Nature 27 dekabrya byla zaregistrirovana samaya moshnaya vspyshka ot istochnika povtoryayushihsya gamma-vspleskov. Za doli sekundy vydelilos' okolo 1046 ergov (Solnce izluchaet stol'ko za 10 000 let). Potok energii na Zemle sostavil okolo 1 erga na kvadratnyi santimetr. Napomnim, chto istochniki myagkih povtoryayushihsya gamma-vspleskov (MPG) byli otkryty v 1979 godu, v pervuyu ochered' blagodarya otechestvennyh sputnikam Venera i Prognoz na priborah razrabotannoi gruppoi Mazeca. Sovremennye teorii risuyut MPG kak sil'no zamagnichennye neitronnye zvezdy - magnitary. Perestroiki magnitnogo polya i privodyat k vspyshkam. Chetkoi odnoznachnoi modeli vspleskov poka net. O novyh teoriyah sm. svezhuyu zametku astro-ph/0502349. Vspyshki byvayut treh osnovnyh vidov: slabye, promezhutochnye, gigantskie. Poslednyuyu vspyshku uzhe vydelili v otdel'nyh klass gipervspyshek. V stat'e predstavleny osnovnye rezul'taty nablyudenii. Takzhe privedeny interesnye rassuzhdeniya, kasayushiesya vozmozhnoi svyazi takih vspyshek s podklassom zhestkih korotkih gamma-vspleskov. Delo v tom, cho sputnik tipa CGRO (pribor BATSE) mog by videt' takoi vsplesk s rasstoyaniya do 50 Mpk. Znachit, esli uzh v nashei Galaktike za 30 let nablyudenii my uvideli odnu takuyu vspyshku (kstati, rasstoyanie do MPG - 15 kpk), to iz ob'emy, ogranichennogo 50 Mpk BATSE mog by zaregistrirovat' 1-2 sotni takih yavlenii. Zametim, chto razumno predpolozhit' sleduyushee, t.k. magnitary eto ochen' molodye i korotkozhivushie ob'ekty, to osnovnoi vklad v proizvodstvo takih gipervspyshek budut vnosit' galaktiki s vysokim tempom zvezdoobrazovaniya i vysokim tempom vspyshek sverhnovyh. Etomu posvyashena korotkaya zametka odnogo iz avtorov obzorov. Privedem takzhe ssylki na ryad drugih svezhih rabot, poyavivshihsya v Arhive v svyazi s gigantskoi vspyshkoi magnitara. Vsplesk byl zaregistrirovan neskol'kimi kosmicheskimi apparatami, v tom chisle i rossiiskim Koronas-F (detektor Gelikon), a takzhe rossiiskim priborom Konus na amerikanskom sputnike Wind. Apparatura Koronas-F smogla dazhe zafiksirovat' izluchenie vspyshki, otrazhennoe ot Luny. Eto pervyi podobnyi sluchai. Ob etom - v stat'e Mazeca i dr. Rezul'taty moshnoi vspyshki byli obnaruzheny i v radiodiapazone. Ob etom mozhno prochest' v stat'yah astro-ph/0502393 i astro-ph/0502428. Stat'ya astro-ph/0502428 interesna eshe i tem, chto avtory osparivayut tradicionnuyu ocenku rasstoyaniya do istochnika vspleska. Vmesto obychnyh 15 kpk oni predlagayut velichinu 6-10 kpk. Eto, razumeetsya, privodit k izmeneniyu ocenki energetiki vspleska, odnako, dazhe ee korrekciya v 3-5 raz v storonu umen'sheniya ostavlyaet vspyshku samoi moshnoi iz nablyudavshihsya ot MPG. Rezul'taty rentgenovskih nablyudenii v period, predshestvovavshii vspyshke, summirovany v stat'e A XMM-Newton View of the Soft Gamma-ray Repeater SGR 1806--20: Long Term Variability in the pre-Super Giant Flare Epoch. Poslednyaya iz poyavivshihsya v fevrale statei na temu vspyshki SGR 1806-20 posvyashena nablyudeniyam na pribore SPI na bortu sputnika Integral. Avtory v osnovnom rasskazyvayut o nablyudeniyah hvosta vspleska (napomnim, chto zhestkie gigantskie vspyshki soprovozhdayutsya "hvostom" bolee myagkogo pul'siruyushego izlucheniya, period pul'sacii raven periodu vrasheniya neitronnoi zvezdy). Svyazano eto s bol'shoi moshnost'yu vspleska: t.k. Integral obladaet priborami s ochen' bol'shoi sobirayushei ploshad'yu, to potok fotonov byl nastol'ko velik, chto na vremya osnovnogo pika sputnik prosto "oslep".
