Willman et al. Comments: 9 pages, 7 figures. MNRAS submitted Skol'ko sputnikov u nashei Galaktiki? Mlechnyi Put' - samoe plohoe mesto otkuda ih mozhno schitat': nekotorye ih nih zakryvayutsya diskom ili centrom, prichem opredelit' dolyu propushennyh ob'ektov tol'ko po sputnikam samoi nashei Galaktiki ochen' trudno. No mozhno posmotret' na blizkuyu galaktiku podobnogo tipa, naprimer na Tumannost' Andromedy (M31). V etom sluchae okazyvaetsya, chto my nedoschityvaemsya karlikovyh sputnikov Mlechnogo Puti v 1.5-2 raza.

Pello et al. Comments: 2004, A&A, Vol. 416, L35 Vozmozhno obnaruzhena ochen' dalekaya galaktika na krasnom smeshenii 10. Otmetim, chto vse-taki rezul'tat nuzhdaetsya v podtverzhdenii.

Sledstviem etoi gipotezy bylo sushestvovanie na nebe 6 par krugov diametrom primerno 70o, vdol' kotoryh anizotropiya relikta vedet sebya odinakovym dlya kazhdoi pary obrazom. Takie krugi uzhe iskali, no ne nashli (astro-ph/0310233). Avtory dannoi stat'i pokazyvayut, chto iz-za dvizheniya nablyudatelya otnositel'no reliktovogo izlucheniya (tochnee otnositel'no poverhnosti poslednego rasseyaniya) krugi okazyvayutsya iskazheny iz-za effekta Dopplera i aberracii sveta. Dlya Zemli eto iskazhenie sostavlyaet primerno 0.14o, sledovatel'no, metody vyyavleniya krugov, rabotayushie s maksimal'nym razresheniem, dostupnym WMAP (ili s eshe bolee detal'nymi kartami), davali by nevernyi rezul'tat.

Rassmatrivayutsya voprosy registracii neitrinnogo signala na Zemle na sushestvuyushih ustanovkah i vozmozhnost' na etoi osnove razlichit' te ili inye modeli neitronnyh zvezd. Registraciya neitrinnogo signala ot sverhnovoi 1987A na ustanovkah Kamiokande i IMB byla vozmozhna tol'ko na rannih etapah sushestvovaniya protoneitronnoi zvezdy (<10 s) i ne nakladyvalo ogranichenii na massu i svoistva neitronnoi zvezdy. Registraciya vspyshki sverhnovoi v centre nashei Galaktiki na sovremennyh ustanovkah (SNO, USO ili SuperKamiokande) pozvolit opredelit' massu neitronnoi zvezdy i opredelit' sostoyanie ee veshestva. miniobzor astro-ph/0403047 Mul'tiversnye kosmologicheskie modeli (Multiverse cosmological models) Authors: P.C.W.

Sledovatel'no, esli testy programmy proidut udovletvoritel'no, cherez nekotoroe vremya nado zhdat' novyh i interesnyh rezul'tatov v dannom napravlenii. !!! astro-ph/0403076 Priroda zatmenii v dvoinom pul'sare J0737-3039 (Nature of eclipses in binary pulsar J0737-3039) Authors: Maxim Lyutikov (McGill University, CITA) Comments: 25 pages, 10 figures. Submitted to MNRAS U nedavno otkrytogo "dvazhdy dvoinogo" pul'sara J0737-3039 (sm. astro-ph/0312071 i stat'yu na astronet.ru), tochnee u ego molodogo i medlenno vrashayushegosya (2.8 s) komponenta nablyudaetsya strannyi effekt: on izluchaet radioimpul's tol'ko na opredelnennyh orbital'nyh fazah, a v ostal'noe vremya on ne viden. V dannoi rabote predlozheno vozmozhnoe ob'yasnenie etogo effekta: ono sostoit vo vzaimodeistvii magnitosfery medlennogo pul'sara s relyativistskim vetrom ot millisekundnogo komponenta. Dannuyu ideyu illyustriruyut privedennye nizhe shemy, a za ostal'nymi detalyami pridetsya obrashat'sya k stat'e. astro-ph/0403170 Ohlazhdenie neitronnyh zvezd.

A vyvody takovy: poskol'ku krasnoe smeshenie galaktik izmereno po spektral'noi linii, kotoraya byla otozhdestvlena s Lα, to veshestvo na z=10 bylo uzhe ionizovano (reionizovano). V protivnom sluchae izluchenie v etoi linii bylo by polnost'yu poglosheno neitral'nym vodorodom, lezhashim na luche zreniya. obzor astro-ph/0403225 Obrazovanie i evolyuciya pervyh massivnyh chernyh dyr (The Formation and Evolution of the First Massive Black Holes) Authors: Zoltan Haiman, Eliot Quataert Comments: 39 pages, no figures, glava v knige Skoree vsego, pervye chernye dyry obrazovalis' na z>10 v nebol'shih oblastyah koncentracii temnogo veshestva (s massoi ~106Mo). Zatem oni rosli za schet sliyanii i akkrecii i prevratilis' v populyaciyu central'nyh ob'ektov yarkih kvazarov, a zatem kvazary pogasli, a chernye dyry (stavshie k tomu vremeni sverhmassivnymi) okazalis' v centrah galaktik. V obzore podrobno rassmatrivaetsya realistichnost' i vozmozhnye problemy dannogo scenariya, a takzhe fizicheskie processy na razlichnyh ego stadiyah. astro-ph/0403251 K voprosu ob otsutstvii teplovogo izlucheniya ot chernoi dyry XTE J1118+480 v spokoinom sostoyanii: ukazanie na sushestvovanie gorizont (On the Lack of Thermal Emission from the Quiescent Black Hole XTE J1118+480: Evidence for the Event Horizon) Authors: Jeffrey E.

Mori et al. Comments: 14 pages, 5 figures, accepted in ApJ Dlya izmereniya protyazhennosti atmosfery Titana (sputnika Saturna) byla primenena neobychnaya procedura. 5 yanvarya 2003 goda Titan pokryval Krabovidnuyu Tumannost'. Tumannost' vo vremya etogo sobytiya nablyudalas' s borta sputnika Chandra. Pri prohozhdenii Titana registrirovalas' "ten' pokrytiya", kotoraya obnaruzhivalas' do rasstoyanii 880+/-60 km ot poverhnosti sputnika. Eto pervoe izmerenie, kotoroe soglasuetsya s bol'shoi protyazhennost'yu atmosfery Titana, zaregistrirovannoi Voyadzherom (na drugih dlinah voln). Prohozhdenie Titana po Krabovidnoi Tumannosti.

Comments: 6 pages, 4 figures Evolyucionnyi populyacionnyi sintez odinochnyh zvezd ispol'zuetsya dlya modelirovaniya integral'nyh cvetov i spektrov galaktik, ne razreshaemyh na otdel'nye zvezdy. Dlya provedeniya podobnogo modelirovaniya ispol'zuyutsya setki evolyucionnyh trekov zvezd, rasschitannyh special'no dlya podobnogo primeneniya. Tochnosti podobnyh trekov ochen' veliki, oni dostigayut desyatyh dolei procenta. No pri provedenii podobnogo sinteza vsegda stoyal vopros, ne vnesut li tesnye dvoinye zvezdy, kotoryh v galaktikah po krainei mere desyat' procentov, sushestvennuyu pogreshnost'. Teper' na nego poluchen polozhitel'nyi otvet. Uchet populyacii dvoinyh zvezd delaet integral'nye cveta i spektry galaktik zametno bolee golubymi. Interpretaciya etih dannyh v ramkah tol'ko odinochnyh zvezd privodit k zavysheniyu vozrastov i metallichnosti populyacii.

Izluchenie, padayushee na poverhnost' normal'noi komponenty, mozhet na neskol'ko poryadkov prevoshodit' sobstvennuyu svetimost' zvezdy. V rezul'tate voznikaet samopodderzhivayushayasya akkreciya, kotoraya idet v sushestvenno bolee vysokom tempe, chem mogla by obespechit' termoyadernaya evolyuciya zvezdy. Pri etom vozmozhen kak stacionarnyi, tak i ciklicheskii rezhim, pri kotorom veshestvo vypadaet na kompaktnyi ob'ekt porciyami i vyzyvaet vspyshki zhestkogo izlucheniya.
