Comments: 12 pages, one figure (reduced resolution JPG posted), accepted for publication in the ApJ Letters S pomosh'yu poslednih dannyh nablyudenii i programmy, modeliruyushei evolyuciyu zvezd, udalos' dostatochno tochno opredelit' massu zvezdy, iz kotoroi obrazovalas' Sirius V - belyi karlik v pare s Siriusom A, kotoryi my vidim kak yarchaishuyu zvezdu nochnogo neba. Massa okazalas' 4.78-5.43 mass Solnca, a prevrashenie v belyi karlik sostoyalos' primerno 115-135 millionov let nazad. astro-ph/0507574 Poisk tochechnyh istochnikov kosmicheskih luchei sverhvysokih energii (Search for Point Sources of Ultra--High-Energy Cosmic Rays Above 10^19 eV Using a Maximum Likelihood Ratio Test) Authors: Stefan Westerhoff et al. Comments: 4 pages, 1 figure. To be presented at the 2005 ICRC in Pune, India, in August Ocherednoi otchet komandy HiRes po poisku tochechnyh istochnikov kosmicheskih luchei sverhvysokih energii. Napomnim, chto raznye gruppy po dannym raznyh eksperimentov (v pervuyu ochered' AGASA i HiRes) davali sovershenno raznye rezul'taty. Sama gruppa HiRes obychno daet nulevoi rezul'tat. Tak eto i na sei raz: nikakih ukazanii na nalichie tochechnyh istochnikov (tipa lacertid, naprimer) ne obnaruzheno. miniobzor astro-ph/0507582 Ukazaniya na fundamental'nyi predel massy zvezd po dannym o zvezdoobrazovanii v skopleniyah (Evidence for a fundamental stellar upper mass limit from clustered star formation, and some implications therof) Authors: Pavel Kroupa, Carsten Weidner Comments: 11 pages, invited review, to appear in Massive Star Birth, IAUSymp. 227, eds: R. Cesaroni et al Ochen' interesnyi obzor, posvyashennyi probleme verhnego predela na massy zvezd. Ukazhem na odin nablyudatel'nyi fakt, obsuzhdaemyi v obzore. Nablyudeniya skoplenii ukazyvayut na predel v 150 mass Solnca vne zavisimosti ot metallichnosti skopleniya. Ob'yasnenii takomu udivitel'nomu faktu net. astro-ph/0507593 Kollaps yader ochen' massivnyh zvezd (Core-Collapse Very Massive Stars: Evolution, Explosion, and Nucleosynthesis of Population III 500 -- 1000 $M_{\odot}$ Stars) Authors: T. Ohkubo et al. Comments: 46 pages, 45 figure files Dany rezul'taty raschetov kollapsa massivnyh zvezd populyacii III. Eto ob'ekty s massoi do 1000 mass Solnca, prakticheski lishennye tyazhelyh elementov. Pokazano, chto samye massivnye iz nih mogut davat' chernye dyry s massami poryadka 500 solnechnyh. miniobzor astro-ph/0507594 Astrofizika vysokih energii i Virtual'naya Observatoriya (High-energy Astrophysics and the Virtual Observatory) Authors: P. Padovani Comments: 12 pages, 3 figures, invited talk at the Workshop `Multifrequency Behaviour of High Energy Cosmic Sources'', Vulcano, Italy, May 2005, F. Giovannelli et al., in press Osnovnoe vnimanie udeleno evropeiskoi chasti Virtual'noi observatorii i primeneniyam Observatorii v astrofizike vysokih energii. Primery, na moi vzglyad, ne slishkom yarkie, no ubeditel'nye, tem bolee chto rech' idet o prototipe VO. nucl-th/0507055 Poverhnost' strannyh zvezd (The Strange Star Surface: A Crust with Nuggets) Authors: Prashanth Jaikumar, Sanjay Reddy, Andrew W. Steiner Comments: 4 pages, 2 figures Vozmozhno, chto strannye zvezdy eshe bolee neulovimy, chem eto schitalos' ranee. S 80-h godov bylo yasno, chto oni ochen' horosho maskiruyutsya pod obychnye neitronnye. Odnako nekotorye nadezhdy vozlagali na svoistva poverhnosti etih ob'ektov. Delo v tom, chto poverhnost' iz kvarkovogo veshestva budet nepohozhei na obychnuyu. V chastnosti, budut drugie mehanicheskie svoistva, drugaya teploprovodnost', i, glavnoe, k nei ne budet primenim eddingtonovskii predel svetimosti. V dannoi zhe rabote avtory stroyat model', v kotoroi poverhnost' kvarkovoi zvezdy (tochnee, ee kora) soderzhit kvarkovoe veshestvo v vide "samorodkov" (nuggets). V takom sluchae svoistva okazyvayutsya ochen' pohozhimi na svoistva obychnoi kory neitronnoi zvezdy. Esli eto i v samom dele tak, to vydelit' kvarkovye zvezdy budet eshe slozhnee. Pravda, ne dlya vseh tipov kvarkovyh zvezd takoe opisanie primenimo. Naprimer, dlya zvezd, veshestvo kotoryh nahoditsya v t.n. CFL (color flavor locked) faze, dannyi tip kory nevozmozhen. astro-ph/0507651 Gamma-luchi ot odnostoronnih vzryvov sverhnovyh (Gamma-Rays from Single Lobe Supernova Explosions) Authors: A. L. Hungerford, C. L. Fryer, G. M. Rockefeller Comments: 39 pages, 18 figures, submitted to ApJ Version with high resolution figures can be found at this http URL Poslednie raschety vzryvov sverhnovyh, provodimye razlichnymi gruppami, ukazyvayut na sushestvennuyu stepen' asimmetrii. V dannoi rabote avtory rassmatrivayut posledstviya takoi asimmetrii, fokusiruyas' na svoistvah gamma-izlucheniya, voznikayushego v rezul'tate "odnostoronnih" vzryvov. Rech' idet ne ob izluchenii, voznikayushem pryamo v moment vspyshki. V rezul'tate asimmetrichnogo vzryva proishodit odnostoronnii vybros veshestva, kotoroe vposledstvii budet porozhdat' gamma-luchi. Sootvetstvenno, rassmatrivayutsya svoistva ostatkov SR1987A i Cas A. astro-ph/0507655 Smeshenie Solnca ot galakticheskoi ploskosti po dannym spektroskopicheskih parallaksov 2400 OV zvezd (The Sun's displacement from the galactic plane from spectroscopic parallaxes of 2400 OB stars) Authors: B. Cameron Reed Comments: Submitted to JRASC Izvestno, chto Solnce nahoditsya ne tochno v ploskosti Mlechnogo Puti. Tochnoe znachenie etogo nebol'shogo smesheniya predstavlyaet bol'shoi interes, t.k. ispol'zuetsya dlya samyh raznyh rabot. Avtor utochnyaet znachenie etoi vazhnoi velichiny, ispol'zuya dannye po 2397 massivnym zvezdam v 1.2 kpk ot nas, rasstoyaniya do kotoryh opredeleny po spektram. Poluchennoe znachenie - 19.5 +/- 2.2 pk - nahoditsya v horoshem soglasii s bolee rannimi ocenkami. obzor gr-qc/0507101 Chernye dyry i fundamental'naya fizika (Black holes and fundamental physics) Authors: Jose P.

P. M. Sa' et al; 20 pages Obzor, celikom posvyashennyi fizike chernyh dyr. Stat'ya napisana ochen' populyarnym yazykom, poetomu razobrat'sya vo vsem dostatochno legko. Avtor na pal'cah ob'yasnyaet vse osnovnye ponyatiya, svyazannye s opisyvaemym predmetom. astro-ph/0507679 >Massivnye skopleniya galaktik i proishozhdenie kosmicheskih luchei sverhvysokih energii (Massive galaxy clusters and the origin of Ultra High Energy Cosmic Rays) Authors: Elena Pierpaoli, Glennys Farrar Comments: 5 pages Ocherednaya popytka vyyasnit' korreliruyut li kosmicheskie luchi sverhvysokih energii hot' s chem-nibud'. Na etot raz rassmotrena korrelyaciya s bogatymi skopleniyami galaktik, i poluchen ne nulevoi rezul'tat. T.o., zaklyuchayut avtory, kosmicheskie luchi sverhvysokih energii svyazany so skopleniyami ili s kakimi-to ob'ektami, vhodyashimi v skopleniya. Zametim, odnako, chto statisticheskaya znachimost' rezul'tata ne ochen' velika, a, krome togo, iskat' korrelyacii s netochechnymi ob'ektami slozhnee. Tak chto radovat'sya rano, neobhodimo, chtoby drugie gruppy proverili etot rezul'tat. obzor astro-ph/0507686 Turbulenciya i magnitnye polya v astrofizicheskoi plazme (Turbulence and Magnetic Fields in Astrophysical Plasmas) Authors: A.

Detal'no rassmotrena plazma solnechnogo vetra i mezhgalakticheskaya sreda v skopleniyah. astro-ph/0507687 "Nedostayushie" MZO v central'nom parseke Galaktiki: ukazaniya na zvezdoobrazovanie v massivnom akkrecionnom diske (The "missing" YSOs in the central parsec of the Galaxy: evidence for star formation in a massive accretion disk and a top-heavy IMF) Authors: Sergei Nayakshin, Rashid Sunyaev Comments: submitted to MNRAS, 5 pages, no figures MZO - molodye zvezdnye ob'ekty. Stalo byt', rech' idet ob obrazovanii zvezd v centre nashei Galaktiki. Klyuchevoi vyvod avtorov sostoit v tom, chto oni polagayut MZO, obnaruzhennye vblizi Sgr A*, pervym pryamym primerom zvezdoobrazovaniya v massivnom diske, okruzhayushem sverhmassivnuyu chernuyu dyru. O massivnyh zvezdnyh skopleniyah v central'noi oblasti Mlechnogo Puti mozhno prochest' v stat'e astro-ph/0507693. astro-ph/0507692 Gravitacionnaya otdacha slivayushihsya chernyh dyr (Gravitational Recoil of Inspiralling Black-Hole Binaries to Second Post-Newtonian Order) Authors: Luc Blanchet, Moh'd S.

Will Comments: 18 pages, 1 figure, submitted to The Astrophysical Journal Okolo goda nazad aktivno obsuzhdalis' novye raschety po gravitacionnoi otdache, voznikayushei pri sliyanii dvuh chernyh dyr. Osnovnym rezul'tatom effekta sluzhit priobretenie poluchivsheisya chernoi dyroi lineinogo momenta (t.e., poprostu govorya, razgon). V obsuzhdaemoi stat'e predstavleny novye raschety, vklyuchayushie dopolnitel'nye chleny.
