Smith et al. Comments: 9 pages, 2 figures, submitted to PRD Rassmotreny effekty, svyazannye s poyavleniem dopolnitel'nyh chlenov v uravneniyah OTO. Konkretno, rassmotrena t.n. gravitaciya Cherna-Simonsa. Takie modifikacii voznikayut v teorii strun. Rezul'taty raschetov sravnivayutsya s dannymi po povedeniyu sputnikov, chto pozvolyaet dat' ogranicheniya na parametry teorii. arxiv:0708.0002 1E 1547.0-5408: izluchayushii v radio magnitar s periodom vrasheniya 2 sekundy (1E 1547.0-5408: a radio-emitting magnetar with a rotation period of 2 seconds) Authors: F. Camilo et al. Comments: 4 pages, Accepted for publication in ApJ Letters Navstrechu 40-letiyu otkrytiya radiopul'sarov Otkryt ochen' interesnyi istochnik. Sperva on byl obnaruzhen v rentgenovskom diapazone. Togda zhe zapodozrili, chto eto mozhet byt' magnitar (istochnik nahoditsya v ostatke sverhnovoi). Potom udalos' uvidet' radioizluchenie i ustanovit' period - dve sekundy. Zatem byla izmerena pervaya proizvodnaya perioda (vrashenie neitronnoi zvezdy zamedlyaetsya, t.k. ona sil'no zamagnichena). Po zamedleniyu vrasheniya mozhno ocenit' pole - ono okazalos' ravnym 2 1014 Gauss. Poskol'ku na staryh izobrazheniyah (v rentgene) istochnik ne byl obnaruzhen, to pohozhe, chto eto vtoroi tranzientnyi magnitar (posle XTE J1810-197). katalog arxiv:0708.0030 Katalog fotometricheskih krasnyh smeshenii galaktik v shestom relize Sloanovskogo cifrovogo obzora neba (A Galaxy Photometric Redshift Catalog for the Sloan Digital Sky Survey Data Release 6) Authors: Hiroaki Oyaizu et al. Comments: 16 pages, 12 figures Predstavlen katalog krasnyh smeshenii i ego opisanie dlya primerno 77 millionov galaktik v Sloanovskom obzore. Konechno, fotometricheskoe opredelenie krasnyh smeshenii ne slishkom tochnoe, no sravnenie, provedennoe avtorami, pokazyvaet, chto v srednem oshibka priemlema. arxiv:0708.0123 SuperAGILE: pribor na sputnike AGILE, stroyashii izobrazheniya v zhestkom rentgenovskom diapazone (SuperAGILE: the hard X-ray Imager for the AGILE space mission) Authors: M. Feroci, et al. Comments: Nucl. Instr. and Meth. A, in press. Dano opisanie odnogo iz priborov ital'yanskogo sputnika AGILE, rabotayushego seichas na orbite (zapushen 23 aprelya etogo goda). Eto rentgenovskii detektor s kodirovannoi apperturoi, chto pozvolyaet "zadeshevo" stroit' izobrazheniya v zhestkom rentgene (razreshenie okolo 6 uglovyh minut v diapazone 15-45 keV pri shirokom pole zreniya - okolo steradiana). obzor arxiv:0708.0134 Fizika na LHC i kosmologiya (LHC Physics and Cosmology) Authors: Nikolaos E. Mavromatos Comments: 49 pages Latex, 25 EPS figures incorporated, uses special macros. Lectures presented at the Lake Louise Winter Institute 2007 (Lake Louise (Canada), February 19-24 2007) Bol'shoi obzor po kosmomikrofizike i rodstvennym temam. Posle vvodnoi chasti avtor rassmatrivaet, kak astrofizicheskie nablyudeniya mogut dat' ogranicheniya na fizicheskie teorii, i naoborot, kak novye dannye LHC smogut ogranichit' modeli, ispol'zuemye v astrofizike. arxiv:0708.0146 Chast' Merkuriya, kotoruyu ne videl Mariner 10 (A Side of Mercury Not Seen By Mariner 10) Authors: Gerald Cecil, Dmitry Rashkeev Comments: 7 pages, 4 PDF figures, pdfLaTeX, scheduled for Nov. Astronomical Journal Predstavleny rezul'taty s'emki s Zemli toi chasti Merkuriya, kotoraya ne byla otkartografirovana s Marinera 10. S'emka velas' na teleskope SOAR. Populyarnoe izlozhenie mozhno pochitat' zdes'. obzor arxiv:0708.0148 Modelirovanie povedeniya akkrecionnyh techenii v rentgenovskih dvoinyh (Modelling the behaviour of accretion flows in X-ray binaries) Authors: Chris Done, Marek Gierlinski, Aya Kubota Comments: 76 pages, accepted for publication in Astronomy and Astrophysics Reviews Bol'shoi podrobnyi obzor. Prichinoi dlya ego napisaniya posluzhil rost dannyh po tesnym dvoinym sistemam s kompaktnymi ob'ektami. Blagodarya mnogovolnovym nablyudeniyam - ot radio do gamma - udaetsya poluchat' dannye o povedenii i diskov, i dzhetov. Chto, v svoyu ochered', pozvolyaet stroit' modeli, v kotoryh zavyazana evolyuciya diska i dzheta. arxiv:0708.0226 GRB070610: lyubopytnyi galakticheskii tranzient (GRB070610 : A Curious Galactic Transient) Authors: M. M. Kasliwal et al. Comments: Submitted to ApJ, 17 pages, 11 figures, 5 tables 10 iyunya etogo goda sputnik SWIFT uvidel ocherednoi gamma-vsplesk. Nu uvidel - i uvidel. On ih chasto vidit, dlya togo i zapuskali. No vse ne tak prosto. Vozmozhno, chto my imeem delo s interesnym otkrytiem. Sputnik SWIFT neset na bortu pribory, pozvolyayushie opredelyat' polozhenie vspleska s dostatochno vysokoi tochnost'yu (neskol'ko uglovyh minut). Posle vspleska, dlivshegosya 5 sekund (normal'nyi vsplesk, klassificiruemyi kak "dlinnyi") v toi oblasti, iz kotoroi prishel vsplesk udalos' uvidet' peremennyi rentgenovskii istochnik. Opticheskie nablyudeniya etoi oblasti pokazali, chto spektr pohozh na spektr zvezdy klassa K (eto mozhet byt' sub-gigant ili karlik, t.e. obychnaya zvezda glavnoi posledovatel'nosti). Vse eto govorit o tom, chto my vidim tesnuyu dvoinuyu sistemu, skoree vsego s chernoi dyroi. Esli eta sistema imeet otnoshenie k vsplesku, to eto ochen' vazhnyi rezul'tat! Eto oznachaet, chto dvoinye chernye dyry (v pare s malomassivnym kompan'onom) mogut pokazyvat' ochen' interesnyi tip aktivnosti, kotoryi "podmeshivaetsya" k obychnym gamma-vspleskam!

Novye sputniki pozvolyayut poluchat' ochen' interesnye dannye (napomnyu, chto samoe sil'no svidetel'stvo sushestvovaniya temnoi materii polucheno s ispol'zovaniem rentgenovskih dannyh po skopleniyam). Krome togo, planiruyutsya novye instrumenty (naprimer, eROSITA na rossiiskom Spektre-RG). Obzor rasskazyvaet o tom, chto sdelano, i pochemu eto interesno. Voobshe, skopleniya galaktik seichas prityagivayut vnimanie issledovatelei.

Rech' idet ob interesnoi koncepcii "nechastic". V dannoi zhe stat'e avtor rassmatrivaet, kakie ogranicheniya na etu model' mogut dat' astrofizicheskie dannye, i chto tut mozhno voobshe ozhidat'. arxiv:0708.0626 Sinhrotronnaya sverhobolochka v galaktike IC10: ostatok gipernovoi? (A synchrotron superbubble in the IC 10 Galaxy: a hypernova remnant?) Authors: T.A. Lozinskaya, A.V. Moiseev Comments: 4 pages, 3 EPS figures, Accepted to MNRAS (in Letters) Vozmozhno, chto udalos' identificirovat' ostatok gipernovoi! Pokazano, chto sverhobolochka v galaktike IC10 veroyatnee vsego byla sformirovana za schet odnogo sil'nogo vzryva. arxiv:0708.0834 TrES-4: Tranzitnyi goryachii yupiter ochen' maloi plotnosti (TrES-4: A Transiting Hot Jupiter of Very Low Density) Authors: Georgi Mandushev et al. Comments: 5 pages Otkryta ocherednaya ekzoplaneta. Interes sostoit v tom, chto ona pobila odin iz rekordov. TrES-4 - eto planeta, prohodyashaya po disku svoei zvezdy (s tochki zreniya zemnogo nablyudatelya). Period obrasheniya vokrug zvezdy ochen' korotkii: 3.55 dnei. Zvezda chut' massivnee (a znachit bol'she i goryachee) chem Solnce. Neudivitel'no, chto planeta ot etoi pechki "puhnet". Radius planety primerno v 1.7 raza bol'she yupiterianskogo, a massa chut' men'she, chem u Yupitera. V itoge, my imeem planetu s ochen' nizkoi plotnost'yu. Eto rekord. Avtory polagayut, chto eto otkrytie stavit nekotorye problemy pered teoriei struktury goryachih yupiterov. Obsudit' v ZhZh-soobshestve ru_astroph.

Fukui, et al. Comments: 13 pages 31 Oktyabrya 2006 goda yaponskii lyubitel' astronomii A. Tago obnaruzhil sil'noe (4.5 zvezdnyh velichiny) uvelichenie bleska odnoi iz zvezd v sozvezdii Kassiopei. Okazalos', chto vozrastanie bleska bylo vyzvano mikrolinzirovaniem. V dannoi stat'e avtory detal'no razbirayut dannoe sobytie. Obychno sobytiya mikrolinzirovaniya ishut v bogatyh zvezdnyh polyah. Zdes' zhe vse proishodit ne v napravlenii na blizkuyu galaktiku ili baldzh nashei Galaktiki, a v obychnom (bednom) zvezdnom pole. Eto pervoe takoe sobytie. Krome togo, okazalos', chto istochnikom posluzhila blizkaya i yarkaya zvezda (rasstoyanie okolo 1 kpk, blesk okolo 11.4 velichiny), chto ne udivitel'no, koli uzh my razbiraem takoi neobychnyi sluchai.

A. McLaughlin et al. Comments: 10 pages, 5 figures, accepted by ApJ Vse pomnyat, chto paru let nazad byl obnaruzhen novyi klass neitronnyh zvezd - vrashayushiesya radiotranzienty (RRATs). Sluchaino, odin iz nih udalos' uvidet' v rentgene - on prosto popal v pole zreniya Chandry. Teper' na osnove glubokih nablyudenii na XMM-Newton avtory rasskazyvayut o dvuh novyh otkrytiyah. Vo-pervyh, udalos' uvidet' period pul'sacii i v rentgene. On okazalsya ravnym 4.26 sekundy, chto soglasuetsya s dannymi radionablyudenii. Vo-vtoryh, v spektre obnaruzhena spektral'naya detal', kotoruyu mozhno interpretirovat' kak protonnuyu ciklotronnuyu liniyu. Togda rech' idet o magnitnom pole okolo 1014 Gauss.
