    astro-ph/0510809 Tendencii v kosmicheskoi astronomii i Obraz Kosmosa 2015-2025 (Trends in Space astronomy and Cosmic vision 2015-2025)
    Authors: Catherine Turon et al.
    Comments: 6 pages.

    V stat'e predstavleny osnovnye napravleniya razvitiya evropeiskih kosmicheskih proektov, svyazannyh s astronomiei.

    Nedavno ESA byl ob'yavlen konkurs na proekty, osushestvlenie kotoryh otnositsya k 2015-2025 gg., a takzhe na chut' bolee dalekuyu perspektivu. Bylo podano bolee 150 zayavok, iz nih 47 imeyut pryamoe otnoshenie k astronomii. Bezuslovno podderzhka proektov osnovana na nekotorom anlize naibolee perspektivnyh napravlenii. Ih bylo vydeleno tri.
    1. Drugie miry i zhizn' vo Vselennoi
    a) Ekzoplanety
    b) Zhizn'
    c) Obrazovanie zvezd i planet
    2. Rannyaya Vselennaya
    a) Temnaya energiya
    b) Inflyaciya
    c) Obrazovanie struktur
    3. Evolyuciya yarostnoi (violent) Vselennoi
    a) Povedenie veshestva v ekstremal'nyh usloviyah
    b) Chernye dyry
    c) Sverhnovye

    Zatem etot spisok byl sveden k chetyrem osnovnym voprosam, na kotorye dolzhna otvetit' astronomiya v blizhaishie dva desyatiletiya.
    1. Kakovy usloviya dlya obrazovaniya planet i poyavleniya zhizni?
    2. Kak poyavilas' Solnechnaya sistema?
    3. Kakovy fundamental'nye zakony Vselennoi?
    4. Kak poyavilas' nablyudaemaya Vselennaya i iz chego ona sdelana?

    Pozhalui, krome pervyh dvuh, voprosy slishkom obshie. Tem ne menee, odobrennye proekty dolzhny pomoch' naiti na nih otvety, ili hotya by prodvinut'sya v ih ponimanii.

    V blizhaishee vremya prodvizhenie v ponimanii ustroistva Vselennoi svyazyvaetsya s takimi proektami:
    1. Corot (ESA) i Kepler (USA). Eti missii prednaznacheny dlya poiska planet tipa Zemli.
    2. Herschel (ESA) i JWST (USA-ESA-others). Eti moshnye infrakrasnye observatorii pozvolyat luchshe razobrat'sya v processah obrazovaniya zvezd i planetnyh sistem.
    3. GAIA (ESA) i SIM (USA). Eti astrometricheskie missii, krome vsego prochego, pomogut rezko uvelichit' chislo izvestnyh planet-gigantov.

    V neskol'ko bolee otdalennom budushem evropeiskie astronomy poluchat kosmicheskii interferometr, rabotayushii v IK diapazone. On budet nuzhen dlya detal'nogo issledovaniya planet tipa Zemli. V chastnosti, mozhno budet napryamuyu izuchat' ih atmosfery. Krome togo, budet postroen bol'shoi kosmicheskii infrakrasnyi teleskop.

    Posle missii Planck, prdnaznachennoi dlya izucheniya mikrovolnovogo fona (t.e. reliktovogo izlucheniya) budet postroen eshe bolee moshnyi pribor, nuzhnyi dlya detal'nogo issledovaniya polyarizacii relikta. Eto pozvolit ponyat', kakoi byla Vselennaya srazu posle stadii inflyacii.

    Nakonec budet postroena novaya rentgenovskaya observatoriya, kotoraya pridet na smenu XMM-Newton. A chut' pozzhe i gamma-observatoriya, kotoraya prizvana zamenit' sputnik INTEGRAL.

    Kak vidno, evropeiskuyu astronomiyu zhdet blestyashee budushee.


    astro-ph/0511057 Rasshirennyi glubokii obzor Chandra: opticheskie svoistva rentgenovskih istochnikov (The Extended Chandra Deep Field-South Survey: Optical Properties of X-ray Detected Sources)
    Authors: Shanil Virani et al.
    Comments: 2 pages, 4 figures; to be published in the proceedings of "The X-ray Universe 2005" conference, San Lorenzo de El Escorial, Madrid, Spain.

    Kratko (eto ne polnaya stat'ya, a korotkaya zametka dlya materialov konferencii) predstavleny rezul'taty po opticheskomu otozhdestvleniyu istochnikov, obnaruzhennyh v pole glubokogo obzora Chandry na yuzhnom nebe. Na ploshadke v 0.3 kvadratnyh gradusa obnaruzheny sotni istochnikov. Osobenno interesnym yavlyaetsya obnaruzhenie semi, dlya kotoryh ne udalos' obnaruzhit' opticheskih "dvoinikov" (t.e. v rentgene istochniki vidny, a v optike - net). Otmechu veroyatnost' togo, chto sredi etoi semerki mogut byt' odinochnye akkreciruyushie neitronnye zvezdy ili chernye dyry.


    astro-ph/0511068 Gravitacionnoe izluchenie ot novorozhdennyh magnitarov (Gravitational Radiation from Newborn Magnetars)
    Authors: Luigi Stella et al.
    Comments: 5 pages, Accepted for publication on ApJ Letters

    Ya uzhe pisal nedavno o rabote, svyazannoi s gravitacionnym izlucheniem magnitarov. Vot eshe odna. Zdes' rech' idet ne o fone, a ob izluchenii ot skopleniya v Deve. V samom dele, tam temp rozhdeniya magnitarov dolzhen byt' dostatochno vysok, a avtory pokazyvayut, chto pri nachal'nom pole poryadka 1016.5 Gs gravitacionno-volnovi signal budet dostatochno silen, chtoby istochnik udalos' uvidet' modernizirovannoi versiei LIGO. Nalichie signala svyazano s tem, chto moshnoe magnitnoe pole deformiruet neitronnuyu zvezdu, i ona stanovitsya istochnikom gravitacionnyh voln (zvezda budet nesimmetrichna otnositel'no osi vrasheniya iz-za magnitnoi deformacii, sootvestvenno vozniknet precessiya). Ocenki pokazyvayut, chto temp rozhdeniya magnitarov v skoplenii v Deve dolzhen byt' poryadka shtuki v god. T.o., esli predpolozhenie o bystrom nachal'nom vrashenii magnitarov i o tom, chto pri rozhdenii ih pole dostigaet 1016.5 Gs, verno, to modernizirovannaya ustanovka LIGO budet videt' odin vsplesk v god, chto nemalo. Otmechu, odnako, chto izbytka gamma vspleskov magnitarov ot etogo skopleni galaktik my ne vidim.

    Authors: D. L. Kaplan, M. H. van Kerkwijk
    Comments: 5 pages, 2 figures. ApJL in press

    V rabote privedeny dannye po tochnomu opredeleniyu tempa zamedleniya i drugih parametrov dlya odnoi iz zvezd, sostavlyayushih Velikolepnuyu semerku. Novye dannye zadayut i novye voprosy. Naprimer, vozrast istochnika, opredelennyi po tempu zamedleniya sushestvenno vyshe, chem vozrast, opredelennyi po temperature. Znachit, ili neitronnaya zvezda rodilas' s periodom poryadka 7-8 sekund, ili zhe ran'she ona gorazdo bystree zamedlyalas'.

    Authors: Ignacio Negueruela et al.
    Comments: To appear in Proceedings of "The X-ray Universe 2005", held in San Lorenzo de El Escorial (Madrid, Spain), 26-30 September 2005, ESA-SP 604. 6 pages, 6 figures

    Regulyarnye nablyudeniya galakticheskoi ploskosti na sputnike INTEGRAL pozvolili obnaruzhit' bol'shoe kolichestvo rentgenovskih tranzientov (t.e. vspyhivayushih istochnikov), svoistva kotoryh otlichayutsya ot ranee izvestnyh. Vse eto moshnye vspyshki, razvivayushiesya za neskol'ko minut i dlyashiesya chasy. Nektorye iz istochnikov seichas nadezhno otozhdestvleny s massivnymi zvezdami (spektral'nye klasy O-V), t.e. eto massivnye dvoinye sistemy (ochevidno, chto vtoroi komponent dolzhen byt' neitronnoi zvezdoi).

    T.k. chislo izvestnyh istochnikov novogo tipa uzhe veliko pri tom, chto obnaruzhit' ih neprosto (iz-za togo, chto znachitel'noe vremya oni provodyat v spokoinom sostoyanii), to avtory zaklyuchayut, chto my mozhem imet' delo s edva li ne samym mnogochislennym klassom massivnyh dvoinyh sistem.

    Authors: Steven Weinberg
    Comments: 13 pages

    Pis'mennaya versiya doklada, prochitannogo nedavno Stivenom Vainbergom v Triniti kolledzhe (kolledzhe Svyatoi Troicy, esli komu-to tak bol'she nravitsya).

    Chitat' stoit. Ni formul, ni kartinok tam net, zato est' podrobnye i ponyatnye ob'yasneniya.

    V osnovnom rech' idet ob antropnyh argumentah. V pervuyu ochered' v svyazi s rezul'tatami teorii strun (gde poluchaetsya bezumnoe kolichestvo vozmozhnyh vakuumov, vybor sredi kotoryh [poka?] ne predstavlyaetsya vozmozhnym), no ne tol'ko. Takzhe upominaetsya teoriya haoticheskoi inflyacii i argumenty Andreya Linde, a takzhe nekotorye interpretacii kvantovoi mehaniki.

    Sovetuyu dochitat' do konca, i ulybnut'sya poslednei stavke Stivena Vainberga.


    astro-ph/0511142 Kollaps gipermassivnoi zamagnichennoi neitronnoi zvezdy: central'naya mashina dlya korotkih gamma-vspleskov (Magnetized hypermassive neutron star collapse: a central engine for short gamma-ray bursts)
    Authors: Masaru Shibata et al.
    Comments: 4 pages, 2 figures, submitted to Phys. Rev. Letter

    V proshlom vypuske ya uzhe pisal o pervoi rabote etoi gruppy avtorov. Imi rassmatrivaetsya kollaps bystrovrashayusheisya massivnoi zamagnichennoi neitronno zvezdy, obrazovavsheisya v reuzl'tate sliyaniya dvuh neitronnyh zvezd. V predydushei stat'e avtorami lish' kratko byla otmechena vozmozhnost' generacii korotkogo gamma-vspleska pri takom kollapse. V etoi zhe stat'e modelirovanie vspelska yavlyaetsya osnovnoi temoi.

    Comments: 23 pages, 48 figures, Proc. of the workshop "Gravity, Astrophysics and Strings at the Black Sea" June 13-20, 2005, Bulgaria

    Ocherednaya stat'ya izvestnoi rossiiskoi gruppy, razrabatyvayushei model' magnitorotacionnogo vzryva sverhnovoi. Poskol'ku model' postoyanno razvivaetsya, sovershenstvuetsya, to novye stat'i soderzhat novye detali. Rekomenduetsya k prochteniyu vsem, kogo interesuet, kak vzryvayutsya massivnye zvezdy (rech' idet tol'ko o takih sverhnovyh, t.e. ne o tipe Ia).


    obzor astro-ph/0511176 Dvoinye kak astrofizicheskie laboratorii: obzor (Binaries as astrophysical laboratories: an overview)
    Authors: Carla Maceroni
    Comments: 13pages, 4 figures. Invited talk at ENEAS-PHD School on Variable Stars. Pecs (Hungary), September 2005

    Kak izvestno, mnogie zvezdnye parametry (naprimer, massy) tochno mozhno izmerit' tol'ko dlya komponent dvoinyh. Imenno poetomu dvoinye sistemy mozhno nazvat' laboratoriyami astrofiziki, gde zvezdy odnovremenno yavlyayutsya i ob'ektom issledovaniya i testerom. V obzore summirovany osnovnye "eksperimenty", kotorye mozhno stavit' v takih laboratoriyah.

    Daetsya obzor poslednih rezul'tatov po nablyudeniyam galakticheskogo centra na vysokih energiyah (rentgen, gamma). Razumeetsya, vo mnogom eto rezul'taty sputnika INTEGRAL.

    Ob odnom rezul'tate, poluchennom na INTEGRALE, mozhno takzhe podrobno prochest' zdes'.


    astro-ph/0511245 Vozmozhnoe ukazanie na vybros sverhmassivnoi chernoi dyry pri sliyanii galaktik (Possible evidence for the ejection of a supermassive black hole from an ongoing merger of galaxies)
    Authors: Martin G. Haehnelt et al.
    Comments: 4 pages, LaTeX, no figures; MNRAS in press

    Obnaruzhenie kvazarov bez hozyaiskih galatik (rech' idet o yarkom kvazare HE0450--2958 ) ne moglo ne privesti k idee o tom, chto sobstvenno kvazar - t.e. sverhmassivnaya chernaya dyra, podpityvaemaya akkreciei - mozhet vybrasyvat'sya iz centra galaktiki iz-za dinamicheskogo vzaimodeistviya. Poyavilos' srazu dve stat'i na etu temu (vtoraya - astro-ph/0511242).

    Otmetim, chto krome obychnogo ("n'yutonovskogo") vybrasyvaniya za schet vzaimodeistviya treh tel (t.e. nuzhno, chtoby vo zaimodeistvii uchastvovali tri sverhmassivnye chernye dyry, chto vpolne mozhet, i dazhe dolzhno, proishodit' pri posledovatel'nom sliyanii galaktik) mozhet takzhe rabotat' mehanizm gravitacionnoi rakety, kogda chernaya dyra, obrazovavshayasya v rezul'tate sliyaniya dvuh dyr, budet priobretat' impul's za schet nesimmetrichnogo gravitacionnogo izlucheniya.

    Ne vse soglasny s ideei o vybrose. Tak David Meritt i ego soavtory v svoei stat'e (astro-ph/0511315) osparivayut vsyu cepochku rassuzhdenii. Oni polagayut, chto na samom dele massa chernoi dyry na poryadok men'she. Sootvetstvenno, eto ne kvazar, a seifertovskaya galaktika. Togda verhnii predel na svetimost' galaktiki nichemu ne protivorechit, t.e. nel'zya voskliknut': "a kvazar-to golyi!" Prosto galaktika slishkom slaba, chtoby ee razglyadet'.

    Kogda-to ya uzhe rasskazyval o zamechatel'nom proekte Living Reviews on Relativity. Eto setevoi obzornyi zhurnal, publikuyushii obzory po sootvetstvuyushei tematike. Vazhno, chto periodicheski avtory vykladyvayut obnovlennye versii svoih obzorov. Nastoyashaya stat'ya kak raz yavlyaetsya ocherednym primerom. Dunkan Lorimer vylozhil novuyu versiyu svoego obzora po dvoinym i millisekundnym pul'saram. Pozhalui, eto samyi polnyi obzor po teme.

    Authors: F.R. Klinkhamer, C. Rupp
    Comments: 9 pages with elsart; solicited talk at A Life With Stars (Conference in Honor of Ed van den Heuvel), Amsterdam, August, 2005

    Kak izvestno, esli prostranstvo-vremya imeet mikrostrukturu, to eto dolzhno skazyvat'sya na rasprostranenii fotonov. Issledovateli neodnokratno obrashalis' k etomu voprosu (mnozhestvo statei ranee uzhe obsuzhdalos' v obzorah). Naibolee prespektivnym vyglyadit poisk effekta pri nablyudenii zhestkih kvantov. V stat'e daetsya kratkii obzor sotvetstvuyushih vozmozhnostei, popytok naiti effekt, verhnih predelov i perspektiv eti predely uluchshit'.


    astro-ph/0511269 Odinochnye massivnye zvezdy pri kriticheskoi skorosti vrasheniya: vozmozhnaya svyaz' s Be i B[e] zvezdami (Single massive stars at the critical rotational velocity: possible links with Be and B[e] stars)
    Authors: Georges Meynet, Andre Maeder
    Comments: 11 pages, 13 figures, Stars with the B[e] phenomenon, M. Kraus and A. Miroshnichenko, ASP Conference Series, in press

    Ve-zvezdy otlichayutsya emissionnymi liniyami, voznikayushimi iz-za ekvatorial'nogo istecheniya. Poslednee svyazano s chrezvychaino bystrym vrasheniem. Standartnyi scenarii govorit, chto takaya situaciya realizuetsya v osnovnom v tesnyh dvoinyh sistemah. T.e. raskrutka svyazana s vozdeistviem kompan'ona. V etoi zhe stat'e avtory (kstati, vedushie eksperty v oblasti zvednoi fiziki i evolyucii) pokazyvayut, chto korotkaya (okolo 10 000 let) stadiya Ve-zvezdy mozhet voznikat' i u odinochnyh zvezd. Zamechu, chto avtory v kachestve nachal'nogo usloviya uzhe berut dostatochno bystroe vrashenie. Krmoe togo, sdelany i drugie sushestvennye predpolozheniya. Tak chto rezul'tat model'no zavisim.


    obzor astro-ph/0511273 Rentgenovskie populyacii v galaktikah (X-ray populations in galaxies)
    Authors: G. Fabbiano
    Comments: This is a review talk,to be published in the proceedings of the IAU Symposium 230, Populations of high energy sources in galaxies, held in Dublin (Ireland), August 15-19, 2005

    Obzor posvyashen poslednim dannym po rentgenovskim istochnikam v gaalktikah. Chto my vidim? Celyi zoopark! Pri etom est' i mnoezhstvo zagadok. Daleko ne vse istochniki identificirovany. Vzyat', k primeru, ul'tramoshnye.

    Otmechu takzhe i dva drugih svezhih obzora Fabbiano: astro-ph/0511273 i Investigating Galaxy Evolution with Chandra. Chemu posvyashen vtoroi yasno iz nazvaniya, a vot pervyi - eto epilog k simpoziumu MAS nomer 230. On soderzhit perechen' naibolee interesnyh rezul'tatov, dolozhennyh na nem.


    astro-ph/0511321 HE 0437-5439 - gravitacionno nesvyazannaya giperskorostnaya V-zvezda glavnoi posledovatel'nosti (HE 0437-5439 -- an unbound hyper-velocity main-sequence B-type star)
    Authors: Heinz Edelmann, Ralf Napiwotzki, Uli Heber, Norbert Christlieb, Dieter Reimers
    Comments: 13 pages, 4 figures. Astrophysical Journal Letters, accepted

    Avtory obnaruzhili interesnuyu zvezdu 16-i velichiny. Eto V-zvezda glavnoi posledovatel'nosti. Ee massa okolo 8 mass solnca. Nahoditsya ona v 61 kpk (!) ot nas. Kak ona tuda zabralas'? U nee ochen' bol'shaya skorost': bolee 700 km/s.

    Est' dva sposoba tak razognat' zvezdu: analog gravitacionnogo manevra (v pole drugoi massivnoi zvezdy, ili, naprimer, v pole sverhmassivnoi chernoi dyry v centre galaktiki) i raspad tesnoi dvoinoi iz-za vzryva sverhnovoi. T.k. poka ne izvestno tochnoe napravlenie dvizheniya zvezdy, to ne yasno vyletela li ona iz central'noi oblasti nashei Galaktiki, ili zhe iz Bol'shogo Magellanovogo Oblaka. Esli iz Oblaka, to togda yasno, chto sverhmassivnaya chernaya dyra tut ni pri chem.

    V drugoi stat'e (astro-ph/0511323) Hirsh i ego kollegi rasskazyvayut ob analogichnom otkrytii. Oni takzhe obnaruzhili v galo nashei Galaktiki zvezdu so skorost'yu (kak i vyshe rech' idet o skorosti otnositel'no Solnca) okolo 700 km/s. Dlya etoi zvezdy takzhe nuzhno prinyat' neobychnyi evolyucionnyi put' (sliyanie dvuh belyh karlikov, a zatem vybros za schet sverhmassivnoi chernoi dyry), t.k. esli by eto byla prosto obychnaya massivnaya zvezda, to posle vybrosa iz centra Galaktiki ona ne uspela by zabrat'sya tak daleko (19 kpk ot centra) za vremya svoei zhizni.

    Authors: Martin C. Weisskopf, John P. Hughes
    Comments: 82 pages, 28 figures, for the book Astrophysics Update 2

    Veroyatno, mnogie pomnyat, chto "pervyi svet" Chandry - eto nablyudeniya ostatka sverhnovoi Cas A, prichem uzhe eti nablyudeniya priveli k otkrytiyu zagadochnogo tochechnogo ob'ekta v centre tumannosti, pro kotoryi do sih por ne yasno: neitronnaya zvezda eto ili chernaya dyra. V bol'shom materiale avtory summiruyut vsyu informaciyu po ostatkam sverhnovyh, poluchennuyu za 6 let na Chandre. Mnogo kartinok.
