Obzory preprintov astro-ph Vypusk N96 astro-ph za 01 - 16 yanvarya 2005 goda: izbrannye stat'i Goryachie temy nedeli Zvezdy Hochetsya eshe raz vydelit' dva otkrytiya, svyazannyh s zvezdami. Eto obnaruzhenie magnitnogo polya u zvezd planetarnyh tumannostei i otkrytie zvezdy s ochen' vysokoi prostranstvennoi skorost'yu. Zachastuyu sovremennaya astronomiya associiruetsya lish' s samymi goryachimi temami v nei: kosmologiya, chernye dyry, ekzoplanety, polety k telam Solnechnoi sistemy i t.p. Odnako i izuchenie zvezd po-prezhnemu daet novye vazhnye i interesnye rezul'taty. V etot vypusk my vklyuchili vsego dve (samye interesnye, na nash vzglyad) raboty po zvezdam. Odnako ih za pervuyu polovinu yanvarya poyavilos' nemalo. Vse zhelayushie priglashayutsya na prostory Arhiva. Referaty otdel'nyh statei miniobzor astro-ph/0501002 Fizika sverhnovyh (Physics of Supernovae) Authors: D. K. Nadyozhin, V. S. Imshennik Comments: 15 pages, 7 figures, 1 table, 72 references; Invited Lecture at the ECRS-19 (Florence, Italy, Aug.-Sep. 2004) Posle kratkogo no soderzhatel'nogo obzora osnovnyh svoistv sverhnovyh avtory perehodyat k svoei modeli, i v nekotoryh detalyah obsuzhdayut neitrinnyi signal ot SN1987A i svyazannye s etim problemy i puti ih resheniya. astro-ph/0501040 Otkrytie magnitnyh polei central'nyh zvezd planetarnyh tumannostei (Discovery of magnetic fields in central stars of planetary nebulae) Authors: Stefan Jordan et al. Comments: 8 pages, 4 figures, Accepted for Publication by Astronomy & Astrophysics See also press release by A&A on their homepage www.edpsiences.org S pomosh'yu teleskopov VLT vpervye udalos' zaregistrirovat' magnitnye polya u central'nyh zvezd planetarnyh tumannostei! Sdelano eto pri pomoshi polyarimetricheskih nablyudenii. Vsego dannye polucheny dlya chetyreh ob'ektov. Polya sostavlyayut poryadka tysyach Gauss. Vazhno, chto vsego-to i bylo issledovano chetyre istochnika. T.e. dlya vseh ob'ektov v vyborke byl poluchen nenulevoi rezul'tat (hotya dlya dvuh zvezd dostovernost' izmerennyh polei ne velika). Vyskazyvaetsya gipoteza, chto polya budut tak ili inache zatuhat' pri perehode zvezdy so stadii yadra planetarnoi tumannosti k stadii belogo karlika. Osnovaniem dlya etoi gipotezy sluzhit maloe kolichestvo sil'no zamagnichennyh belyh karlikov (a pri sohranenii magnitnogo potoka pole karlika budet sushestvenno vyshe polya yadra planetarnoi tumannosti). Avtory obsuzhdayut, kak nablyudaemye polya mogut vliyat' na morfologiyu tumannosti. Oni polagayut, chto imenno magnitnoe pole otvetstvenno za bipolyarnuyu strukturu mnogih planetarnyh tumannostei. miniobzor astro-ph/0501046 Sostoyanie IceTop v 2004 g. (IceTop Status in 2004) Authors: Todor Stanev Comments: 4 pages, 3 figures, Presentation at the Neutrino Oscillation Workshop - NOW2004 Dekabr'-yanvar' - pora podvedeniya itogov. V etoi nebol'shoi zametke rasskazyvaetsya o tom, chto proishodilo s ustanovkoi IceTop v proshlom godu. Napomnim, chto IceTop - eto "verhushka aisberga", nazyvaemogo IceCube, t.e. eto nazemnaya chast' gigantskogo neitrinnogo teleskopa. Oba detektora tol'ko stroyatsya, poetomu "mnogoe sdelano, no mnogoe eshe predstoit". V dekabre nachalas' ustanovka nekotorogo oborudovaniya. Sm. takzhe obzor The Pierre Auger Observatory -Status and Prospects, v kotorom opisyvaetsya sostoyanie del v proekte Auger. miniobzor astro-ph/0501049 Kak obrazuyutsya korichnevye karliki? (How do brown dwarves form?) Authors: Anthony P. Whitworth, Simon P. Goodwin Comments: To appear in the proceedings of "Low Mass Stars and Brown Dwarfs: IMF, Accretion and Activity" (Volterra, 2004). 6 pages, 1 figure Rassmotreny chetyre mehanizma obrazovaniya korichnevyh (buryh) karlikov: vybros zvezdnogo zarodysha iz formiruyushegosya yadra za schet dinamicheskogo vzaimodeistviya; fragmentaciya szhatogo sloya iz-za neprozrachnosti; gravitacionnye neustoichivosti v diskah, vyzvannye vzaimodeistviem s drugimi diskami; fotoeroziya (t.e. razrushenie izlucheniem) protozvezdnyh yader. Avtory polagayut, chto vazhno nabirat' statistiku po dvoistvennosti korichnevyh karlikov, a takzhe, chto nado detal'nee issledovat' diski vokrug etih ob'ektov. Takzhe sm. stat'yu The Decay of Accreting Triple Systems as Brown Dwarf Formation Scenario, gde opisan eshe odin mehanizm. miniobzor astro-ph/0501057 Razborki s temnoi energiei (Dealing with Dark Energy) Authors: Eric V. Linder Comments: 14 pages, 2 figures; to be published in 5th International Heidelberg Conference, DARK2004 Konechno, perevod zagolovka stat'i ne vpolne adekvaten, tem ne menee, na nash vzglyad, on "catchy" i peredaet smysl proishodyashego: nuzhno imenno chto razobrat'sya s etim fenomenom. Ne budem pereskazyvat' soderzhanie obzora. V nem opisany osnovnye dostizheniya, problemy i plany, svyazannye s temnoi energiei. astro-ph/0501089 Mozhet li astronomiya upravit'sya so svoimi dannymi? (Can Astronomy Manage Its Data?) Authors: Ray P Norris Comments: 5 pages, IAU Bulletin, 2005, #96, 16 Korotko obsuzhdayutsya osnovnye problemy, svyazannye s obiliem dannyh nablyudenii v astronomii. Hochetsya vse eto imet' v uporyadochennom legko dostupnom svobodnom dostupe. No sdelat' takuyu sistemu dovol'no neprosto. Budem nadeyat'sya, chto sozdanie Virtual'noi observatorii po bol'shei chasti reshit vse eti problemy. astro-ph/0501119 Ekspansivnye razvitye civilizacii vo vselennoi (Expanding advanced civilizations in the universe) Authors: Claudius Gros Comments: JBIS, in press Korotkaya zametka, posvyashennaya ondmu iz vozmozhnyh reshenii paradoksa Fermi. Napomnim, chto sut' paradoksa sostoit v vyskazyvanii: "esli by vnezemnye civilizacii sushestvovaoli, to ih korabli uzhe byli by v Solnechnoi sisteme" (sm., naprimer, diskussiyu i ssylki na saite "Russkii Pereplet"). Avtor predstavlyaet optimisticheskuyu chast' issledovatelei, schitayushih, chto vse-taki mozhno neprotivorechivo uvyazat' otsutstvie skol'-nibud' dostovernyh dannyh o "zvezdoletah na Zemle" s sushestvovaniem mnozhestva civilizacii v nashei Galaktike. Pravda, na nash vzglyad, rassuzhdeniya avtora ne bleshut noviznoi. Po suti, on rassmatrivaet situaciyu, v kotoroi ne proishodit bystroi ekspansii razvitoi tehnicheskoi civilizacii. Tochnee, periody burnogo rosta peremezhayutsya dlinnymi epohami zastoya. istoricheskii obzor astro-ph/0501170 Vest-saidskaya istoriya (West-Side Story [On the History of Density-Wave Spiral Theories in the 1960s]) Authors: Leonid Marochnik Comments: 16 pages My pisali o dvuh stat'yah Igorya Pashi, posvyashennyh istorii issledovaniya struktur galaktik (v Arhive oni vyhodili v 2004 godu). Dannyi obzor predstavlyaet soboi nekotoroe "algebraicheskoe dopolnenie". Po mneniyu Leonida Marochnika v obzorah Pashi nedostatochno opisan vklad sovetskih uchenyh. Sootvetstvenno, Marochnik daet etu dopolnitel'nuyu informaciyu i delitsya svoimi sobstvennymi vospominaniyami (a emu est' chto vspomnit'! ego [v soavtorstve s Suchkovym] knigu "Galaktika" znayut, navernoe, vse astronomy, chitayushie po-russki, i ne tol'ko po-ruski, t.k. ona byla perevedena). Nekotoraya ironiya, na nash vzglyad, sostoit v tom, chto seichas Igor' Pasha prodolzhaet rabotat' v Rossii, a Leonid Marochnik zhivet i rabotaet v SShA. astro-ph/0501177 Otkrytie nesvyazannoi giperskorostnoi zvezdy v galo Mlechnogo Puti (Discovery of an Unbound Hyper-Velocity Star in the Milky Way Halo) Authors: Warren R. Brown et al. Comments: 4 pages, submitted to ApJ Letters Otkryta zvezda, dvizhushayasya s ochen' vysokoi skorost'yu - okolo 800 km/s. Avtory polagayut, chto ona mogla byt' vybroshena iz central'noi oblasti Galaktiki za schet dinamicheskogo vzaimodeistviya. obzor astro-ph/0501189 Forma kosmosa po dannym WMAP (The Shape of Space after WMAP data) Authors: Jean-Pierre Luminet Comments: 19 pages, 9 postscript figures. Invited talk at the XXV Brazilian National Meeting on Elementary Particles and Fields, 23-27 August 2004. To be published in Brazilian Journal of Physics Navernoe, mnogim pamyatna diskussiya, razgorevshayasya posle publikacii raboty Luminet s soavtorami v Nature. V etom obzore on daet svodku rezul'tatov (i podhodov) svyazannyh s izucheniem topologii Vselennoi po dannym o reliktovom izluchenii. obzor astro-ph/0501195 Vazhneishie problemy kosmomikrofiziki (Outstanding Problems in Particle Astrophysics) Authors: Thomas K. Gaisser Comments: 32 pages, 9 figures. This paper combines two lectures presented at the 14th International School of Cosmic Ray Astrophysics: "Neutrinos and Explosive Events in the Universe", July, 2004 My pozvolili sebe ispol'zovat' dlya perevoda Particle Astrophysics bolee privychnyi dlya russkogo uha termin "kosmomikrofizika". Dannaya stat'ya predstavlyaet soboi summu dvuh lekcii, prochitannyh v iyule etogo goda v Eriche (smeyu vas zaverit', chto lekcii byli interesnymi - S.P.). Shkola byla posvyashena v osnovnom kosmicheskim lucham, sootvetstvenno i v etih lekciya mnogo govoritsya ob etoi tematike. obzor astro-ph/0501196 Dinamicheskaya evolyuciya galaktik s peremychkami (Dynamical Evolution of Barred Galaxies) Authors: E. Athanassoula Comments: 24 pages, 11 figures, invited review, 2004 DDA meeting in Cannes, april 19-23, Celestial Mechanics & Dynamical Astronomy (in press) Novye dannye nablyudenii (v pervuyu ochered' s Kosmicheskogo teleskopa) dayut mnogo novoi informacii po morfologii galaktik. V etoi stat'e rech' idet o galaktikah s peremychkami (barami). V osnovnom avtor koncentriruetsya na teoreticheskoi storone problemy, no ne oboideny vnimaniem i real'nye dannye. astro-ph/0501199 SGARFACE: novyi detektor dlya mikrosekundnyh gamma-vspleskov (SGARFACE: A Novel Detector For Microsecond Gamma Ray Bursts) Authors: S. LeBohec et al. Comments: 29 pages, 14 figures, accepted for publication in Astroparticle Physics Rech' idet o nazemnyh nablyudeniyah na observatorii Whipple na 10-metrovom gamma-teleskope. Novaya apparatura pozvolit detektirovat' zhestkie gamma-kvanty (>100 MeV) vo vspyshkah s dlitel'nost'yu do 35 mikrosekund! astro-ph/0501216 Analiz istoricheskih dannyh po meteoram i meternym dozhdyam (Analysis of historical meteor and meteor shower records: Korea, China, and Japan) Authors: Hong-Jin Yang et al. Comments: 29 pages, 7 figures. To appear in Icarus Avtory ispol'zovali tri sbornika koreiskih letopisei, pokryvayushih periody 57 g. do n.e.- 935 g. n.e., 918 - 1392 i 1392-1910. Obnaruzheny dannye o 3861 meteore i 31 dozhdyah. Dannye sravnivayutsya s zapisyami v kitaiskih i yaponskih letopisyah. Odnim iz interesnyh rezul'tatov yavlyaetsya obnaruzhenie umen'sheniya aktivnosti Perseid na ochen' bol'shom promezhutke vremeni. obzor astro-ph/0501226 Pul'sary v sharovyh skopleniyah (Pulsars in Globular Clusters) Authors: Fernando Camilo, Frederic A.

A. Rasio & I. H. Stairs (San Francisco: ASP), p. 147 Bolee 100 radiopul'sarov obnaruzheno v 24 sharovyh skopleniyah (napominim, chto samih skoplenii gorazdo bol'she, prosto ne vo vseh poka (?) obnaruzhili radiopul'sary). Fakticheski vse pul'sary millisekundnye, t.e. "raskruchennye" akkreciei. Eto starye neitronnye zvezdy, period vrasheniya kotoryh byl umen'shen za schet uglovogo momenta veshestva, natyanutogo s kompan'ona v tesnoi dvoinoi sisteme. Pochti polovina izvestnyh radiopul'sarov v sharovyh skopleniyah nahoditsya v Terzan 5 i 47 Tukana. O skoplenii Terzan 5 est' otdel'naya svezhaya (dovol'no populyarnaya) stat'ya. miniobzor astro-ph/0501264 Akkreciruyushie millisekundnye pul'sary (Accretion-driven millisecond X-ray pulsars) Authors: Rudy Wijnands Comments:To appear in Nova Science Publishers (NY) volume "Pulsars New Research" Vyshe my napisali, chto millisekundnye radiopul'sary byli raskrucheny v tesnyh dvoinyh sistemah. Odnako dolgoe vremya astronomy ne mogli zaregistrirovat' akkreciruyushie millisekundnye pul'sary. Takie ob'ekty dolzhny byli by nablyudat'sya kak rentgenovskie istochniki. Lish' neskol'ko let nazad oni byli obnaruzheny. Pervoi otkrytoi sistemoi etogo tipa stal istochnik SAX J1808.4-3658 (SAX v nazvanii ukazyvaet, chto otkrytie bylo sdelano na sputnike BeppoSAX). Imenno etomu ob'ektu posvyashena bOl'shaya chast' predstavlyaemogo obzora. Otmetim zdes' i druguyu svezhuyu stat'yu.
