Obzory preprintov astro-ph Vypusk N125 astro-ph za 18 - 20 yanvarya 2006 goda: izbrannye stat'i Referaty otdel'nyh statei miniobzor astro-ph/0601346 Kratnost', aktivnost' i bystroe vrashenie zvezd rannih spektral'nyh klassov (Multiplicity, activity and fast rotation in early-type stars) Authors: Ignacio Negueruela Comments: Review to appear in "Active OB Stars: Laboratories for Stellar & Circumstellar Physics", eds. S. Stefl, S. P. Owocki & A. Okazaki. ASP Conf. Ser. 2006, in press (uses asp style). Obzor posvyashen fenomenu Ve-zvezd. Eto zvezdy klasa V s emissionnymi liniyami v spektre. Dolya takih zvezd sredi vseh massivnyh dostatochno velika, krome togo horosho izvestny rentgenovskie sistemy s Ve-zvezdami, sostavlyayushie bOl'shuyu chast' vseh rentgenovskih dvoinyh. V osnovnom rech' idet o proishozhdenii Ve-zvezd. Rezyume: neponyatno, kak oni obrazuyutsya. Tochnee tak, yasno, chto est' neskol'ko kanalov obrazovaniya Ve-zvezd, prichem nekotorye kanaly neizvestny. Shiroko rasprostraneno mnenie, chto Ve-zvezdy mogut obrazovyvat'sya vo vzaimodeistvuyushih dvoinyh za schet perenosa massy s bolee massivnogo kompan'ona. I etot mehanizm rabotaet! No, kak yasno iz obzora, ne dlya vseh zvezd. Prichem i dolya teh, dlya kotoryh rabotaet, ne yasna. Tak chto, kak obychno, mnogoe sdelano, no mnogoe eshe predstoit! obzor astro-ph/0601356 Vvedenie: paleogeliosfera protiv paleoMMZS (Introduction: Paleoheliosphere versus PaleoLISM) Authors: Priscilla C. Frisch Comments: The article will appear in the book "Solar Journey: The Significance of Our Galactic Environment for the Heliosphere and Earth", Springer, in press (2006), editor P. C. Frisch Glava iz knigi (sm. takzhe astro-ph/0601359). MMZS - Mestnaya mezhzvezdnaya sreda. Obsuzhdaetsya, kak variacii MMZS mogut vliyat' na zemnoi klimat. Vsem sovetuyu!!!! astro-ph/0601357 Izmerenie mer vrasheniya pul'sarov i krupnomasshtabnaya struktura galakticheskogo magnitnogo polya (Pulsar rotation measures and the large-scale structure of Galactic magnetic field) Authors: J.L. Han et al. Comments: ApJ accepted. 16 pages, 14 figures, 2 tables, 223 pulsar RMs Po dannym o mere vrasheniya pul'sarov (eto ne nechto, svyazannoe s vrasheniem samih neitronnyh zvezd, eta velichina pokazyvaet kak izmenilas' orientaciya ploskosti polyarizacii izluchennoi pul'sarov elektromagnitnoi volny po mere ee rasprostraneniya ot istochnika k priemniku) mozhno izuchat' strukturu magnitnogo polya Galaktiki. Avtory na osnove izmereniya mer vrasheniya dlya 223 radiopul'srov poluchayut kartinu global'nogo magnitnogo polya nashei zvezdnoi sistemy. Na risunke pokazano napravlenie magnitnogo polya v Galaktike po dannym o mere vrasheniya pul'sarov. astro-ph/0601375 Kratnost' zvezd i nachal'naya funkciya mass: bol'shinstvo zvezd rozhdaetsya odinochnymi (Stellar Multiplicity and the IMF: Most Stars Are Single Born) Authors: Charles J. Lada Comments: Submitted to Astrophysical Journal Letters, 5 pages, 2 figures Na osnove poslednih dannyh po zvezdam pozdnih spektral'nyh klassov delaetsya vyvod o tom, chto bol'shinstvo zvezd v Galaktike vse-taki odinochnye. Na samom dele, rezul'tat vse-taki kolichestvennyi, a ne kachestvennyi (na moi vzglyad). Esli ranee schitali, chto 2/3 zvezd dvoinye, to Lada govorit, chto 2/3 odinochnye. Te, kto v raschetah schitali, chto 1/2 zvezd dvoinye, mogut nichego v raschetah ne menyat'! Krome togo, odinochnost' yavlyaetsya v osnovnom svoistvom malomassivnyh zvezd (spektral'nye klassy K i pozdnee). Poskol'ku imenno eti zvezdy naibolee mnogochislenny, to otsyuda i sleduet vyvod o tom, chto bOl'shaya chast' zvezd v Galaktike odinochnye. Kstati skazat', tot fakt, chto dvoistvennost' menyaetsya dlya zvezd raznyh mass, dolzhen sushestvenno vliyat' na raschety metodom populyacionnogo sinteza dlya tesnyh dvoinyh sistem. Naskol'ko ya znayu, vse schitayut, chto dolya dvoinyh ne zavisit ot massy kompan'onov. Hotya obychno v raschetah interesuyutsya massivnymi sistemami (t.e. hotya by odin komponent dostatochno massiven, chtoby uspet' proevolyucionirovat' do kompaktnogo ostatka), a dlya takih sistem vse, vrode by, v poryadke (osobenno esli uchest', chto raspredelenie komponent po massam obychno prinimaetsya takim, chto naibolee veroyatny komponenty ravnyh mass). Poluchennyi rezul'tat ochen' vazhen dlya teorii obrazovaniya zvezd (i planet). gr-qc/0601056 Lokal'nye effekty kosmologicheskih izmeneniya fizichekih "konstant" i skalyarnye polya. II Kvazisfericheskoe prostranstvo-vremya (The Local Effects of Cosmological Variations in Physical 'Constants' and Scalar Fields II. Quasi-Spherical Spacetimes) Authors: Douglas J. Shaw, John D. Barrow Comments: 13 pages, 1 figure Ochen' special'naya stat'ya. Tem ne menee, vyvod takov, chto pri nekotoryh razumnyh usloviyah teoreticheski mozhno v laboratornom eksperimente obnaruzhit' izmenenie global'nyh "konstant". astro-ph/0601433 Ogranicheniya na topologiyu vselennoi po polyarizacii reliktovogo izlucheniya (Constraining Cosmic Topology with CMB Polarization) Authors: Alain Riazuelo, Samuel Caillerie, Marc Lachize-Rey, Roland Lehoucq, Jean-Pierre Luminet Comments: 10 pages, submitted to PRD Stat'ya ne obzornaya. Tem ne menee, obsuzhdaetsya dostatochno obshaya vesh' (hotya i na chastnyh primerah). Mnogie pomnyat nedavnie raboty po topologii vselennoi po dannym po reliktovomu izlucheniyu (sm. takzhe stat'yu na Astronete). Sleduyushii shag - eto poluchenie dannyh o topologii po izmereniyu polyarizacii relikta. Uzhe seichas nazemnye (balonnye i t.p.) eksperimenty dayut tut koe-kakuyu informaciyu. A v nedalekom budushem s zapuskom sputnika Plank my poluchim chetkie dannye po polyarizacii relikta. Tak chto teoretiki ne zrya gotovyatsya! astro-ph/0601436 Chuvstvitel'nost' detektorov k vspleskam: proshloe, nastoyashee i budushee (Burst Detector Sensitivity: Past, Present & Future) Authors: David L. Band Comments: To appear in the proceedings of the 16th Annual October Astrophysics Conference in Maryland, "Gamma Ray Bursts in the Swift Era", Washington DC., November 29-December 2, 2005, 4 pages, 3 figures Obsuzhdaetsya chuvstvitel'nost' razlichnyh detektorov gamma-vspleskov. K sozhaleniyu, dlya korotkih zhestkih vspleskov (dlya menya lichno eto interesno v svyazi s perspektivoi obnaruzheniya vnegalakticheskih gigantskih vspleskov MPG) nichego horoshego net: BATSE byl samym chuvstvitel'nym. A vot dlya dlinnyh myagkih vspleskov Swift namnogo luchshe. astro-ph/0601440 Otkrytie blizhaishego korichnevogo karlika? (Discovery of the Closest Brown Dwarf to the Sun? A Methane Rich Brown Dwarf around the Nearby M8.5 Star SCR 1845-6357) Authors: B.A. Biller, M. Kasper, L.M. Close, W. Brandner, S. Kellner Comments: 5 pages, 3 figures. Submitted to the Astrophysical Journal. Some figures are currently omitted and will be supplied with the final, accepted version V nachale - kur'ez. Pervyi raz ya vizhu, chtoby redaktory astro-ph propustili takoi glyuk, kak dvoinaya stat'ya: t.e. nomera 440 i 441 - eto odna i ta zhe rabota. Nadeyus', chto k sboyu v numeracii eto ne privedet. Teper' o suti. Po dannym nablyudenii na VLT u blizkoi zvezdy SCR 1845-6357 (8.5 pk ot Solnca) obnaruzhen kompan'on. Pohozhe, chto eto korichnevyi (buryi) karlik. Poka, razumeetsya, ne ustanovlena fizicheskaya svyaz' zvezdy i karlika (t.e. ne isklyucheno, chto eto fonovyi ob'ekt), no skoree vsego eto real'naya para. astro-ph/0601451 Otkrytie 35 novyh ostatkov sverhnovyh v central'noi chasti Galaktiki (Discovery of 35 New Supernova Remnants in the Inner Galaxy) Authors: C. L. Brogan, J. D. Gelfand, B. M. Gaensler, N. E. Kassim, T. J. Lazio Comments: 5 pages; Accepted to ApJL Po dannym obzora galakticheskoi ploskosti na VLA otkryto 35 novyh ostatkov sverhnovyh. Vse oni lezhat na galakticheskoi dolgote ot 4.5 do 22 gradusov, a po shirote v poyase +/-1.25 gradusov. My budem starat'sya hotya by perechislit' interesnye (dlya shirokoi publiki) stat'i, poyavivshiesya v razdele physics (vklyuchaya cross-listing). physics/0601138 Elektromagnitnyi kalorimetr BaBar: sostoyanie i modernizaciya (The BaBar Electromagnetic Calorimeter: Status and Performance Improvements) Authors: Johannes M.
