Obzory preprintov astro-ph Vypusk N131 astro-ph za 13 - 21 marta 2006 goda: izbrannye stat'i Goryachie temy nedeli Rezul'taty 3 let raboty WMAP Opublikovany rezul'taty obrabotki dannyh, poluchennyh za tri goda raboty sputnika WMAP. Poyavilos' srazu neskol'ko ochen' bol'shih rabot: astro-ph/0603449, astro-ph/0603450, astro-ph/0603451, astro-ph/0603452. Sensacii net. Rezul'taty sootvestvuyut dannym za prevyi god raboty, tol'ko tochnost' vozrosla, sootvetstvenno, vozrosla i tochnost' opredeleniya kosmologicheskih parametrov. Vazhno, chto polucheny dannye po polyarizacii reliktovogo izlucheniya. Oni pozvolyayut ustanovit' vazhnye verhnie predely na nravitacionnye volny. No zdes', vse-taki, nuzhno eshe zhdat' zapuska sputnika Planck, dlya kotorogo izuchenie polyarizacii relikta stanet osnovnoi zadachei, i tam mozhno ozhidat' uzhe ne tol'ko verhnih predelov. Referaty otdel'nyh statei astro-ph/0603257 Istoriya kosmologicheskogo zvezdoobrazovaniya: tri nezavisimyh podhoda (The History of Cosmological Star Formation: Three Independent Approaches and a Critical Test Using the Extragalactic Background Light) Authors: Kentaro Nagamine et al. Comments: 36 page, 9 figures. Submitted to ApJ Vsem ponyatno, chto istoriya zvezdoobrazovaniya vo vselennoi - eto vazhneishaya vesh'. Vyyasnit', kak zhe temp formirovaniya zvezd izmenyalsya, bolee chem slozhno. Sozdat' model', kotoraya horosho opisyvala by eti dannye, tozhe nelegko. Stat'ya ochen' interesnaya. Po-krainei mere vvodnuyu chast' i osnovnye rezul'taty stoit posmotret'. Pust' ob'em vas ne pugaet, eto sledstvie vybrannogo formata. Avtory rassmatrivayut tri podhoda: 1. Neposredstvennye dannye o dalekih ob'ektah. 2. Analiz svoist nashei i drugih blizkih galaktik. Takie "raskopki" mogut dat' informaciyu o tom, kakova byla istoriya zvezdoobrazovaniya v etih zvezdnyh sistemah. 3. Teoreticheskie modeli, osnovannye na detal'nom modelirovanii processa obrazovaniya galaktik i ih dal'neishei evolyucii. Vrode by, nablyudaetsya razumnyi konsensus treh podhodov (sm. risunok, na kotorom teoreticheskie modeli sravnivayutsya s nablyudeniyami). Vazhno, chto komp'yuternye modeli na osnovanii Lyambda-CDM podhoda takzhe horosho vpisalis'. Dve samye vazhnye detali - primernoe postoyanstvo tempa zvezdoobrazovaniya ot z=7 do 2, i spadanie ot z=2 do 0 - prisutstvuyut po vseh modelyah i v dannyh nablyudenii (na vsyakii sluchai napomnyu, chto dannye tut daleko ne neposredstvennye, fakticheski, nablyudaemye velichiny nado pereschityvat' model'no-zavisimym obrazom v temp zvezdoobrazovaniya). Pokazan temp zvezdoobrazovaniya v zavisimosti ot krasnogo smesheniya v edinicah massa Solnca v god na kubicheskii megaparsek. Shkala logarifmicheskaya s osnovanie 10. T.e. -2 sootvetstvuet 10-2=0.01 massy Solnca v god na kubicheskii megaparsek. Raznymi simvolami pokazany dannye nablyudenii. Krivye sootvetstvuyut razlichnym modelyam, obsuzhdaemym v tekste stat'i. astro-ph/0603266 O gorizontah i kosmicheskom peizazhe (On horizons and the cosmic landscape) Authors: George F R Ellis Comments: 4 pages "-Krepko ty menya popravil, Vasilii Ivanovich" Vsem chitat'! Pryamo vse v temu, t.e. v temu nashei s Toporenskim stat'i v tret'em nomere "Vokrug sveta". V proshlom vypuske ya obzorov ya rasskazyval o dvuh interesnyh stat'yah po tak skazat' interpretacionnoi kosmologii i vsyakih podvohah, i vot eshe odna. Eto kriticheskaya zametka, kommentarii, po povodu odnogo utverzhdeniya Sasskinda. Sut' v tom, chto Ellis polagaet, chto Sasskind v odnom meste svoei novoi populyarnoi knigi (vazhno, chto populyarnoi) putaet gorizont chastic s gorizontom sobytii. Eto lishnii raz pokazyvaet, kak vse neprosto, chto dazhe ochen' sil'nye i imenitye uchenye sporyat drug s drugom. Pravda, eshe raz obrashayu vnimanie, netochnost' obnaruzhena v populyarnoi knigi. V nekotorom smysle eto ne sovsem ex cathedra. astro-ph/0603335 Planety s vysokimi ekscentristetami po rezul'tatam anglo-avstraliiskoi programmy poiska planet (High eccentricity planets from the Anglo-Australian Planet Search) Authors: Hugh R. A. Jones et al. Comments: to appear in MNRAS Obnaruzheny dve planety s bol'shimi ekscentrisitetami. Dlya odnoi tochnoe znachenie poka ustanovit' trudno, t.k. period dovol'no dlinnyi - okolo 3 let - i kusok orbity v apoastre ne issledovan. A vot dlya vtoroi, s periodom vdvoe men'shim, udalos' poluchit' dostatochno tochnoe znachenie 0.92+/-0.03. Sm. takzhe svezhuyu stat'yu o poiske planet metodami mikrolinzirovaniya. Tam pokazano, chto planety s massami poryadka massy Neptuna na rasstoyanih v neskol'ko a.e. yavlyayutsya ochen' tipichnymi. kniga astro-ph/0603360 Pervyi svet (First Light) Authors: Abraham Loeb Comments: 158 pages, lecture notes for the SAAS-Fee Winter School, April 2006 (to be published by Springer Verlag); this http URL Eto chast' knigi s materialami ezhegodnoi shkoly po astronomii. Podrobno i dostupno opisyvaetsya, kak vo vselennoi iz pervichnyh fluktuacii poyavlyayutsya pervye ob'ekty, kak oni nachinayut izluchat', i chto s nimi potom proishodit. obzor astro-ph/0603372 Kosmicheskie neitrino ekstremal'no vysokih energii i reliktovye neitrino (Extremely High Energy Cosmic Neutrinos and Relic Neutrinos) Authors: Chris Quigg Comments: 19 pages, 11 figures in 19 files, uses pdproc.sty (included). Invited talk at NO-VE 2006, Neutrino Oscillations in Venice Est' nadezhda, chto novye ustanovki (IceCube, Auger, ...) smogut registrirovat' neitrino sverhvysokih energii. S reliktovymi neitrino slozhnee, no kogda-nibud' i ih nauchat'sya lovit'. Obo vsei etoi nauke (i ob astrofizicheskoi chasti, i o tehnicheskoi, i o fizike mezhdu nimi) mozhno prochest' v obzore. obzor astro-ph/0603376 Kogda ekzoplanety prohodyat na fone svoih zvezd (When Extrasolar Planets Transit Their Parent Stars) Authors: David Charbonneau et al. Comments: Review Chapter for Protostars and Planets V, 16 pages, 4 figures Est' neskol'ko metodov poiska i issledovaniya ekzoplanet: mikrolinzirovanie, kolebaniya zvezdy otnositel'no centra mass sistemy, prohozhdenie ekzoplanet po disku zvezdy. Vot poslednemu metodu i posvyashen obzor. Metod etot odin iz luchshih. Ved' v sluchae linzirovaniya my vidim razovoe sobytie, i mnogo informacii tak ne poluchish'. Po kolebaniyam zvezdy mozhno uznat' orbital'nyi period i massu planety, no est' mnogo slozhnostei. A vot nalichie prohozhdenii pozvolyaet vytyagivat' massu informacii. Naprimer, mozhno vydelit' svet planety (etomu bylo posvyasheno mnogo interesnyh rabot, o nekotoryh ya pisal v obzorah, sm. takzhe punkt 4 zdes'). Tak chto metod ochen' perspektiven. Chitaite! kniga astro-ph/0603390 Dzhety i sverhkriticheskii akkrecionnyi disk u SS433 (The Jets and and Supercritical Accretion Disk in SS433) Authors: Sergei Fabrika Comments: 100 pages, 19 figures; Astrophysics and Space Physics Reviews (2004), 12, pp. 1-153 Sergei Fabrika iz SAO davno i uspeshno zanimaetsya izucheniem sistemy SS433. I vot, napisal o nei celuyu knigu. Konechno, rech' tam ne tol'ko ob odnom edinstvennom ob'ekte. Mnogie soobrazheniya primenimy i k drugim istochnikam, naprimer k ul'tramoshnym rentgenovskim istochnikam. Sergei schitaet, chto oni yavlyayutsya analogami SS433. miniobzor astro-ph/0603399 Otkryvaya novoe okno dlya fundamental'noi fiziki i astrofiziki: rentgenovskaya polyarimetriya (Opening a New Window to Fundamental Physics and Astrophysics: X-ray Polarimetry) Authors: E. Costa et al. Comments: 8 pages 1 table 14 figures; Proc. 39th ESLAB Symposium, Noordwijk, 19-21 April 2005, SP-588, p. 141-149, F. Favata, A. Gimenez. eds Chasto mozhno uslyshat', chto vozmozhnost' registrirovat' polyarizaciyu rentgenovskogo izlucheniya, ochen' vazhna dlya sovremennoi astrofiziki (u nas v strane odnim iz luchshih specialistov zdes' yavlyaetsya Yurii Gnedin iz Pulkovo). A vot pochemu eto tak vazhno, i kakie tut est' blizhaishie perspektivy, vy mozhete uznat' iz obzora. astro-ph/0603444 Massa Dzhinsa i proishozhdenie izloma v nachal'noi funkcii mass (The Jeans mass and the origin of the knee in the IMF) Authors: I. A. Bonnell et al. Comments: 6 pages, 4 figures, MNRAS in press Na osnovanii chislennyh raschetov avtory prihodyat k vyvodu o tom, chto nalichie izloma v nachal'noi funkcii mass i ego mestopolozhenie (na massah poryadka solnechnoi) opredelyaetsya ne nachal'nymi usloviyami v szhimayushemsya oblake, a mehanizmom ohlazhdeniya. Sm. takzhe obzor, posvyashennyi problemam v izuchenii nachal'noi funkcii mass. astro-ph/0603449 Rezul'taty treh let raboty WMAP: prilozheniya k kosmologii (Wilkinson Microwave Anisotropy Probe (WMAP) Three Year Results: Implications for Cosmology) Authors: D.

Jarosik et al. Comments: 49 pages, 13 figures, submitted to ApJ Vse ih tak zhdali, i vot oni! Rezul'taty obrabotki dannyh po itogam treh let nablyudenii na sputnike WMAP! (izobrazhenie vzyato s saita Universetoday.com) Bolee podrobno obo vsem etom mozhno prochest' zdes'. miniobzor astro-ph/0603501 Novye rezul'taty po gamma-astronomii vysokih energii (New Results from High Energy Gamma-Ray Astronomy) Authors: Heinrich J. Vlk Comments: 10 pages, 6 figures, Invited paper at IAU Symposium No.230, 2005, in Dublin (Ireland); E.J.A. Meurs, G. Fabbiano, eds.; in press (2006) Opisany novye rezul'taty, poluchennye na nazemnyh (cherenkovskih) gamma-teleskopah tipa H.E.S.S. i MAGIC. Nekotorye rezul'taty v etoi zhe oblasti, svyazannye s obolochechnymi ostatkami sverhnovyh, mozhno naiti v drugom obzore togo zhe avtora astro-ph/0603502. astro-ph/0603520 Vega - bystrovrashayushayasya zvezda (Vega is a rapidly rotating star) Authors: D. M. Peterson et al. Comments: 10 pages, 2 figures, a Letter to Nature, tentatively scheduled for April 13 Vega - odna iz dvuh samyh yarkih zvezd severnogo neba. Krome togo, ona ispol'zuetsya v kachestve standarta. Tem ne menee, nekotorye ee svoistva postoyanno utochnyayutsya. V chastnosti, davno bylo zamecheno, chto Vega neskol'ko yarche, chem pohozhie na nee zvezdy. Polagali, chto eto mozhet byt' svyazano s tem, chto 1. Zvezda bystro vrashaetsya 2. My vidim ee pochti s polyusa. I vot udalos' pokazat', chto eto v samom dele tak. S pomosh'yu interferometricheskih nablyudenii udalos' vyyavit' raspredelenie yarkosti po vidimoi poverhnosti Vegi (sm . risunok). Ot polyusa k ekvatory temperatura spadaet na 2400 gradusov! Chtoby eto ob'yasnit', trebuetsya predpolozhit' bystroe vrashenie. Ved' togda zvezda budet splyusnutoi, a znachit, ekvator budet holodnee, chem polyarnye oblasti. Pri etom skorost' ochen' velika, na ekvatore ona dostigaet 270 km/s. Esli ona byla by bol'she hotya by na 8 procentov, to veshestvo nachalo by ottekat' ot ekvatora zvezdy. Primerno tak vidna Vega s Zemli. Novye nablyudeniya pozvolili utochnit' parametry Vegi. Massa ravna primerno 2.3 massy Solnca. Vozrast 386 +/- 16 millionov let. Eto chut' bol'she, chem polagalos' ranee (hotya v predelah oshibok znacheniya i sovpadayut). Odnako, eti znacheniya chuvstvitel'ny k predpolozheniyam o himicheskom sostave Vegi, tak chto oni eshe mogut utochnit'sya v budushem. My budem starat'sya hotya by perechislit' interesnye (dlya shirokoi publiki) stat'i, poyavivshiesya v razdele physics (vklyuchaya cross-listing). physics/0603095 Fiziki v voennoe vremya (Physicists in times of war) Authors: Bert Schroer Comments: 16 pages Nazvanie neskol'ko sbivaet s tolku. Rech' idet nemnogo o drugom. Rech' idet o vybore zhiznennoi pozicii, o politicheskom vybore, v ochen' neprostoe vremya. Osnovnaya chast' stat'i posvyashena izvestnomu nemeckomu fiziku 'ordanu (Jordan) i ego vzaimootnosheniyam s kollegami. physics/0603112 Teoriya strun i krizis v teorii elementarnyh chastic (String theory and the crisis in particle physics) Authors: Bert Schroer Comments: 30 pages Kriticheskoe esse o teorii strun. Kstati, odnoi iz motivacii dlya ego napisaniya stala novaya populyarnaya knigu Sasskinda (Susskind), o kotoroi ya ranee upominal. Krome kriticheskoi chasti esse interesno istoricheskim vvedeniem. quant-ph/0603146 Ser Artur Eddington i osnovy sovremennoi fiziki (Sir Arthur Eddington and the Foundations of Modern Physics) Authors: I.
