Chita et al. Comments: Accepted for publication in A&A Letters Vzaimodeistvie zvezdnyh vetrov, istekayushih na raznyh stadiyah ot evolyucioniruyushih massivnyh zvezd, mozhet porozhdat' prichudlivye struktury, poskol'ku geometriya i drugie parametry vetrov v razlichnye momenty zhizni zvezdy razlichayutsya. Avtory stroyat model' takih vetrov. V chastnosti, im udaetsya ob'yasnit' kartinu kolec vokrug praroditelya sverhnovoi 1987A bez privlecheniya dvoistvennosti. arxiv:0807.4036 Koncepciya proekta DUNE (Summary of the DUNE Mission Concept) Authors: Alexandre Refregier, Marian Douspis, the DUNE collaboration Comments: 9 pages; To appear in Proc. of SPIE Astronomical Telescopes and Instrumentation (23 - 28 June 2008, Marseille, France) Evropeiskoe kosmicheskoe agentstvo planiruet zapustit' opticheskii teleskop diametrom primerno 1.2 metra dlya kosmologicheskih issledovanii. Programma nazyvaetsya "Evklid". Poka idet otbor pretendentov, razrabatyvayushih konkretnye proekty. Posle nulevoi fazy otobrany proekty DUNE i SPACE. V stat'e rech' idet o DUNE. Po vsei vidimosti, missiya budet sovmeshat' v sebe dostoinstva "astronomicheskogo" i "uskoritel'nogo" podhodov. T.e., s odnoi storony, u missii est' chetko postavlennaya cel', s drugoi - ee realizaciya dast bol'shoi potok "pobochnyh" rezul'tatov vo vnegalakticheskoi astronomii. V stat'e dano obshee opisanie proekta. Bolee tehnicheskoe opisanie sm. v arxiv:0807.4037. arxiv:0807.4180 Klimat, prigodnyi dlya zhizni: rol' naklona osi vrasheniya (Habitable Climates: The Influence of Obliquity) Authors: David S. Spiegel, Kristen Menou, Caleb A. Scharf Comments: 34 pages, 13 figures, submitted to ApJ V formirovanii klimata vazhneishuyu rol' igraet naklon osi vrasheniya planety k ploskosti ee orbity vokrug zvezdy. U Zemli naklon osi v znachitel'noi stepeni stabilizirovan Lunoi. U ekzoplanet zemnogo tipa v poyasah obitaniya mogut byt' raznoobraznye naklony osi vrasheniya k ploskosti orbity, a v otsutstvie massivnyh sputnikov oni mogut izmenyat'sya. Vse eto ne sposobstvuet poyavleniyu i razvitiyu zhizni. Eto-to i issleduyut avtory. Obsudit' v ZhZh-soobshestve ru_astroph. Obsudit' na Astroforume v Nauchnoi panorame. arxiv:0807.4254 Sputnik AGILE (The AGILE Mission) Authors: M. Tavani, et al., for the AGILE Collaboration Comments: 20 pages, 26 figures. submitted to Astron. & Astrophys Sputnik AGILE vtoroi god kruzhitsya na orbite. Eto gamma-teleskop, rabotayushii v diapazone ot 30 MeV do 50 GeV (takzhe na bortu est' eshe i nebol'shoi rentgenovskii teleskop i nebol'shoi detektor gamma-vspleskov). Sravnivat' ego imeet smysl s priborom EGRET na bortu CGRO. AGILE obladaet bolee vysokim uglovym razresheniem i nizkoi cenoi pri prochih pochti ravnyh parametrah. Zapushennyi nedavno GLAST gorazdo moshnee AGILE, tak chto tut i sravnivat' nechego. V stat'e opisyvaetsya v osnovnom sam sputnik, ego pribory, rabota s dannymi i tp. Ni slova o poluchennyh za god s lishnim nauchnyh rezul'tatah tam net. No ob etom mozhno pochitat' na stranice proekta. obzor arxiv:0807.4870 Prilivnaya dissipaciya v dvoinyh sistemah (Tidal dissipation in binary systems) Authors: Jean-Paul Zahn Comments: 24 pages, 11 figures, lecture notes of "Stellar Physics Summer School 2005", on "Tidal effects in stars, planets and disks", EAS Publication Series 29, 2008 Svezhaya lekciya odnogo iz klassikov. Ona posvyashena prilivnoi dissipacii v tesnyh dvoinyh sistemah. Zvezdy vozbuzhdayut drug v druge prilivy. Dalee, v zavisimosti ot stroeniya zvezdy (vneshnyaya konvektivnaya, ili vneshnyaya luchistaya obolochka) energiya prilivov budet dissipirovat'. Eto vse ochen' vazhno dlya raschetov evolyucii dvoinyh sistem. miniobzor arxiv:0807.4871 Observatoriya imeni P'era Ozhe: rezul'taty po kosmicheskim lucham sverhvysokih energii (The Pierre Auger Observatory: Results on Ultra-High Energy Cosmic Rays) Authors: Johannes Bluemer for the Pierre Auger Collaboration Comments: 9 pages, Proceedings of the International Workshop on Advances in Cosmic Ray Science, Waseda University, Shinjuku, Tokyo, Japan, March 2008; to be published in the Journal of the Physical Society of Japan (JPSJ) supplement Ocherednaya svodka rezul'tatov ot observaotrii imeni Ozhe. Svodka polezna tem, chto summirovany vse dannye, ne tol'ko po osnovnoi komponente kosmicheskih luchei. Krome togo, avtor nemnogo rasskazyvaet o planah po stroitel'stvu severnoi chasti observatorii v SShA (pravda, on ne ochen' rasprostranyaetsya o finansovyh trudnostyah, s kotorymi stolknulsya proekt). Krome togo, v SShA u Ozhe est' konkurent, kotoryi nemnogo dal'she prodvinulsya v realizacii planov. Eto Telescope Array. miniobzor arxiv:0807.4929 Tochnoe izmerenie parametrov prohozhdenii planet (Measuring accurate transit parameters) Authors: Joshua N. Winn Comments: submitted to Proc. IAU Symp. No. 253, "Transiting Planets", eds. F. Pont et al., May 19-23, 2008, Cambridge, MA [11 pages] Pri prohozhdenii planety po disku zvezdy mozhno izmeryat' mnogo parametrov i nablyudat' mnogo raznyh effektov. V tablice v svoem nebol'shom obzore Vinn perechislyaet 26 parametrov i effektov. Chast' iz nih uzhe izmeryayut, chast' - budut izmeryat' v nedalekom budushem. Obzor nebol'shoi i ochen' ponyatnyi. Ne vse effekty, i ne vse puti izmereniya parametrov opisany, no dlya vseh dany ssylki. A te, kotorye opisany, opisany ochen' horosho. arxiv:0807.5013 Vysokotochnaya geometriya dvuhpolyusnogo pul'sara (High-precision geometry of a double-pole pulsar) Authors: M. Kramer, S. Johnston Comments: accepted for publication in MNRAS, 7 pages, 4 figures Avtory detal'no issleduyut interesnyi radiopul'sar, kotoryi, vozmozhno, stanet odnim iz rozettskih kamnei (odnim vryad li oboidutsya) dlya ponimaniya raboty pul'sarnogo mehanizma. Pul'sar B0906-49 demonstriruet dva impul'sa za period. Avtory nadezhno pokazyvayut, chto eto imenno impul'sy ot raznyh polyusov i tshatel'no issleduyut geometriyu ob'ekta. Dostoverno pokazano, chto istochnik yavlyaetsya ortogonal'nym rotatorom, t.e. ego magnitnaya os' perpendikulyarna osi vrasheniya. Opredelena vysota, na kotoroi voznikaet izluchenie (okolo 230 km). Avtory polagayut, chto istonik mozhet byt' zaregistrirovan GLAST v gamma-diapazone. Togda, v samom dele, eto budet otlichni probnyi kamen' dlya razrabotchikov teorii izlucheniya pul'sarov. arxiv:0807.5050 Sil'nye vzryvy pri z=0? (Powerful explosions at Z=0 ?) Authors: S. Ekstrom, G. Meynet, R. Hirschi, A. Maeder Comments: 5 pages, 5 figures, to appear in the IAU Symposium 255, "Low-Metallicity Star Formation: From the First stars to Dwarf Galaxies" Avtory pokazyvayut, chto zvezdy s nulevoi metallichnost'yu (v dannom sluchae z=0 oznachaet nulevuyu metallichnost', a ne krasnoe smeshenie) mogut davat' normal'nye vzryvy sverhnovyh. Dlya etogo neobhodimo, chtoby zvezdy dostatochno bystro vrashalis'. Obychno polagayut, chto massivnye zvezdy bez metallov porozhdayut ochen' tyazhelye uglerodno-kislorodnye yadra i pryamo kollapsiruyut v chernye dyry. Vrashenie mozhet izmenit' kartinu. Esli zvezdy pokoleniya III mogut davat' sverhnovye, to eto vazhno, t.k. vliyat na rannee obogashenie vselennoi tyazhelymi elementami. O vrashenie malometallichnyh zvezd sm. takzhe arxiv:0807.5061 My budem starat'sya hotya by perechislit' interesnye (dlya shirokoi publiki) stat'i, poyavivshiesya v razdele physics (vklyuchaya cross-listing). arxiv:0807.0087 Poslednie pokrovy imperatora? (The Emperor's Last Clothes?) Authors: A.N. Schellekens Comments: 87 pages Srazu nado skazat', chto avtor - izvestnyi teoretik-strunshik. V bol'shom esse rech' idet o mnogih "proklyatyh" voprosah v sovremennoi fizike. Mnogie iz nih predlagaetsya reshat' v ramkah teorii strun s primeneniem antropnogo principa. arxiv:0807.3670 Yavlyaetsya li vera vragom nauki? (Is Faith The Enemy Of Science?) Authors: Richard MacKenzie Comments: 9 pages, to be published in Physics of Canada Polemicheskoe esse na temu vzaimootnoshenii nauki i very (v shirokom smysle). Avtor zanimaet poziciyu, svoistvennuyu mnogim lyudyam v Rossii, polagaya, chto vera yavlyaetsya vragom nauki. Esse yavlyaetsya otvetom na doklad Kraussa, v kotorom on sformuliroval tezis: vera - ne vrag nauki, nevezhestvo - vrag. arxiv:0807.3706 Recenziya na knigu: Vozniknovenie Obshei teorii otnositel'nosti (Book review: The Genesis of General Relativity) Authors: Donald Salisbury Comments: 11 pages, to appear in General Relativity and Gravitation Daetsya recenziya na fundamental'nyi chetyrehtomnik, posvyashennyi rozhdeniyu i rannemu razvitiyu OTO. Recenziya interesna i sama po sebe, poskol'ku rech' idet ne tol'ko o knige, no i ob istorii OTO. Vernut'sya k nachalu stranicy
