Referaty otdel'nyh statei
Authors: J. Anthony Tyson, for the LSST Collaboration Comments: 9 pages, 3 figures, Talk given at CIPANP 2006, 9th Conference on the Intersections of Particle and Nuclear Physics, May 30-June 3, 2006, Rio Grande, Puerto Rico LSST (Large Synoptic Survey Telescope) nachnet svob rabotu v 2013 godu. Eto nazemnyi vos'mimetrovyi teleskop s bol'shim polem zreniya. Kak i u vseh instrumentov etogo tipa (nachinaya s 8-mi santimetrovyh) spisok ego zadach ves'ma shirok: ot malyh tel solnechnoi sistemy do kosmologii. V dannoi stat'e rech' idet imenno o poslednei. Nablyudeniya mnozhestva slabyh galaktik pozvolyat poluchit' vazhnuyu informaciyu o svoistvah krupnomasshtabnoi struktury. Eto, v svoyu ochered', pozvolit luchshe ponyat' svoistva temnoi materii i temnoi energii.
Authors: D.D. Frederiks, et al. Comments: 11 pages, 4 figures, accepted for publication in Astronomy Letters MPG - eto istochniki myagkih povtoryayushihsya gamma-vspleskov. V nashei Galaktike ih izvestno tri, plyus eshe odin v Magellanovom oblake, plyus est' kandidaty. Inogda eti istochniki dayut moshnye, t.n. gigantskie, vspyshki. Po svoim svoistvam oni pohozhi na korotkie gamma-vspleski (kotorye, veroyatnee vsego svyazany so sliyaniyami neitronnyh zvezd). Konechno, kosmicheskie gamma-vspleski moshnee gigantskih vspyshek, no vremennye i spektral'nye svoistva ochen' blizki. Poetomu vspyshku magnitara v ne ochen' dalekoi galaktike mozhno pereputat' s korotkim gamma-vspleskom. V stat'e avtory opisyvayut nablyudeniya vspleska GRB 051103. Na nebe on popadaet v oblast', gde nahoditsya izvestnaya galaktika M81. Sootvetstvenno, voznikaet mysl' o tom, chto my mozhem videt' gigantskuyu vspyshku magnitara. Avtory polagayut, chto tak ono i est'. K takim zhe vyvodam prihodyat v svoei stat'e Ofek i dr. Podrobnee ob etom otkrytii mozhno prochest' v ANKe Dnya na saite Elementy.Ru ili zdes'.

Authors: Orfeu Bertolami Comments: Chapter in the book Relativity and the Dimensionality of the World to be published in the Springer series Fundamental Theories of Physics. Volume Editor: Vesselin Petkov. 18 pages plus macros; updated references Interesnoe chtenie dlya teh, kto ser'ezno interesuetsya sovremennym sostoyaniem izucheniya svoistv prostranstva-vremeni. Stat'ya nachinaetsya s istoricheskogo vvedeniya, no dazhe ono uzhe soderzhit formuly. Tak chto eto ne legkoe chtivo. Osnovnoe vnimanie udeleno sovremennym rabotam, sootvetstvenno, daetsya dostatochno mnogo ssylok.
Authors: F. K. Roepke et al. Comments: 8 pages, 4 figures, to appear in the Proceedings of the 13th General Meeting of the European Physical Society, Bern 11-15 July 2005 Nebol'shoi obzor posvyashen kak teorii, tak i nablyudeniyam sverhnovyh tipa Ia. Osnovnoi temoi yavlyayutsya chislennye raschety vzryvov i ih sravnenie s nablyudeniyami. Stat'ya napisano ochen' yasno i posledovatel'no. Nesmotrya na opisanie teorii formul prakticheski net. Uchityvaya vazhnost' sverhnovyh tipa Ia dlya sovremennoi astrofiziki i kosmologii, vsem sovetuyu hotya by prosmotret' obzor.
Authors: James M. Cline Comments: 64 pages, many figures; lectures at Les Houches Summer School, Session 86: Particle Physics and Cosmology: the Fabric of Spacetime, 7-11 Aug. 2006. Bol'shoi obzor (tochnee, tekst lekcii), posvyashennyi probleme barionnoi asimmetrii Vselennoi. Pervye stranic shest' teksta soderzhat horoshee legko chitaemoe vvedenie. Potom nachinaetsya bolee ser'eznyi material.
Authors: M. Gritschneder, T. Naab, F. Heitsch, A. Burkert Comments: 4 pages, 2 figures. To appear in: "Triggered Star Formation in a Turbulent ISM", IAU Symposium 237, Prague, Czech Republic, August 2006; eds. B.G.Elmegreen & J. Palous S pomosh'yu chislennogo modelirovaniya avtory pokazyvayut, chto ioniziruyushee izluchenie massivnyh molodyh zvezd sposobno inducirovat' zvezdoobrazovanie v blizkih molekulyarnyh oblakah.
Authors: Sloane J. Wiktorowicz, Andrew P. Ingersoll Comments: 31 pages, 11 figures, accepted for publication in Icarus Rassmotrena vozmozhnost' nalichiya zhidkoi vody na Urane i Neptune. Pokazano, chto na Neptune zhidkoi vody byt' ne dolzhno.
Authors: Marta Volonteri Comments: 9 pages, Invited review at the Sixth International LISA Symposium Obzor napisan dlya konferencii, posvyashennoi proektu LISA, poetomu osnovnoi material uvyazyvaetsya s izlucheniem gravvoln. Odnako iz bez nih tam est' chto obsudit'. Sobstvenno, osnovnoi temoi yavlyaetsya sleduyushii process. V hode ierarhicheskogo skuchivaniya, kogda iz pervonachal'nyh nebol'shih galo "na odnu zvezdu" formiruyutsya galaktiki, ih skopleniya i t.p., proishodit mnozhestvo aktov sliyaniya chernyh dyr. Delo v tom, chto pervye zvezdy, poyavlyayushiesya v etih pervichnyh galo, v osnovnom dolzhny porozhdat' imenno chernye dyry. Nachav s mass poryadka 100-200 mass Solnca, chernye dyry bystro "polneyut", i, esli na nih idet akkreciya, my mozhem nablyudat' ih kak kvazary na bol'shih krasnyh smesheniyah.
Authors: S. Geier et al. Comments: 10 pager, 11 figures, Astronomy & Astrophysics accepted Sobstvenno, stat'ya privlekla moe vnimanie potomu, chto obsuzhdaemaya sistema schitaetsya odnim iz luchshih (na segodnyashnii den') kandidatov v budushie sverhnovye tipa Ia. Odnako takoi vyvod nuzhdaetsya v detal'nom nablyudatel'nom podtverzhdenii. Dlya etogo nado pokazat', chto, vo-pervyh, sistema sostoit iz "nuzhnyh" zvezd, a vo-vtoryh, chto ih summarnaya massa prevoshodit chandrasekarovskii predel. Avtory pokazali, chto priroda kompan'onov udovletvoryaet trebovaniyam, pred'yavlyaemym k praroditelyam sverhnovyh Ia. S summarnoi massoi vse slozhnee. Delo v tom, chto ona okazalas' ochen' blizka k kriticheskoi. No vot s kakoi storony? Avtory polagayut bolee veroyatnym, chto massa vse-taki prevoshodit chandrasekarovskuyu. I, t.o., KPD 1930+2752 v samom dele yavlyaetsya edva li ne luchshim kandidatom v budushie sverhnovye.
Authors: Michael J. Kurtz et al. Comments: 2 pages, To appear in Library and Information Systems in Astronomy V V vidu svoei chrezmernoi kratkosti (2 stranicy) stat'ya ne slishkom informativna. Odnako v nei po krainei mere upomyanuty vazhneishie tendencii i blizhaishie celi v razvitii nauchnyh bibliotek.
Authors: Jill C. Tarter, et al. Comments: To be published in Astrobiology. 34 pages Navernoe, esli poyavlyaetsya bol'shaya stat'ya po obitaemosti planet, pervym avtorom kotoroi yavlyaetsya Dzhill Tarter, to ee uzhe stoit chitat'. Sut' stat'i sostoit v analize vozmozhnosti sushestvovaniya obitaemyh planet vokrug malomassivnyh zvezd. Aktual'nost' ochevidna, ved' M-karliki sostavlyayut bol'shinstvo zvezdnogo naseleniya. Obychno polagayut, chto sochetanie nizkoi svetimosti s vysokoi vspyshechnoi aktivnost'yu delaet eti zvezdy neprivlekatel'nymi s tochki zreniya poiska zhizni na planetah, vrashayushihsya vokrug nih. Tarter i ee kollegi provodyat detal'nuyu pereocenku vozmozhnosti sushestvovaniya obitaemyh planet vokrug krasnyh karlikov i prihodyat v vyvodu, chto, hotya nalichestvuyut processy, prepyatstvuyushie poyavleniyu zhizni, tem ne menee, sovsem sbrasyvat' so schetov eti tusklye solnca rano.
Authors: Guillermo Gonzalez Comments: 30 pages, invited review paper for PASP Podrobnyi obzor, posvyashennyi tomu, kak vydelyayutsya svoim himicheskim sostavom zvezdy, vokrug kotoryh obnaruzheny ekzoplanetnye sistemy.
My budem starat'sya hotya by perechislit' interesnye (dlya shirokoi publiki) stat'i, poyavivshiesya v razdele physics (vklyuchaya cross-listing).
Authors: Sacha E. Kopp Comments: 86 pages, lecture notes Vashemu vnimaniyu predlagayutsya lekcii po generacii neitrinnyh puchkov na uskoritelyah. Razumeetsya, sami neitrino poluchayut posle oblucheniya puchkom chastic (obychno protonov) nekotoroi misheni. Seichas vse eto osobenno interesno, poskol'ku idut neitrinnye eksperimenty s dlinnoi bazoi. V nih puchok neitrino s kakogo-nibud' uskoritelya (naprimer, v CERNe) napravlyatsya skvoz' Zemlyu za sotni kilometrov na apparaturu kakogo-nibud' neitrinnogo eksperimenta (naprimer, Borexino v Gran Sasso). Eto pozvolit poluchit' principial'no novye dannye po neitrinnym oscillyaciyam. Tak chto tema bolee chem aktual'na.
