Obzory preprintov astro-ph Vypusk N156 astro-ph za 24 - 30 aprelya 2007 goda: izbrannye stat'i Referaty otdel'nyh statei arxiv:0704.2667 Krotovye nory kak dvoiniki chernyh dyr (Wormholes as Black Hole Foils) Authors: Thibault Damour, Sergey N. Solodukhin Comments: 13 pages, no figures, Latex V vpolne dostupnoi stat'e avtory rassmatrivayut vopros o tom, mozhno li s tochki zreniya sovremennyh nablyudenii razlichit' chernye dyry i krotovye nory. Okazyvaetsya, chto sdelat' eto prakticheski nevozmozhno. Vse upiraetsya v to, chto kak obychno prodemonstrirovat' sushestvovanie gorizonta u real'nogo astronomicheskogo ob'ekta kraine tyazhelo. Podrobnee ob etoi stat'e sm. v novostyah nauki na saite Grani.ru. arxiv:0704.3031 Kornel'sko-Kaltehovskii Teleskop v Atakame (The Cornell Caltech Atacama Telescope) Authors: Simon J. E. Radford, Riccardo Giovanelli, Thomas A. Sebring, Jonas Zmuidzinas Comments: 6 pages, 18th International Symposium on Space Terahertz Technology Rech' idet o proekte 25-metrovogo teleskopa, rabotayushego v submillimetrovoi oblasti, kotoryi planiruetsya razmestit' v pustyne Atakama. Nazyvaetsya proekt CCATS - Cornell Caltech Atacama Telescope. K sozhaleniyu, v stroi instrument vstupit ochen' i ochen' neskoro. Razgovor poka idet o 2012 gode. arxiv:0704.3059 Poisk analogov Solnechnoi sistemy s pomosh'yu SIM i Hipparcos (Finding Solar System Analogs With SIM and HIPPARCOS: A White Paper for the ExoPlanet Task Force) Authors: Rob P. Olling Comments: A White Paper for the ExoPlanet Task Force: 7 pages Ideya avtora sostoit v tom, chtoby ispol'zovat' dannye budushego sputnika SIM i uzhe otletavshego sputnika Hipparcos dlya poiska massivnyh planet i korichnevyh karlikov na shirokih orbitah. Pri orbital'nom periode v desyatki i sotni let ochen' trudno rasschityvat' na kakoi-to rezul'tat za vremya zhizni sputnika (3-7 let). Odnako dannye s dvuh astrometricheskih sputnikov, otrabotavshih s intervalom let v dvadcat', uzhe mogut dat' neobhodimuyu tochnost'. Ocenki pokazyvayut, chto sovmestnaya obrabotka dannyh dvuh apparatov pozvolit obnaruzhit' planetu s massoi kak u Yupitera dazhe dlya orbital'nyh periodov v 240 let. A pri masse v dest' raz bol'she - 500 let. miniobzor arxiv:0704.3171 Proishozhdenie rentgenovskogo izlucheniya zvezd T Tel'ca (The origin of X-ray emission from T Tauri stars) Authors: Thomas Preibisch Comments: 8 pages, Review talk at the Conference "Coronae of Stars and Accretion Disks", Bonn, Germany, December 2006. Conference proceedings to be published in Memorie della Societa Astronomica Italiana Zvezdy tipa T Tel'ca - eto molodye ob'ekty, eshe nahodyashie na stadii formirovaniya. Oni izvestny kak istochniki rentgenovskogo izlucheniya. Nedavnie usiliya po nablyudeniyam etih istochnikov na Chandre priveli k luchshemu ponimaniyu processov, privodyashih k izlucheniyu. Odnako polnoi yasnosti net. Vsemu etomu i posvyashen obzor. Osnovnye vyvody avtora takovy: 1. Vse zvezdy T Tel'ca proyavlyayut povyshennuyu aktivnost' a rentgene (vne zavisimosti ot massy) 2. Osnovnaya dolya rentgenovskogo izlucheniya svyazana s koronal'noi aktivnost'yu 3. Dolya, za kotoruyu otvetstvenna akkreciya, mala. obzor arxiv:0704.3374 Geometriya i topologiya v relyativistskoi kosmologii (Geometry and Topology in Relativistic Cosmology) Authors: Jean-Pierre Luminet Comments: 14 pages, invited talk given at "More geometrico" Conference, 3-4 may 2005, Milano University (Italy), to be published in Proceedings "New Trends in Geometry, and Its Role in the Natural and Life Sciences", eds. C. Bartocci, L. Boi & C. Sinigaglia, Elsevier Rassmotren matematicheskii aspekt klassifikacii vozmozhnyh vselennyh. Nablyudatel'nye testy obsuzhdayutsya v osnovnom v kontekste rezul'tatov WMAP po reliktovomu fonu.

(Helioseismic analysis of the solar flare-induced sunquake of 2005 January 15) Authors: H. Moradi, A. -C. Donea, C. Lindsey, D. Besliu-Ionescu, P. S. Cally Comments: 12 pages, 7 figures, published in MNRAS 374, 1155-1163 (2007) Opisany otkrytie i nablyudenie odnogo iz samyh moshnyh solncetryasenii. Akusticheskie kolebaniya byli, po vsei vidimosti, zapusheny za schet energii chastic, uskorivshihsya vo vspyshke. obzor arxiv:0704.3540 Inflyacionnye vozmusheniya: kosmologicheskii effekt Shvingera (Inflationary Perturbations: the Cosmological Schwinger Effect) Authors: Jerome Martin Comments: 49 pages, 6 figures, to appear in a LNP volume "Inflationary Cosmology" Avtor nazyvaet svoi obzor "pedagogicheskim vvedeniem v teoriyu inflyacionnyh kosmologicheskih kvantovo-mehanicheskih vozmushenii". Eto "obzor ne dlya vseh": v nem okolo 200 neprostyh formul. Tak chto pedagogicheskii harakter sostoit v tom, chto vvedenie deistvitel'no podrobnoe, no vse eto dlya teh, kto real'no zanimaetsya sootvestvuyushei naukoi, provodya real'nye raschety. arxiv:0704.3543 Rezul'taty po poisku temnoi materii i dvoinomu beta-raspadu v eksperimente DAMA v Gran Sasso (Results on Dark Matter and beta beta decay modes by DAMA at Gran Sasso) Authors: R.

Nablyudeniya prodolzhayutsya, no nadezhdy, esli chestno, ne ochen' mnogo.

Magno Eshe odin obzor ot Zhana-P'era Lyumine. Na etot raz on posvyashen istorii razvitiya kosmologicheskih teorii. Nachinaetsya vse s 1917 goda i proslezhivaetsya do samogo poslednego vremeni.

Prichem, rech' idet ne tol'ko ob UHECR (t.e. o luchah s energiei za 1019> eV, no i chasticah na paru poryadkov menee energichnyh). V kachestve populyarnogo vvedeniya (na russkom) mogu porekomendovat' svezhuyu stat'yu v Vokrug Sveta.

Goldstein Comments: 14 pages, 9 figures, for Proceedings ISSP Erice 2006 Eto biograficheskaya stat'ya, posvyashennaya izvestnomu fiziku-teoretiku Richardu Dalitcu (inogda pishut Dalic). Dalitc rodilsya i vyros v Avstralii, a svoyu nauchnuyu rabotu nachal v Kembridzhe v seredine 20 veka. Naibolee izvestna ego "diagramma Dalitca" (Dalitz plot). Eta diagramma? vvedennaya Dalitcem pri rassmotrenii raspadov K-mezonov, kraine udobna dlya issledovaniya troinyh raspadov chastic. Vernut'sya k nachalu stranicy </
