    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. Razumeetsya, avtor govorit o zashishaemoi im modeli.


    arxiv:0704.3472 Gelioseismologicheskii analiz solncetryaseniya, vyzvannogo vspyshkoi 15 yanvarya 2005 g. (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. Bernabei
    Comments: 14 pages, Contributed paper to Neutrinoless Double Beta Decay (NDBD07), Ahmedabad (India), February 2007

    "Ishut, no tak i ne mogut naiti" (s)
    V stat'e opisany prodolzhayushiesya poiski redkih sobytii v podzemnom eksperimente DAMA v Italii. Nablyudeniya prodolzhayutsya, no nadezhdy, esli chestno, ne ochen' mnogo. Hotya, predely vse vremya uluchshayutsya, i dlya ogranichenii na fantaziyu teoretikov eto vse ochen' vazhno.


    obzor arxiv:0704.3579 Razvitie modelei Bol'shogo vzryva: ot mifa k teorii i nablyudeniyam (The Rise of Big Bang Models, from Myth to Theory and Observations)
    Authors: Jean-Pierre Luminet
    Comments: 15 pages, pdf only. Invited talk at conference "Antropogenesi : Dall'energia al fenomeno umano", 19-21 october, Portogruaro (Italy). To appear in Proceedings, eds. A. Pavan, E. 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. Osoboe vnimanie avtor udelyaet ideyam Lemetra, kotorye, na vzglyad Lyumine, vo mnogom nedooceneny.


    obzor arxiv:0704.3721 Kosmicheskie luchi: vtoroe koleno i dalee (Cosmic Rays: The Second Knee and Beyond)
    Authors: Douglas R Bergman, John W. Belz
    Comments: 46 pages, 30 figures. Topical Review to appear in J. Physics G

    Zamechatel'nyi podrobnyi obzor, posvyashennyi eksperimentam v oblasti kosmicheskih luchei sverhvysokih energii. 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.




    My budem starat'sya hotya by perechislit' interesnye (dlya shirokoi publiki) stat'i, poyavivshiesya v razdele physics (vklyuchaya cross-listing).


    arxiv:0704.3966 Dik Dalitc: primery ego vklada v fiziku elementarnyh chastic (Dick Dalitz: Examples of His Contributions to Particle Physics)
    Authors: Gary R. 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.
