    arxiv:0704.0171 Otkrytie tochechnogo istochnika gamma-kvantov ochen' vysokoi energii v Edinoroge (Discovery of a point-like very-high-energy gamma-ray source in Monoceros)
    Authors: F. Aharonian, et al
    Comments: 5 pages, 4 figures, to appear in A&A

    Ostatki sverhnovyh yavlyayutsya izvestnymi istochnikami vysokoenergichnyh chastic i gamma-kvantov. Poslednie voznikayut pri vzaimodeistvii chastic vysokih energii s veshestvom blizkih molekulyarnyh oblakov. Ostatok G 205.5+0.5 (Petlya v Edinoroge), nahodyashiisya na rasstoyanii primerno poltora kpk ot nas, yavlyaetsya horoshim ob'ektom dlya issledovaniya s pomosh'yu nazemnyh gamma-teleskopov, v chastnosti dlya H.E.S.S.

    V rezul'tate nablyudenii byl obnaruzhen tochechnyi istochnik gamma-kvantov (tochechnost' oznachaet, chto nikakoi struktury ne vyyavleno vplot' do nekotorogo uglovogo razmera, kotoryi v dannom sluchae sootvetsvuet lineinomu razmeru okolo 1 parseka). Priroda obnaruzhennogo istochnika poka neponyatna.

    Authors: Lawrence M. Krauss, Robert J. Scherrer
    Comments: 8 pages, submitted to 2007 Gravity Research Foundation Essay Competition

    Sobstvenno, eto ne original'naya stat'ya, a "esse na temu". Osnovnaya mysl' ego prosta i ponyatna. My zhivem k zamechatel'nuyu (pravda, dlinnuyu) epohu, kogda mozhno izuchat' kosmologiyu. V dalekom budushem, esli vselennaya budet takzhe uskorenno rasshiryat'sya, my budem videt' lish' nash "obitaemyi ostrov", a dal'nyaya vselennaya budet nedostupna dazhe dlya nablyudenii.

    Poskol'ku esse napisano ochen' yasno, to ya i obrashayu na nego vashe vnimanie.


    arxiv:0704.0238 Radioastrometricheskaya registraciya i izuchenie ekzoplanet (Radio Astrometric Detection and Characterization of Extra-Solar Planets: A White Paper Submitted to the NSF ExoPlanet Task Force)
    Authors: Geoffrey C. Bower et al.
    Comments: 7 pages

    Avtory rassmatrivayut, kak sushestvuyushie i budushie (SKA) radiointerferometry mogut pomoch' v poiske i izuchenii ekzoplanet. Uzhe sovremennye antenny pozvolyayut nadeyat'sya na obnaruzhenie planet, otkrytie i izuchenie kotoryh poka nevozmozhno drugimi sposobami. S vvodom v stroi SKA situaciya stanet eshe luchshe. Mozhno budet iskat' i issledovat' planety tipa Zemli na orbitah, podobnyh zemnoi.

    arxiv:0704.0460 Kilogradusnyi Predel'no Malen'kii Teleskop (KELT) (The Kilodegree Extremely Little Telescope (KELT): A Small Robotic Telescope for Large-Area Synoptic Surveys)
    Authors: Joshua Pepper et al.
    Comments: 31 pages, 13 figures; submitted to AJ

    Opisan ochen' malen'kii instrument, prednaznachennyi dlya poiska tranzitnyh (t.e. provohodyashih po disku svoei zvezdy) planet. Teleskop nazyvaetsya KELT - Kilodegree Extremely Little Telescope. Kak yasno iz nazvaniya on imeet ochen' malen'kuyu aperturu i shirokoe pole zreniya. Po suti, eto edva li ne prosto horoshaya CCD matrica (4096 na 4096) s ob'ektivom tipa togo, chto vy mozhete uvidet' u horoshego fotoapparata. Ob'ektivov dva, i oni dayut polya zreniya 26 na 26 i 10 na 10 gradusov. Instrument rabotaet s 2004 goda.

    Osnovnaya cel' - obnaruzhit' planetnye prohozhdeniya po diskam zvezd so zvezdnoi velichinoi ot 8 do 10. K nastoyashemu momentu vydeleno neskol'ko sobytii-kandidatov. Krome togo, v ramkah nablyudenii na KELT bylo otkryto okolo sotni novyh peremennyh zvezd.

    Stat'ya, navernoe, budet interesna "lyubitelyam-professionalam", a takzhe prosto professionalam, interesuyushimisya byudzhetnymi proektami.

    Authors: Francesca Matteucci
    Comments: 56 pages, Lectures delivered at the XVIII Canarie Winter School on "Emission Lines Universe"

    Ochen' detal'naya lekciya po himicheskoi evolyucii. Termin "himicheskaya evolyuciya" primenim, razumeetsya, v pervuyu ochered' ili k mezhzvezdnoi, ili k mezhgalakticheskoi srede. Vse eto v obzore est'. Est' tam eshe i opisanie razlichnyh processov, opredelyayushih etu evolyuciya. T.o., avtoru prihoditsya govorit' edva li ne o polovine vsei astrofiziki!

    Authors: E.P.J. van den Heuvel
    Comments: 9 pages. Invited talk at he Multicoloured Landscape of Compact Objects and their Explosive Origins', Cefalu', 2006 June 11-24 (AIP Conf. Proc.), eds. L. Burderi et al., i

    Izvestno 9 dvoinyh sistem, sostoyashih iz dvuh neitronnyh zvezd. S nimi svyazana odna zagadka. Slishkom mnogie iz nih imeyut malen'kie ekscentrisitety. Esli uchest', chto soglasno dannym po obychnym radiopul'saram neitronnye zvezdy rozhdayutsya s bol'shimi skorostyami (t.n. kik) poryadka 300-400 km/s, to malye ekscentrisitety predstavlyayutsya zagadochnymi. Po vsei vidimostim, te vzryvy sverhnovyh, kotorye privodyat (v srednem) k poyavleniyu odinochnyh pul'sarov i pul'sarov v massivnyh dvoinyh sistemah, razlichayutsya. Van den Hevel obsuzhdaet vozmozhnye puti resheniya zagadki. Na dannyi moment slozhilsya sleduyushii vzglyad. Vtorichnye komponenty massivnyh dvoinyh sistem ispytyvayut ne obychnyi vzryv sverhnovoi, svyazannyi s kollapsom zheleznogo yadra, a kollaps kislorodno-neonovo-magnievogo yadra. Veroyatnee vsego, eto yavlyaets isklyuchitel'noi osobennost'yu dvoinyh sistem. V odinochnyh zvezdah takie yadra v konce koncov prevrashayutsya v belye karliki.
