    arxiv:0712.1871 Vse li massivnye zvezdy rozhdayutsya v OV associaciyah i skopleniyah? (Were All Massive Stars Born in OB Associations and Clusters?)
    Authors: You-Hua Chu, Robert A. Gruendl
    Comments: 8 pages, 6 figures, Massive Star Formation: Observations Confront Theory, held at Heidelberg on September 10-14, 2007

    Postoyanno obsuzhdaetsya vopros o tom, vse li massivnye zvezdy rodilis' v skopleniyah ili associaciyah. Avtory proveli podrobnyi analiz molodyh zvezdnyh ob'ektov v Bol'shom Magellanovom oblake s pomosh'yu kosmicheskogo IK-teleskopa im. Spitcera. Pokazano, chto 65 procentov massivnyh zvezd rozhdaetsya v associaciyah, 85 - v giganstkih molekulyarnyh oblakah (razumeetsya, nichto ne meshaet zvezde vnesti vklad i tuda, i tuda), i lish' okolo 7 procentov - sovsem odinoki. Eto nahoditsya v soglasii s analogichnoi ocenkoi dlya Galaktiki, gde, kak polagayut, 5-10 procentov massivnyh zvezd rozhdayutsya vne skoplenii ili associacii.


    arxiv:0712.2162 Relyativistskie modeli magnitarov: struktura i deformacii (Relativistic models of magnetars: structure and deformations)
    Authors: A. Colaiuda, V. Ferrari, L. Gualtieri, J.A. Pons
    Comments: 25 pages, 9 figures, submitted to MNRAS

    Avtory rassmatrivayut, kak magnitnye polya razlichnoi konfiguracii deformiruyut neitronnye zvezdy. Konechno, mnogie parametry izvestny ploho (topologiya polya, ego raspredelenie vnutri zvezdy), poetomu raschety v sushestvennoi stepeni model'nye.

    Dlya nablyudaemyh magnitarov (u nih dlinnye periody vrasheniya) iskazheniya formy za schet magnitnogo polya sil'nee, chem za schet vrasheniya. Eto vazhno dlya evolyucii etih ob'ektov (naprimer, mozhet izmenyat'sya ugol mezhdu magnitnoi os'yu i os'yu vrasheniya) i izlucheniya imi gravitacionnyh voln. A vot pri periodah poryadka desyatyh dolei sekundy dazhe magnitarnye polya dayut iskazhenie slabee, chem vrashenie. Pravda, vazhno, chto iskazheniya eti raznye. Vrashenie tol'ko splyushivaet zvezdu vdol' osi vrasheniya. A pole v zavisimosti ot topologii mozhet davat' prakticheski lyubye iskazheniya formy.


    miniobzor arxiv:0712.2209 Central'nye kompaktnye ob'ekty v ostatakah sverhnovyh (Central Compact Objects in Supernova Remnants)
    Authors: Andrea De Luca
    Comments: 9 pages. Invited talk at the conference "40 Years of Pulsars: Millisecond Pulsars, Magnetars and More", August 12-17, 2007, Montreal (CA). To appear in the proceedings, ed. by C.Bassa, Z.Wang, A.Cumming and V.Kaspi, AIP, in press

    Nebol'shoi obzor poslednih rezul'tatov po kompaktnym rentgenovskim istochnikam v ostatkah sverhnovyh. Napomnyu sut' problemy. Seichas my vidim v ostatkah okolo desyatka istochnikov, kotorye navernyaka (v nekotoryh sluchayah "pochti navernyaka") yavlyayutsya neitronnym zvezdami. Desyatok - eto ne malo. Radiopul'sarov, nadezhno associirovannyh s ostatkami primerno stol'ko zhe. Tak vot, kompaktnye istochniki eti na radiopul'sary sovsem ne pohozhi. T.e., kak minimum polovina neitronnyh zvezd dolzhna rozhdat'sya "inymi". Andrea privodit novye nablyudatel'nye rezul'taty i obsuzhdaet razlichnye gipotezy, vyskazannye po povodu etih rezul'tatov. Osobenno detal'no opisyvayutsya dannye po istochniku v ostatke RCW 103 i istochniku 1E 1207.


    arxiv:0712.2460 Modelirovanie sliyanii chernyh dyr i neitronnyh zvezd s polnym uchetom effektov OTO (Fully General Relativistic Simulations of Black Hole-Neutron Star Mergers)
    Authors: Zachariah B. Etienne et al.
    Comments: 22 pages, 14 figures, submitted to Phys.Rev.D

    Avtory predstavlyayut rezul'taty chislennogo modelirovaniya sliyaniya chernoi dyry i neitronnoi zvezdy, poluchennye s pomosh'yu novogo koda. Napomnyu, chto takie sobytiya vo-pervyh, sovershenno tochno yavlyayutsya moshneishimi istochnikami gravitacionnyh voln (i, skoree vsego, LIGO pervymi uvidit imenno ih), a vo-vtoryh, kakoe-to vremya takie sobytiya obsuzhdalis' kak istochniki korotkih gamma-vspleskov.

    Rezul'taty podtverzhdayut, chto gamma-vsplesk sdelat' trudno, t.k. pochti vse veshestvo neitronnoi zvezdy srazu provalivaetsya v dyru, i lish' zhalkie procenty idut na obrazovanie diska. Razumeetsya, avtory rasschityvayut formu gravimpul'sa. Sravnenie rezul'tatov raschetov s dannymi o budushih "otlovlennyh" vspleskah gravizlucheniya pozvolit dat' vazhnye ogranicheniya na uravnenie sostoyaniya neitronnyh zvezd.


    miniobzor arxiv:0712.2588 Sovremennye voprosy astroseismologii (Current Issues in Asteroseismology)
    Authors: Michael Bazot, Mario J. P. F. G. Monteiro, Christian W. Straka
    Comments: 9 pages, 2 figures - to appear in Helioseismology, Asteroseismology and MHD Connections, (Eds) L. Gizon et al., Journal of Physics Conference Series, 2008

    Nebol'shoi, no ochen' ponyatnyi obzor po astroseismologii, nachinayushiisya "s azov". Takzhe opisany osnovnye sputniki, postavlyayushie (ili eshe planiruemye) informaciyu dlya astroseismologov.


    arxiv:0712.2720 Rentgenovskoe naselenie Magellanovyh oblakov (X-ray source populations in the Magellanic Clouds)
    Authors: F. Haberl, W. Pietsch
    Comments:

    Avtory summiruyut nashi znaniya o rentgenovskih istochnikah, nablyudaemyh v Bol'shom i Malom Magellanovyh Oblakah. Seichas, blagodarya rabote Chandry i HMM-N'yuton, schet idet na sotni. Osnovnoi upor avtory delayut na svoi rezul'taty po nablyudeniyam Malogo Oblaka na HMM-N'yuton.


    arxiv:0712.2820 Temp proizvodstva i zanyatost' astronomov s Ph.D. (The Production Rate and Employment of Ph.D. Astronomers)
    Authors: Travis S. Metcalfe
    Comments: 5 pages, 4 figures, 2 tables, PASP

    Ochen' interesnaya, na moi vzglyad, zametka. Avtor proanaliziroval dinamiku kolichestva zashishayushih dissertacii po astronomii v SShA za 36 let, a takzhe trudoustroistvo zashishennyh. Interesnyi pokazatel': do polucheniya postoyannoi pozicii molodoi astronom dolzhen v srednem smenit' tri rabochih mesta.

    Authors: The Pierre auger Collaboration
    Comments: 33 pages, 8 figures, submitted to Astropart. phys

    obzor arxiv:0712.2850 Rasshirenie i uluchshenie poiska obitaemyh mirov (Expanding and Improving the Search for Habitable Worlds)
    Authors: Avi M. Mandell
    Comments: 15 pages, invited review talk, to appear in the ASP conference proceedings of the "Frank N. Bash Symposium 2007: New Horizons in Astronomy", editors: A. Frebel, J. Maund, J. Shen, M. Siegel

    "Rasshirit' i uglubit'".

    Tolkovyi obzor po vozmozhnostyam sushestvovaniya zhizni vo vselennoi i po ee poisku. Vse voprosy obsuzhdayutsya, nachinaya s tel solnechnoi sistemy. Razumeetsya, avtoru prihoditsya davat' opisanie nashih znanii ob ekzoplanetnyh sistemah, ob ih obrazovanii. Eto dovol'no uzkoe mesto, poskol'ku izvestno poka malo (osobenno pro obrazovanie). Tem ne menee, obzor chitaetsya legko i soderzhit udobnuyu svodku poslednih dannyh.


    obzor arxiv:0712.2865 Novye rubezhi v kosmologii i obrazovanii galaktik: budushie zadachi (New Frontiers in Cosmology and Galaxy Formation: Challenges for the Future)
    Authors: Richard Ellis, Joseph Silk
    Comments: 29 pages, To appear in "Structure Formation in the Universe", ed. Chabrier, G., Cambridge University Press.

    Bol'shoi, dostupnyi i tolkovyi obzor ot dvuh vedushih specialistov po vnegalakticheskoi astronomii i kosmologii. Osnovnye temy: temnaya materiya i energiya, a takzhe obrazovanie galaktik i epoha reionizacii. Horosho summirovano sovremennoe sostoyanie del. Nu a glavnoi temoi yavlyaetsya popytka analiza togo, chto nado sdelat' v blizhaishem budushem, kakimi metodami i tp.


    arxiv:0712.2877 Rentgenovskaya, IK i submillimetrovaya vspyshka Sagittarius A* (An X-ray, IR, and Submillimeter Flare of Sagittarius A*)
    Authors: D. P. Marrone et al.
    Comments: Submitted to ApJ. Comments welcome

    Kak izvestno, v centre nashei galaktiki nahoditsya sverhmassivnaya chernaya dyra (s massoi neskol'ko millionov solnechnyh). Kak izvestno, dyra nasha ves'ma neaktivna: ee svetimost' mala v sravnenii s eddingtonovskim predelom dlya takoi massy. Kak izvestno, s nei svyazan istochnik Sagittarius A*. Kak izvestno, etot istochnik vspyhivaet. Kak izvestno, prichina vspyshek neizvestna.

    Avtoram udalos' otnablyudat' odnu iz vspyshek srazu v chetyreh diapazonah s pomosh'yu pervoklassnyh instrumentov. Mozhno nadeyat'sya, chto eti dannye taki pomogut teoretikam postroit' okonchatel'nuyu model' vspyshek.

    Sm. takzhe arxiv:0712.2882, gde "konkuriruyushaya firma" obsuzhdaet tu zhe vspyshku. Etoi gruppe udalos' otnablyudat' ee i na VLA.

    Comments: 52 pages, To appear in the proceedings of the XIX Canary Island Winter School "The Cosmic Microwave Background: from Quantum fluctuations to the present Universe"

    V samam dele, nikakogo bla-bla-bla. Prakticheskoe rukovodstvo. Dazhe zadachi est'. Navernoe, budet polezno ne tol'ko tem, kto nachinaet izuchat' obrabotku kosmologicheskih dannyh, a voobshe vsem, kto nachinaet ispol'zovat' statmetody dlya raboty s dannymi.
