    obzor astro-ph/0511440 Izmenyayushiesya konstanty (Varying Constants)
    Authors: John D. Barrow
    Comments: 16 pages, no figures. Talk delivered at the Royal Society Discussion Meeting on 'The Fundamental Constants of Physics, Precision Measurements and the Base Units of SI', London, Feb. 14-15 (2005) Journal-ref: Phil. Trans. Roy. Soc. A 363, 2139-2153 (2005)

    John Barrow izvesten mnogim kak soavtor monografii po antropnomu principu. V dannoi rabote on daet obzor dannyh i teorii po t.n. izmenyayushimsya konstantam. Rech' idet ob idee, vedushei svoe nachalo ot rabot Diraka, soglasno kotoroi to, chto my nazyvaem fundamental'nymi konstantami, mozhet preterpevat' izmenenie so vremenem, v hode rasshireniya (voobshe, evolyucii) Vselennoi. Poka nikakih variacii ne obnaruzheno (nesmotrya na periodicheski poyavlyayushiesya zayavleniya o takom obnaruzhenii).

    Otmechu, chto interesnaya perspektiva obnaruzheniya variacii gravitacionnoi postoyannoi po nablyudeniyam dvoinyh radiopul'sarov obsuzhdaetsya v svezhem preprinte Bisnovatogo-Kogana gr-qc/0511072.


    miniobzor astro-ph/0511458 Astronomicheskie bazy dannyh, kosmicheskaya fotometriya i analiz vremennyh ryadov: nereshennye problemy (Astronomical databases, Space photometry and time series analysis: Open questions)
    Authors: Laurent Eyer
    Comments: 13 pages, 5 figures, invited talk to appear in C.Sterken & C.Aerts (eds), Proceedings of the ENEAS-PhD School on Variable Stars. Pecs (Hungary), September 2005

    Sovremennye instrumenty pozvolyayut poluchat' kolossal'nye ob'emy dannyh. Zachastuyu problema upiraetsya v to, chto s nimi delat'.

    V nebol'shom obzore obsuzhdayutsya nereshennye problemy, voznikayushie pri rabote s bol'shimi ob'emami astronomicheskih dannyh. V pervuyu ochered' rassmatrivaetsya primer budushego sputnika GAIA.


    astro-ph/0511472 Issledovaniya vnutrennih magnitnyh polei medlenno pul'siruyushih V-zvezd s pomosh'yu g-mod (Probing the internal magnetic field of slowly pulsating B-stars through g modes)
    Authors: S.S. Hasan, J.-P. Zahn, J. Christensen-Dalsgaard
    Comments: 4 pages, 2 figures (to appear in Astronomy & Astrophysics)

    Problema opredeleniya vnutrennih magnitnyh polei zvezd - eto chrezvychaino aktual'naya zadacha. Mnogoe, kak v protekanii evolyucii, tak i v svoistvah kompaktnogo ostatka (a takzhe i vzryva sverhnovoi) zavisit ot etih polei, kotorye, yasnoe delo, ne nablyudayutsya napryamuyu.

    Avtory predlagayut ispol'zovat' dannye po kolebaniyam zvezd dlya opredeleniya polei vnutri nih. Delo v tom, chto modelirovanie pokazalo, chto chastoty nekotoryh kolebanii ochen' sil'no zavisyat ot svoistv magnitnogo polya. Konechno, dannye kosvennye, no eto luchshe chem nichego.


    obzor astro-ph/0511481 Populyacii rentgenovskih istochnikov v galaktikah (X-ray source populations in galaxies)
    Authors: G. Fabbiano
    Comments: 40 pages. This is a review submitted to Annual Review of Astronomy & Astrophysics Comments are welcome and will be considered in a revised version

    Bol'shoi obzor po rentgenovskim istochnikam, svyazannym s tesnymi dvoinymi sistemami. Stat'ya budet opublikovana v vedushem obzornom zhurnale astronomicheskogo mira, poetomu na neskol'ko let ona mozhet stat' osnovnoi ssylkoi na obshie svoistva rentgenovskih dvoinyh.


    astro-ph/0511486 Slabeishie akkretory (The faintest accretors)
    Authors: Andrew King, Rudy Wijnands
    Comments: Andrew King, Rudy Wijnands

    Prodolzhaem temu rentgenovskih dvoinyh. Poslednie dannye nablyudenii pokazali nalichie ochen' slabyh istochnikov, yavlyayushihsya rentgenovskimi dvoinymi, v kotoryh idet akkreciya. Priroda sistem neyasna. Avtory rassmatrivayut neskol'ko idei. Svyazany oni s akkreciei s ochen' malomassivnogo kompan'ona. Vozmozhno, chto takie sistemy yavlyayutsya reliktami naseleniya III, t.e. ochen' starymi sistemami, v zvezdah kotoryh malo tyazhelyh elementov.


    astro-ph/0511488 Budushee izuchenie magnitnyh polei po dannym eksperimenta Planck (Future magnetic fields studies using the Planck surveyor experiment)
    Authors: Torsten A. Ensslin, Corina Vogt, Andre Waelkens, Alexander A. Scheckochihin
    Comments: invited talk at conference on he Origin and Evolution of Cosmic Magnetism' in Bologna 2005, eds. R. Beck, G. Brunetti, L. Feretti, and B. Gaensler, to appear in Astronomische Nachrichten, 6 pages, 3 figures

    Kak izvestno, Planck - eto sputnik novogo pokoleniya, prednaznachennyi dlya issledovaniya mikrovolnovogo fona. Odnako, krome dannyh sobstvenno po reliktu, iz poluchennyh im rezul'tatov mozhno budet vytyanut' eshe mnogo interesnogo. Avtory rassmatrivayut, chto smozhet dat' Planck dlya izucheniya krupnomasshtabnyh magnitnyh polei. V pervuyu ochered' rech' idet o vnegalakticheskih magnitnyh polyah. Krome togo, i v issledovaniyah galakticheskogo magnitnogo polya mozhno ozhidat' progressa blagodarya novomu sputniku. Zapusk ozhidaetsya v uzhe sovsem nedalekom budushem.


    astro-ph/0511523 Molodoi relyativistskii dvoinoi pul'sar J1906+0746 (The young, highly relativistic binary pulsar J1906+0746)
    Authors: D. Lorimer et al.
    Comments: 19 pages, 3 figures, accepted for publication in ApJ

    Otkryt interesnyi (i, vidimo, vazhnyi) dvoinoi pul'sar. Delo v tom, chto eto, po vsei vidimosti, ocherednaya sistema, sostoyashaya iz dvuh neitronnyh zvezd (al'ternativa - sistema s OChEN' massivnym belym karlikom). Pochemu otkrytie budet ochen' vazhnym, esli eto podtverditsya?

    Vo-pervyh, eto ochen' vazhno dlya ocenki tempa sliyaniya neitronnyh zvezd. Sam otkrytyi pul'sar - eto molodoi ob'ekt. Ocenki pokazyvayut, chto sistema sol'etsya vsego lish' cherez 0.3 milliarda let. Eto podtverzhdaet vysokii temp sliyanii neitronnyh zvezd v Galaktike.

    Vo-vtoryh,(i eto interesno lichno mne) massa sistemy ocenivaetsya v 2.6-2.65 massy Solnca. Esli schitat', chto massy komponent primerno ravny, to poluchaetsya, chto neitronye zvezdy rodilis' s massami <1.4 massy Solnca. Eto uzhe vos'maya sistema, gde tochno izmereny massy obeih komponent. Vo vseh sistemah dlya zvezd, na kotorye ne bylo sushestvennoi akkrecii (t.e. oni ne mogli sushestvenno uvelichit' svoyu massu posle rozhdeniya), nachal'nye massy men'she 1.4 mass Solnca. Lichnyi interes zaklyuchaetsya v tom, chto t.o. moya ocenka spektra nachal'nyh mass neitronnyh zvezd v okrestnostyah solnca, kotoryi my ispol'zuem v populyacionno sinteze, poluchaet sushestvennoe nablyudatel'noe podtverzhdenie.


    obzor astro-ph/0511534 Pervichnyi nukleosintez: uspehi i zadachi (Primordial Nucleosynthesis: Successes And Challenges)
    Authors: Gary Steigman
    Comments: 36 pages, 14 figures, review article to appear in the International Journal of Modern Physics E

    Obzor po pervichnomu nukleosintezu. Epigrafom mozhno bylo by vzyat' slova: "Mnogoe sdelano, no mnogoe eshe predstoit".


    astro-ph/0511579 Proishozhdenie korotkih gamma-vspleskov, nesvyazannyh s tekushim zvezdoobrazovaniem (An origin for short g-ray bursts unassociated with current star formation)
    Authors: S. D. Barthelmy et al.
    Comments: 11 pages of taxt plus figures (all in 1 file). Nature Letters (accepted; publish Dec 19, 2005)

    V principe, eto lish' ocherednaya stat'ya, posvyashennaya tomu, chto noveishie dannye po korotkim gamma-vspleskam pozvolyayut svyazat' ih so sliyaniyami neitronnyh zvezd (ili neitronnoi zvezdy i chernoi dyry). Otmechu lish', chto fakt poyavleniya stat'i v Nature chetko ukazyvaet na to, chto kolichestvo (i kachestvo) argumentov perevalilo za nekotoroe kriticheskoe znachenie. Tak chto teper' eto standartnaya gipoteza o proishozhdenii korotkim vspleskov.


    obzor astro-ph/0511217 Doveryai, no proveryai: sluchai astrofizicheskih chernyh dyr (Trust but verify: The case for astrophysical black holes)
    Authors: Scott A. Hughes
    Comments: Based on invited lectures at the 2005 SLAC Summer Institute (SSI05-L006). 22 pages, 5 eps figures

    Nebol'shoi, no ochen' soderzhatel'nyi obzor po chernym dyram. Est' nekotoryi minimum formul, tak chto vovse ne tol'ko "slova, slova, slova". Rekomenduetsya tomu, kto poka formul pro chernye dyry videl malo i hotel by uglubitsya svoe znanie bez zalezaniya v debri.


    astro-ph/0511587 Tranzientnye radio vspyshki ot vrashayushihsya neitronnyh zvezd (Transient radio bursts from rotating neutron stars)
    Authors: M. A. McLaughlin et al.
    Comments: 10 pages, 4 figures. Accepted by Nature

    Nakonec-to poyavilas' stat'ya (opyat'-taki, prinyataya v Nature), posvyashennaya otkrytiyu tranzientnyh radioistochnikov. Poskol'ku ya pisal ob etom paru mesyacev nazad, to ogranichus' lish' ssylkoi na dostatochno polnoe opisanie otkrytiya: /elementy.ru/news/164793.

    Ot sebya dobavlyu eshe, chto mogut byt' raznye gipotezy o proishozhdenii istochnikov. Na osnovanii dannyh o periodah i ih proizvodnyh avtory iznachal'no obsuzhdali vozmozhnoe rodstvo s magnitarami. V final'noi versii stat'i poyavilos' uzhe i upominanie o Velikolepnoi semerke (sam ya sklonyayus' poka imenno k takomu mneniyu). V samom dele, iz vseh izvestnyh populyacii neitronnyh zvezd Velikolepnaya semerka vo-pervyh, luchshe vseh podhodit po periodam i proizvodnym, a vo-vtoryh, (i eto ochen' vazhno) ob'ekty tipa Velikolepnoi semerki dolzhny byt' ochen' mnogochislenny (my vidim poka lish' samye blizkie i molodye). T.e. eto edinstvennyi izvestnyi tip neitronnyh zvezd, kotoryi podhodit dlya ob'yasneniya radiotranzientov s tochki zreniya tempa rozhdeniya. Tem ne menee, upomyanu eshe odnu vozmozhnost', kotoraya poka ne obsuzhdalas'. Ocenka chisla radiotranzientov v Galaktike daet chislo poryadka 400 000. Eto gde-to 0.1% ot polnogo chisla neitronnyh zvezd. Siya velichina prekrasno soglasuetsya s ocenkoi chisla sverhzvukovyh propellerov, sdelannoi v nashei rabote v 2000 godu (astro-ph/9910114). Novye ocenki Beskina i Eliseevoi (astro-ph/0508442) pokazali, chto propellery mogut poyavlyat'sya i s dostatochno korotkimi periodami. T.o. ne isklyucheno, chto novyi tip istochnikov mozhet byt' svyazan i s propellerami. Periody nemnogo korotkovaty, no eto mozhet byt' svyazano s bolee slabym magnitnym polem.


    obzor astro-ph/0511595 Vvedenie v neitrinnuyu kosmologiyu (Introduction to neutrino cosmology)
    Authors: Steen Hannestad
    Comments: 18 pages, 5 figures, to appear in Erice 2005 proceedings

    S odnoi storony, seichas rol' neitrino v kosmologii ne stol' velika, kak v eto verili nekotorye uchenye let 10-20 nazad. Prichina prosta - nizkaya massa. S drugoi storony, rol' neitrino vovse ne prenebrezhimo mala! V chem zaklyuchaetsya vazhnost' neitrino v kosmologii kak raz i opisano v obzore.

    astro-ph/0511709 Kommentarii o "privyazannyh" galaktikah (Comments on the tethered galaxy problem)
    Authors: W. J. Clavering
    Comments: 6 pages

    Rassmotren ochen' interesnyi primer povedeniya ob'ekta pri kosmologicheskom rasshirenii (spasibo A. Toporenskomu za "navodku").

    Predstav'te, chto est' galaktika, imeyushaya takuyu bol'shuyu pekulyarnuyu skorost' (napravlennuyu na nas), chto ona kompensiruet kosmologicheskoe rasshirenie. T.e. galaktika kak by privyazana k nam (tethered). Kakim budet ee krasnoe smeshenie? Ili, naprimer, galaktika s nulevym krasnym smesheniem (t.e. ee krasnoe smeshenie polnost'yu skompensirovano pekulyarnoi skorost'yu) budet priblizhat'sya k nam ili udalyat'sya? Okazyvaetsya, chto tut vse ne tak prosto.

    Authors: U. Ertan, E. Gogus, M. A. Alpar
    Comments: 17 pages, 3 figures, accepted for publication in ApJ

    Avtory pytayutsya interpretirovat' dannye rentgenovskih i IK nablyudenii odnogo iz anomal'nyh rentgenovskih pul'sarov, ispol'zuya model' ostatochnogo diska. Takie struktury mogut obrazovyvat'sya iz-za obratnogo vypadaniya (fall-back) chasti veshestva, vybroshennogo pri vzryve sverhnovoi. Po slovam avtorov, im udaetsya opisat' nablyudaemye yavleniya v ramkah svoei modeli. Otmechu, odnako, chto na moi vzglyad stroit' otdel'nuyu model' dlya ARP, ignoriruya istochniki myagkih povtoryayushihsya gamma-vspleskov, vryad li produktivno. A vspleski diskom ne ob'yasnit'.

    Authors: Eduardo Bica, Charles Bonatto, Beatriz Barbuy, Sergio Ortolani
    Comments: 14 pages and 6 figures. Astronomy & Astrophysics, accepted on Nov. 28

    Izuchaya nashu Galaktiku iznutri, my stalkivaemsya so mnozhestvom trudnostei. Dazhe takaya, vrode by, prostaya velichina, kak rasstoyanie ot centra Galaktiki, izvestna ploho.

    Avtory ispol'zuyut dannye po galakticheskim sharovym skopleniyam dlya opredeleniya parametrov Mlechnogo Puti. Sredi prochih rezul'tatov imi poluchena i ocenka rasstoyaniya do centra. Ono sostavilo 7.2+/-0.3 kpk. Eto primerno na 1 kpk men'she standartnogo znacheniya, rekomendovannogo MAS. Otmechu, chto v GAISh gruppa zvezdnyh astronomov (A.S. Rastorguev i dr.) davno ratuyut za takuyu korotkuyu shkalu rasstoyanii.

    Comments: 31 pages, 4 figures, accepted for publication to the Astrophysical Journal

    Ostatok nedavnei sverhnovoi v sozvezdii Kassiopei yavlyaetsya tainstvennym obrazovaniem. Pro etu sverhnovuyu malo chto ponyatno. Krome togo, v ostatke nablyudaetsya neponyatnyi tochechnyi ob'ekt, kotoryi ni na normal'nuyu neitronnuyu zvezdu, ni na chernuyu dyru ne pohozh.

    Avtory proveli modelirovanie vzryva sverhnovoi dlya raznyh modelei dvoinyh i odinochnyh zvezd. Raschety pokazyvayut, chto svoistva ostatka naibolee horosho ob'yasnyayutsya v scenarii vzryva zvezdy s massoi 15-25 mass Solnca, kotoraya polnost'yu poteryala svoyu obolochku za schet evolyucii v tesnoi dvoinoi sisteme.

    Pozvolyu sebe vol'no perevesti nazvanie raboty. Eto kratkii otvet na stat'yu physics/0510102, avtory kotoroi razvivayut mysl' o tom, chto Sozdatel' Vselennoi mog zashifrovat' soobshenie v parametrah mikrovolnovogo fona. V otvete raz'yasnyaetsya, chto detal'naya kartina fona zavisit ot polozheniya nablyudatelya i ot vremeni. T.e. shifrovat' kakoe-to soobshenie takim strannym sposobom ne stoilo. A istinno nebesnoe poslanie, zashifrovannoe v reliktovom fone - eto informaciya o rannei Vselennoi. V obshem, interesny primer argumentirovannoi kritiki specialistami sumasshedshei idei.
