    miniobzor astro-ph/0402324 Kosmicheskaya topologiya: kratkii obzor (Cosmic Topology: a Brief Overview)
    Authors: M.J. Reboucas, G.I. Gomero
    Comments: Revtex4, 9 pages, 2 figures. Ivited talk delivered at "XIV National Meeting of the Brazilian Physical Society, section Particles and Fields, Caxambu - MG, Brazil, from September 30 to October 04, 2003

    Vopros o topologii Vselennoi vsegda byl populyaren. V poslednee vremya nekotoraya aktivnost' nablyudalas' v svyazi s dannymi sputnika WMAP, a osobenno v svyazi s rabotoi Lyumine i dr.

    V etoi stat'e avtory dayut kratkii obzor problematiki i osnovnyh rezul'tatov. V kachestve bolee populyarnogo izlozheniya mozhno prochest' stat'yu na Astronete.


    astro-ph/0402328 Obrazovanie dvoinyh asteroidov v poyase Koipera za schet obmennyh vzaimodeistvii (The formation of Kuiper-belt Binaries through Exchange Reactions)
    Authors: Yoko Funato et al.
    Comments: 12pages, 4 figures

    Neskol'ko procentov ob'ektov v poyase Koipera yavlyayutsya dvoinymi. Oni obladayut sleduyushimi svoistvami:
    massy kompan'onov dvoinoi primerno ravny,
    orbity dvoinyh sil'no ekscentrichny,
    orbity shirokie (v 100 i bolee raz prevoshodyat radius kompan'onov).

    Sushestvuyut problemy s ob'yasneniem etih svoistv, poskol'ku pri neposredstvennom obrazovanii dvoinyh asteroidov dolzhny byli voznikat' gorazdo bolee tesnye sistemy s pochti krugovymi orbitami. Avtory predlagayut svoyu model', v kotoroi dvoinye formiruyutsya na rannei stadii rosta transneptunovyh ob'ektov za schet gravitacionnoi neustoichivosti v pylevom protoplanetnom sloe.


    astro-ph/0402334 Modeli zvezd galo s ekstremal'no nizkoi metallichnost'yu (Models for extremely metal-poor halo stars)
    Authors: A. Weiss et al.
    Comments: submitted to Astron. Astrophys., 9 pages, 3 figures

    V galo nashei Galaktiki nablyudayutsya zvezdy s ochen' malym soderzhaniem elementov tyazhelee geliya. V etih ob'ektah nablyudaetsya nekotoroe kolichestvo ugleroda i azota, chto neobhodimo kak-to ob'yasnyat'. Sushestvuyut dve modeli. V pervoi iz nih zvezdy formiruyutsya "chistymi", a uglerod i azot narabatyvabtsya vo vremya gelievyh vspyshek v yadre. Vo vtoroi, nekotoroe kolichestvo tyazhelyh elementov iznachal'no vhodit v sostav zvezdy iz-za togo, chto protozvezdnoe veshestvo bylo obogasheno vzryvom blizkoi sverhnovoi.

    Avtory detal'no modeliruyut evolyuciyu zvezdy HE0107-5240 i prihodyat k vyvodu, chto vtoraya model' luchshe opisyvaet nablyudeniya.


    obzor astro-ph/0402335 Regulyarnye dvizheniya v sistemah ekzoplanet (Regular Motions in Extra-Solar Planetary Systems)
    Authors: S. Ferraz-Mello et al.
    Comments: 25 pages, 11 figures, to be published in "Chaotic Worlds: From Order to Disorder in Gravitational N-Body Systems" (B.A.Steves, ed.), Kluwer Acad. Publ.

    Eto obzor po dinamike planetnyh sistem v primenenii k ekzoplanetam. Stat'ya dostatochno tehnicheskaya, no vmeste s tem dostupnaya kazhdomu, kto pomnit standartnyi universitetskii (institutskii) kurs po teormehu.


    astro-ph/0402338 Vzveshivanie kaspa v Galakticheskom centre (Weighing the cusp at the Galactic Centre)
    Authors: N. Mouawad et al.
    Comments: 11 pages, 5 figures submitted to astron. and astroph

    Kak izvestno, v centre nashei Galaktiki nahoditsya chernaya dyra. Ee massa neploho izvestna: okolo 3-4 millionov mass Solnca. Eto bylo opredeleno po izmereniyam orbital'nogo dvizheniya zvezd v neposredstvennoi blizosti ot centra Galaktiki. Odnako chernaya dyra okruzhena nebol'shim zvezdnym skopleniem s bystro rastushei k centru plotnost'yu - kaspom. Massa kaspa namnogo men'she massy chernoi dyry, no vse ravno, on mozhet okazyvat' nebol'shoe vliyanie na dinamiku zvezdnyh orbit.

    Avtory detal'no issleduyut etot vopros. Osnovnoi vyvod sostoit v tom, chto massa kaspa sostavlyaet primerno 10 procentov ot massy chernoi dyry. Krome togo, oni obsuzhdayut prirodu ob'ektov, formiruyushih kasp. V chastnosti, po vsei vidimosti tam velika dolya "zvezdnyh ostatkov" - belyh karlikov, neitronnyh zvezd i chernyh dyr.


    astro-ph/0402344 Moglo li chto-to raspadat'sya, isparyat'sya ili annigilirovat' vo vremya pervichnogo nukleosinteza? (Did Something Decay, Evaporate, or Annihilate during Big Bang Nucleosynthesis?)
    Authors: Karsten Jedamzik
    Comments: 7 pages, 3 figures

    Processy tipa raspada adronov, ispareniya ili annigilyacii reliktov predydushih epoh (mikroskopicheskih pervichnyh chernyh dyr ili tyazhelyh chastic) proishodyashie vo vremya pervichnogo nukleosinteza mogut sushestvenno povliyat' na ego rezul'taty, v chastnosti na kolichestvo obrazuyushihsya izotopov litiya (6Li i 7Li). Detal'nomu rassmotreniyu takogo vliyaniya (na osnove chislennogo modelirovaniya processov sinteza) i posvyashena dannaya stat'ya.


    astro-ph/0402349 CFL zvezdy v dvoinyh sistemah: "pryachutsya" li oni sredi kandidatov v chernye dyry? (Self-bound CFL stars in binary systems : are they "hidden" among the black hole candidates?)
    Authors: J. E. Horvath, G. Lugones
    Comments: 4 pages, 3 figures

    My neodnokratno obrashali vashe vnimanie na raboty, posvyashennye probleme "identifikacii" chernyh dyr (Narayan et al.; Abramowicz et al.). Osobo hochetsya vydelit' nedavnyuyu stat'yu Ye-Fei Yuan et al.. Problema v obnaruzhenii neposredstvennogo proyavleniya gorizonta.

    Narayan et al. polagayut, chto lyuboi kompaktnyi ob'ekt s massoi bolee 3 mass solnca i bez rentgenovskih vspleskov pervogo tipa (oni svyazany s zagoraniem "termoyadernogo topliva" na poverhnosti) yavlyaetsya ochen' sil'nym kandidatom v chernye dyry. Horvat i Lugones v svoei stat'e rassmatrivayut nekotoruyu ekzoticheskuyu al'ternativu - CFL zvezdy (CFL=color flavor locked).

    CFL zvezdy eto podvid togo, chto inogda ob'edinyayut obshim terminom "neitronnye zvezdy". Na samom dele v zavisimosti ot uravneniya sostoyaniya sostav kompaktnogo ob'ekta mozhet byt' sovsem ne "neitronnym". V chastnosti, mogut sushestvovat' kvarkovye zvezdy raznyh tipov. CFL zvezdy - odin iz nih. Eti ob'ekty otlichayutsya dovol'no bol'shimi maksimal'nymi massami i otsutstviem normal'noi poverhnosti. T.o. po mneniyu avotrov oni mogut pryatat'sya sredi kandidatov v chernye dyry "po Narayanu".

    Stat'ya korotkaya i ponyatnaya. Tak chto v nei legko razobrat'sya.


    astro-ph/0402354 Astroseismologiya zvezdy nyu Eridana, peremennoi tipa beta Cefeya: interpretaciya i prilozhenie k spektru oscillyacii (Asteroseismology of the Beta Cephei star Nu Eridani: Interpretation and applications of the oscillation spectrum)
    Authors: A. A. Pamyatnykh et al.
    Comments: 8 pages, 7 figures, accepted in MNRAS

    Posle togo, kak osnovnye teoreticheskie problemy gelioseismologii byli uspeshno resheny, metody nablyudenii razrabotany i oprobovany, i finansirovanie dannogo napravleniya issledovanii sokratilos', chast' issledovatelei obnaruzhili, chto vse eti metody mozhno primenyat' i k naibolee yarkim zvezdam. Tak voznikla astroseismologiya.

    U zvezdy ν Eri, yavlyayusheisya peremennoi tipa β Cephei, nablyudaetsya samyi bogatyi spektr kolebanii.

    Spektr interpretiruetsya v terminah normal'nyh mod kolebanii zvezdy. Dannye o tom, kakie iz vozmozhnyh mod kolebanii vozbuzhdeny, a kakie net, pozvolyayut postroit' "seismicheskuyu" model' etoi zvezdy. Nablyudayusheesya rassheplenie dipol'nyh mod pozvolyaet sdelat' zaklyuchenie o skorosti vrasheniya yadra zvezdy.

    astro-ph/0402376 O sootnoshenii mezhdu massami central'noi chernoi dyry i baldzha galaktiki (On the Black Hole Mass - Bulge Mass Relation)
    Authors: Nadine Haering and Hans-Walter Rix
    Comments: 11 pages, 3 figures, accepted in ApJ Letters

    Proizvedena ocherednaya pereproverka ukazannoi zavisimosti. Avtory nashli, chto zavisimost' pochti lineinaya

    Mbh ~ Mbulge1.12+/-0.06

    Dlya baldzha s massoi Mbulge~5x1010 Mo srednyaya massa central'noi chernoi dyry sostavlyaet 0.14% +/- 0.04% ot massy baldzha.


    astro-ph/0402385 Povtornoe mikrolinzirovanie v sobytii OGLE-2003-BLG-095: mikrolinzirovanie dvoinogo istochnika (The repeating microlensing event OGLE-2003-BLG-095: A plausible case for microlensing of a binary source)
    Authors: Matthew J. Collinge (Princeton)
    Comments: 16 pages, 4 figures, 2 tables

    Kogda (s podachi Bogdana Pachin'skogo) byli nachaty pervye poiski gravitacionnogo mikrolinzirovaniya, eti sobytiya harakterizovalis' sleduyushim obrazom:

    1. monohromaticheskoe - krivaya bleska ne zavisit ot dliny volny sveta;
    2. simmetrichnaya kolokoloobraznaya krivaya bleska (dlya nee est' tochnaya formula);
    3. odnorazovost' - sobytie ne povtoryaetsya (v tom zhe meste na nebesnoi sfere).

    Pozzhe, kogda bol'shoe kolichestvo klassicheskih sobytii, udovletvoryayushih trem perechislennym kriteriyam, bylo uzhe obnaruzheno, nachali iskat' situacii, v kotoryh nekotorye iz etih uslovii mogli by narushat'sya.

    Monohromatichnost' krivoi bleska mozhet narushat'sya iz-za vliyaniya effekta potemneniya diska zvezdy k krayu ili iz-za togo, chto chast' sveta daet linza.

    Narushenie formy krivoi bleska mozhet byt' vyzvano dvoistvennost'yu linzy. Obychno v etom sluchae krivye bleska poluchayutsya ochen' slozhnymi iz-za peresecheniya kaustik. Drugaya prichina - vliyanie parallaksa - ona proyavlyaetsya tol'ko dlya samyh blizkih linz i v samyh dolgih (poryadka goda) sobytiyah mikrolinzirovaniya. Konechnyi parallaks linzy delaet krivuyu bleska slegka nesimmetrichnoi.

    Nenarushennym ostavalos' tol'ko poslednee pravilo - sobytiya ne povtoryalis'. Ono narushilos' v sobytii OGLE-2003-BLG-095.


    Krivaya bleska sobytiya OGLE-2003-BLG-095

    V etom sobytie chetko vidny dva simmetrichnyh pika, razdelennyh intervalom primerno v 100 dnei. Vozmozhny dve interpretacii podobnogo sobytiya:

    1. eto linzirovanie dvoinoi zvezdy;
    2. zvezdy odinochnaya, no linza - shirokaya dvoinaya.

    Obe modeli horosho opisyvayut nablyudeniya - zelenaya i krasnaya krivye na risunke. Razlichit' ih, po-vidimomu, ne udastsya iz-za nebol'shoi sobstvennoi peremennosti linzirovannoi zvezdy.

    Eshe odnoi neobychnoi mikrolinze OGLE-2002-BLG-055 posvyashena stat'ya astro-ph/0402417. V etom klassicheskoi po svoistvam sobytii odna tochka ochen' sushestvenno, na 0.6 zvezdnoi velichiny, podskochila vverh.


    Krivaya bleska sobytiya OGLE-2002-BLG-055

    Zdes' tozhe vozmozhny dve interpretacii: dvoinaya linza u kotoroi vtoroi komponent - planeta ili dvoinaya zvezda-istochnik slabyi komponent kotoroi okazalsya gorazdo blizhe k luchu zreniya, chem yarkii.


    astro-ph/0402392 Evolyuciya magnitnogo polya v kore neitronnyh zvezd pod deistviem effekta Holla i omicheskogo zatuhaniya (Magnetic Field Evolution in Neutron Star Crusts due to the Hall Effect and Ohmic Decay)
    Authors: Andrew Cumming et al.
    Comments: 18 pages, 13 figures, Submitted to ApJ

    Eshe odna stat'ya pro evolyuciyu magnitnogo polya u neitronnyh zvezd. Ee osobennost' - uchet effekta Holla (naryadu s drugimi effektami). Privedeny rezul'taty chislennogo modelirovaniya, pokazany vozmozhnye konfiguracii polei.

    [Effekt Holla zaklyuchaetsya v vozniknovenii v provodnike s tokom I, pomeshennom v magnitnoe pole B, elektricheskogo polya v napravlenii, perpendikulyarnom k I i B. Svyazan s otkloneniem dvizhushihsya v provodnike elektronov silami Lorenca.]


    obzor astro-ph/0402404 Dekonfaiment kvarkov i ego vliyanie na radiusy i predel'nye massy kompaktnyh zvezd (Quark deconfinement and implications for the radius and the limiting mass of compact stars)
    Authors: Ignazio Bombaci et al
    Comments: 34 pages, 10 figures

    Avtory yavlyayutsya storonnikami shiroko rasprostranennoi segodnya gipotezy, chto v kompaktnyh (neitronnyh) zvezdah vozmozhen perehod ot nuklonnogo veshestva k kvarkovoi plazme, no v otlichie ot bol'shinstva issledovatelei oni priderzhivayutsya mneniya, chto takoi perehod budet proishodit' postepenno i zvezda mozhet nadolgo zaderzhat'sya v metastabil'nom "gibridnom" perehodnom sostoyanii.

    Avtory podrobno rassmatrivayut svoi variant teorii, razlichnye ego sledstviya i, v chastnosti, ee prilozhenie k "zaderzhannym" gamma-vspleskam, kotorye proishodyat cherez nekotoroe vremya posle kollapsa massivnoi zvezdy.


    !!! astro-ph/0402418 Sil'naya shirokaya liniya poglosheniya v rentgenovskom spektre blizkoi odinochnoi neitronnoi zvezdy RX J1605.3+3249 (A Strong, Broad Absorption Feature in the X-ray Spectrum of the Nearby Neutron Star RX J1605.3+3249)
    Authors: M. H. van Kerkwijk et al.
    Comments: 30 pages, 7 figures, accepted in ApJ

    Nablyudeniya observatorii XMM-N'yuton pokazali, chto v spektre tret'ei po yarkosti odinochnoi neitronnoi zvezdy nablyudaetsya shirokaya i moshnaya absorbcionnaya osobennost' (proshe govorya, liniya poglosheniya). Centr etoi linii prihoditsya na Dlinu volny 27 angstrem ili na energiyu 0.45 keV. V stat'e podrobno opisana metodika provedeniya i obrabotki nablyudenii, no osnovnoe mozhno pocherpnut' iz privedennogo nizhe risunka.


    Srektr ob'ekta RX J1605.3+3249, sploshnoi i punktirnoi liniyami pokazany kontinuumy dvuh naibolee udachnyh ego approksimacii (bez ucheta linii poglosheniya).

    Avtory prihodyat k zaklyucheniyu, chto eto protonnaya ciklotronnaya liniya, oslablennaya kvantovymi vakuumnymi effektami. V etom sluchae magnitnoe pole na poverhnosti dolzhno bylo by sostavlyat' 7x1013 Gs (bez ucheta gravitacionnogo pokrasneniya).

    Authors: Z. Fodor, S.D. Katz, A. Ringwald, H. Tu
    Comments: 20 pages, 12 figure

    Soglasno sovremennym teoreticheskim predstavleniyam fotony s energiyami vyshe 4x1019 erg ne mogut preodolevat' kosmologicheskie rasstoyaniya iz-za vzaimodeistviya s myagkimi fotonami reliktovogo izlucheniya, i v spektre kosmicheskih luchei vyshe etoi energii dolzhen nablyudat'sya zaval (kotoryi nosit imena Greisena-Zacepina-Kuz'mina). Pohozhe, odnako, chto etot zaval ne nablyudaetsya (v dannyh raznyh observatorii est' nekotorye protivorechiya).

    Comments: 53 pages, 17 figures

    Samye sovremennye teorii elementarnyh chastic luchshe vsego opisyvayut fiziku nashego mira, kogda on yavlyaetsya desyati- ili odinnadcatimernym. My "ne vidim" dopolnitel'nye izmereniya potomu, chto oni zamknutye i kompaktnye. Odnako v poslednee vremya predpolozhenie o tom, chto protyazhennost' etih izmerenii poryadka plankovskoi dliny, stanovitsya neobyazatel'nym, odno ili dva iz kompaktnyh izmerenii mogut byt' gorazdo bol'she, vplot' do neskol'kih nanometrov.
