    astro-ph/0508629 Polnyi obzor tranzientov na radionebe i ego primeneniya k gamma-vspleskam, sverhnovym i drugim relyativistskim vzryvam (A Complete Survey of the Transient Radio Sky and Implications for Gamma-Ray Bursts, Supernovae, and other Relativistic Explosions)
    Authors: Avishay Gal-Yam et al.
    Comments: Submitted to ApJ.

    Avtory proveli poisk vspyhivayushih radioistochnikov, svyazannyh s gamma-vspleskami i sverhnovymi. Tol'ko v dvuh sluchayah byli obnaruzheny radiotranzienty. V pervom sluchae eto sverhnovaya v blizkoi galaktike NGC 4216. A vot vo vtorom sluchae - eto nechto strannoe (ni sverhnovaya, ni gamma-vsplesk). Avtory vyskazyvayut dve gipotezy: vspyshka aktivnogo yadra ili vspyshka kakogo-to galakticheskogo kompaktnogo ob'ekta.

    Avtory dayut vazhnye predely na polnoe chislo radiotranzientov na nebe i predskazyvayut, chto budushie bolee glubokie poiski dolzhny privesti k obnaruzheniyu radioistochnikov, svyazannyh s nenablyudavshimisya gamma-vspleskami.


    obzor astro-ph/0508669 Orientaciya galaktik v mestnom sverhskoplenii (Orientation of Galaxies in the Local Supercluster)
    Authors: F. X. Hu, G.X. Wu, S. Okamura
    Comments: 21 pages, 10 figures; Accepted for publication in Astrophysics and Space Science

    Privodyatsya dannye po orientacii galaktik v mestnom sverhskoplenii. Okazyvaetsya, orientirovany oni ne sluchainym obrazom. V srednem ploskosti galaktik vystraivayutsya perpendikulyarno ploskosti sverhskopleniya (effekt osobenno chetko proslezhivaetsya dlya linzovidnyh galaktik, a vot spiral'nye galaktiki, nevhodyashie v gruppy i skopleniya, pokazyvayut prakticheski izotropnoe raspredelenie). Galaktiki, vhodyashie v skoplenie v Deve, v srednem orientirovany v napravlenii na centr skopleniya.


    astro-ph/0508678 Diski i planety vokrug massivnyh belyh karlikov (Disks and Planets Around Massive White Dwarfs)
    Authors: M. Livio et al.
    Comments: 8 pages, 1 figure; accepted ApJL

    Predskazyvaetsya, chto massivnye belye karliki dolzhny imet' pylevye diski i, vozmozhno, planety, sostoyashie iz uglekisloty. Dlya obnaruzheniya takih ob'ektov neobhodimy glubokie IK nablyudeniya.


    astro-ph/0509031 Poluchaya tychki: VLBA parallaks dlya giperbystrogo pul'sara B1508+55 (Getting Its Kicks: A VLBA Parallax for the Hyperfast Pulsar B1508+55)
    Authors: S. Chatterjee et al.
    Comments: 5 pages, including 2 figures; Journal-ref: Astrophys.J. 630 (2005) L61-L64

    Izvestno, chto pul'sary (da i neitronnye zvezdy voobshe) obladayut bol'shimi prostranstvennymi skorostyami. Impul's priobretaetsya imi v moment rozhdeniya za schet asimmetrii vzryva sverhnovoi. Skorosti mozhno ocenivat' po-raznomu. Naprimer, po forme tumannosti vokrug pul'sara, ili po ego smesheniyu otnositel'no centra ostatka sverhnovoi. No hochetsya, konechno zhe, poluchat' neposredstvennye dannye. Dlya eto nuzhno izmerit' smeshenie pul'sara na nebe (eto legko sdelat') i neobhodimo opredelit' rasstoyanie do pul'sara (a vot eto sdelat' uzhe zatrudnitel'no).

    Avtory po dannym VLBA izmerili parallaks pul'sara V1508+55. V rezul'tate udalos' opredelit' skorost' etoi neitronnoi zvezdy. Poluchennoe znachenie - 1083 km/s - okazalos' rekordnym sredi poluchennyh neposredstvennym obrazom.


    astro-ph/0509046 Bystraya opticheskaya peremennost' v galaktikah: nablyudeniya korotkozhivushih vspyshechnyh sobytii (Fast Optical Photometry of Galaxies: Observations of Short-Lived Flare Events)
    Authors: B. E. Zhilyaev et al.
    Comments: 4 pages, 3 figures, proceedings of the conference "AGN Variability from X-rays to Radio Waves", Nauchny, Ukraine, June 2004, to be published in ASP Conference Series, Vol XX, 2004

    Opticheskii monitoring galaktik M85 i NGC 7331 pokazal nalichie korotkih vspyshek. Vspyshka ochen' bystro (desyatki mikrosekund) razvivaetsya, a zatem zatuhaet na vremenah poryadka 1 sekundy. Amplituda sostavlyaet ot desyatyh zvezdnoi velichiny do neskol'kih velichin. Chto vspyhivaet - neponyatno.


    astro-ph/0509068 Registraciya gigantskih impul'sov ot pul'sara PSR J1752+2359 (Detection of Giant Pulses in pulsar PSR J1752+2359)
    Authors: A. A. Ershov, A. D. Kuzmin
    Comments: 5 pages, 4 figures, 1 table. Accepted for publication in A&A

    Pushinskie radioastronomy zaregistrirovali gigantskie impul'sy ot ocherednogo pul'sara. Primerno kazhdyi 270-i impul's v 40 raz prevoshodit po intensivnosti tipichnoe znachenie. Samyi sil'nyi iz obnaruzhennyh impul'sov prevoshodil srednii v 260 raz.


    astro-ph/0509074 Demografiya dolgoperiodicheskih komet (The Demographics of Long-Period Comets)
    Authors: P. J. Francis
    Comments: Accepted for publication in Astrophysical Journal. 22pages, 14 figures

    Po dannym LINEAR (Lincoln Near-Earth Asteroid Research) postroeno raspredelenie dolgoperiodicheskih komet po rasstoyaniyu v perigelii i po absolyutnoi velichine. Osnovnoi vyvod raboty takov, chto oblako Oorta mozhet byt' sushestvenno men'she, chem ozhidalos', t.k. net sil'nogo rosta chisla komet v storonu bolee dalekih i bolee slabyh.


    astro-ph/0509108 Kommentarii ob izluchenii vysokoi energii ot vnegalakticheskih oblastei zvezdoobrazovaniya (Some comments on the high energy emission from regions of star formation beyond the galaxy)
    Authors: Diego F. Torres, Eva Domingo-Santamaria
    Comments: 17 pages, 6 figures. Solicited Brief Review prepared for Modern Physics Letters A

    Sovremennye nazemnye gamma-teleskopy (H.E.S.S., MAGIC i dr), a takzhe budushie sputniki (GLAST) mogut zaregistrirovat' izluchenie, ishodyashee ot moshnyh oblastei zvezdoobrazovaniya. V svyazi s etim avtory dayut obzor mehanizmov vozniknoveniya izlucheniya i perechislyayut ob'ekty, registraciya gamma-luchei ot kotoryh vozmozhna. Sredi poslednih osobo stoit vydelit' blizkuyu galaktiku s vspyshkoi zvezdoobrazovaniya v central'noi oblasti - NGC 253 - i bolee dalekuyu, no i bolee moshnuyu vspyshku zvezdoobrazovaniya - galaktiku Arp 220.


    obzor astro-ph/0509117 INTEGRAL tri goda spustya (INTEGRAL three years later)
    Authors: L. Foschini, G. Di Cocco, G. Malaguti
    Comments: 8 pages, no figures. Proceedings of the workshop "Science with the New Generation of High-Energy Gamma-Ray Experiments", Cividale del Friuli (Italy), 30 May - 1 June 2005. Invited talk

    Proshli tri iz shesti zaplanirovannyh let raboty sputnika INTEGRAL. Avtory kratko opisyvayu kak sam apparat (i ustanovlennoe na nem oborudovanie), tak i osnovnye rezul'taty, poluchennye za pervuyu polovinu vremeni zhizni sputnika.




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

    physics/0509048 Modificirovannyi indeks dlya ocenki individual'nogo vklada uchenogo (Modified index to quantify individual's scientific research output)
    Authors: Pablo Diniz Batista, Monica Guimaraes Campiteli, Osame Kinouchi, Alexandre Souto Martinez
    Comments: 3 pages, 4 figures and 1 table

    Avtory podmetili, chto predlozhennyi Hirshem indeks korreliruet s chislom soavtorov stat'i. Sootvetstvenno, predlagaetsya modifikaciya indeksa. Krome togo, provoditsya analiz brazil'skoi nauki otdel'no po chetyrem oblastyam znanii.
