Obzory preprintov astro-ph Vypusk N184 astro-ph za 21 - 30 aprelya 2008 goda: izbrannye stat'i Referaty otdel'nyh statei obzor arxiv:0804.3096 Teoriya zamagnichennyh dzhetov (Theory of magnetically powered jets) Authors: H.C. Spruit Comments: 24 pages Rassmatrivayutsya astrofizicheskie dzhety i rol' magnitnogo polya v ih formirovanii, a takzhe ego vliyaniya na nablyudaemye svoistva. V chastnosti, rol' magnitnogo polya velika v "zapuske" dzheta: energiya gravitacionnogo polya perekachivaetsya v energiyu vrasheniya v osnovanii dzheta, a ta, s pomosh'yu magnitnogo polya, uzhe perehodit v kineticheskuyu energiyu strui. Sushestvenno, chto Spruitu opyat' udaetsya sochetat' strogoe izlozhenie s ponyatnym opisaniem s pomosh'yu prostyh formul. arxiv:0804.3593 Polyarnaya kak cefeida vozvrashaetsya: 4.5 goda monitoringa s Zemli i iz kosmosa (Polaris the Cepheid returns: 4.5 years of monitoring from ground and space) Authors: H. Bruntt et al. Comments: Accepted by ApJ. 8 pages. Quality of figures 1+3+7 degraded V techenie dolgogo vremeni nablyudeniya pokazyvali, chto amplituda pul'sacii Polyarnoi zvezdy umen'shalas'. Eto svyazyvali s ee evolyuciei, dvizheniem k krayu oblasti nestabil'nosti. Odnako novye nablyudeniya, predstavlyaemye v dannoi stat'e, pokazyvayut, chto pul'sacii snova priobretayut bol'shuyu amplitudu. Avtory polagayut, chto amplituda menyaetsya ciklicheskim obrazom. arxiv:0804.3838 Mnogochastotnye integrirovannye profili pul'sarov (Multi-frequency integrated profiles of pulsars) Authors: Simon Johnston, Aris Karastergiou, Dipanjan Mitra, Yashwant Gupta Comments: Accepted for publication in MNRAS. 15 pages Avtory predstavlyayut nablyudeniya 67 pul'sarov na chastotah ot 243 MGc (na teleskope GMRT v Indii) do 3.1 GGc (na teleskope Parkes v Avstralii). V stat'e privodyatsya profili dlya 34 pul'sarov s bol'shim otnosheniem signal/shum. Avtory obsuzhdayut svoistva pul'sarov s raznymi vozrastami. V chastnosti, oni polagayut, chto oblast' v magnitosfere, v kotoroi proishodit izluchenie, evolyucioniruet po mere zamedleniya tempa vrasheniya pul'sara (chem starshe, tem nizhe v magnitosfere voznikaet izluchenie). arxiv:0804.4318 Populyaciya pul'sarov s interpul'sami i prilozheniya k evolyucii diagrammy napravlennosti (The population of pulsars with interpulses and the implications for beam evolution) Authors: Patrick Weltevrede, Simon Johnston Comments: 7 pages, 2 figures, accepted for publication in MNRAS Avtory rassmatrivayut vopros ob izmenenii ugla mezhdu magnitnoi os'yu i os'yu vrasheniya u pul'sarov s tochki zreniya doli istochnikov s interimpul'som. Interimpul's voznikaet, esli ugol mezhdu osyami blizok k 90 gradusam, togda my vidim signal ot dvuh polyarnyh shapok (eshe vozmozhna situaciya, kogda osi naoborot pochti sonapravleny, a puchok pul'sarnogo izlucheniya ochen' shirok, no, davaite, vmeste s avtorami stat'i, konservativno isklyuchim takuyu vozmozhnost'). Ocenki pokazyvayut, chto okolo 5 procentov pul'sarov dolzhny davat' interimpul'sy, esli lyubye ugly mezhdu osyami ravnoveroyatny. Odnako nablyudeniya pokazyvayut, chto dolya men'she (okolo 1.8 procenta). Prichem, dlya pul'sarov s dlinnymi periodami dolya men'she, chem dlya pul'sarov s korotkimi. Avtory rassmatrivayut raznye neslozhnye modeli, kotorye mogli by eto ob'yasnit'. Po mneniyu avtorov naibolee razumnaya model' dolzhna vklyuchat' postepennoe shozhdenie osei. Esli process idet eksponencial'no, to harakternoe vremya poluchaetsya okolo 108 - 109 let. Konechno, zhizn' mozhet byt' ustroena slozhnee, chem prostye modeli. arxiv:0804.4433 SPACE: the SPectroscopic All-sky Cosmic Explorer (SPACE: the SPectroscopic All-sky Cosmic Explorer) Authors: A. Cimatti, et al. Comments: 27 pages, Experimental Astronomy, in press. SPACE - eto novyi evropeiskii proekt, poka nahodyashiisya lish' v samom nachale sozdaniya. Ideya sostoit v poluchenie ochen' bol'shogo chisla (500 millionov) IK-spektrov galaktik na z<2 na bol'shoi ploshadke (tri chetverti neba). Krome etogo, planiruetsya glubokii prokol na uzkoi ploshadke vplot' do krasnyh smeshenii, sootvetstvuyushih samym pervym galaktikam. arxiv:0804.4483 Zoopark galaktik: morfologiya po dannym vizual'nogo prosmotra galaktik v Sloanovskom cifrovom obzore neba (Galaxy Zoo : Morphologies derived from visual inspection of galaxies from the Sloan Digital Sky Survey) Authors: Chris J. Lintott et al. Comments: Submitted to MNRAS V stat'e podrobno opisany rezul'taty proekta, v ramkah kotorogo mnozhestvo nezavisimyh (v osnovnom ne professional'nyh) pol'zovatelei vizual'no inspektirovalo SDSS na predmet klassifikacii galaktik po ih morfologii. Vsego v proekte prinyalo uchastie okolo 100 000 pol'zovatelei, sdelavshih okolo 40 mln. ocenok. Razumeetsya, provodilis' testy, kogda nebol'shie vyborki galaktik prosmatrivalis' professionalami, a potom rezul'taty sravnivalis' s ocenkami neprofessioneal'nyh pol'zovatelei. Soglasie bylo horoshim. arxiv:0804.4585 Otskakivayushaya sverhmassivnaya chernaya dyra v kvazare SDSSJ092712.65+294344.0? (A recoiling supermassive black hole in the quasar SDSSJ092712.65+294344.0?) Authors: S. Komossa, H. Zhou, H. Lu Comments: To appear in ApJ Letters, 678, L81, 2008 (May 10 issue) Avtory polagayut, chto oni nashli nailuchshii primer "otskakivayushei" chernoi dyry. Chto eto takoe? Napomnyu, chto est' takoi fenomen - gravitacionno-volnovaya raketa. V rezul'tate sliyaniya dvuh dyr obrazuetsya edinyi ob'ekt, kotoryi priobretaet lineinyi impul's. Znachit, my dolzhny videt' primery dyr, vyletayushih iz yadra posle sliyaniya (razumeetsya, chashe vsego dyra ne budet kak pulya vyletat' iz galaktiki i uletat' v beskonechnost', prosto ona nachnet boltat'sya vblizi centra, t.k. ee skorost' otdachi men'she skorosti ubeganiya). V kvazare SDSSJ092712.65+294344.0 kak raz nablyudaetsya nechto pohozhee. Obsudit' v ZhZh-soobshestve ru_astroph. Obsudit' na Astroforume v Nauchnoi panorame. My budem starat'sya hotya by perechislit' interesnye (dlya shirokoi publiki) stat'i, poyavivshiesya v razdele physics (vklyuchaya cross-listing). arxiv:0804.3086 Prepodavanie sverhtekuchesti na nachal'nom urovne (Teaching superfluidity at the introductory level) Authors: Alexander J.M. Schmets, Wouter Montfrooij Comments: 7 pages Na dostupnom urovne rassmatrivaetsya sverhtekuchest' v gelii-4. arxiv:0804.3116 Raznica v impakt-faktorah v raznyh oblastyah i v raznye vremena (Differences in Impact Factor Across Fields and Over Time) Authors: Benjamin M. Althouse et al. Comments: 9 pages Kak sleduet iz nazvaniya, avtory obsuzhdayut raznicu v impakt-faktorah zhurnalov v raznyh oblastyah i v raznye periody vremeni. Chto kasaetsya poslednego, to oni obrashayut vnimanie na to, chto kraine sushestvenno, chto lyudi prosto stali bol'she ssylat'sya, t.e. spiski literatury prosto stali gorazdo dlinnee. Chto kasaetsya raznicy mezhdu oblastyami, to tut avtory ukazyvayut, chto kraine sushestvenno, chto v odnih oblastyah mnogo ssylok na literaturu, vklyuchennuyu v Thom- son Journal Citation Reports (JCR), a v drugih - malo. I eto bolee sushestvenno, chem drugie faktory. Vernut'sya k nachalu stranicy
