Obzory preprintov astro-ph Vypusk N197 astro-ph za 13 - 19 oktyabrya 2008 goda: izbrannye stat'i Referaty otdel'nyh statei arxiv:0810.1780 Novye zavisimosti period-svetimost' i period-cvet dlya klassicheskii cefeid: III. Cefeidy malogo Magellanova Oblaka (New period-luminosity and period-color relations of classical cepheids: III. Cepheids of SMC) Authors: A. Sandage, G.A. Tammann, B. Reindl Comments: 9 pages, 10 figures, accepted for publication in A&A Avtory analiziruyut dannye po cefeidam Malogo Magellanova oblaka, kotoroe po svoei metallichnosti otlichaetsya ot nashei Galaktiki i Bol'shogo Oblaka. Pokazano, chto zavisimosti period-svetimost' i period-cvet vedut sebya ne tak kak v Mlechnom puti i BMO. Avtory eshe raz ukazyvayut na to, chto nadezhdy poluchit' kakuyu-to edinuyu zavisimost' yavlyayutsya illyuziei, t.k. nado uchityvat' metallichnost', i utverzhdayut, chto chastichno 15-procentnoe otlichie ih (dlinnoi) shkaly ot poluchennoi v rezul'tate HST Key project svyazano kak raz s etim. arxiv:0810.1959 Astrofizika kollapsov yader zvezd s pyatimegatonnym neitrinnym detektorom (Core-collapse astrophysics with a five-megaton neutrino detector) Authors: Matthey D. Kistler et al. Comments: 7 pages, 4 figures Opisyvayutsya preimushestva proekta podzemnogo vodnogo cherenkovskogo detektora Deep-TITAND, prednaznachennogo dlya poiska neitrino dostatochnoi vysokoi energii (~15 MeV) ot vzryvov sverhnovyh. Dlya sravneniya, Super-Kamiokande imel vsego 32 kilotonny vody. Proekt Giper-Kamiokande predpolagaet 0.5 megatonn vody. Pervyi mog videt' neitrino ot kollapsa tol'ko v masshtabe nashei Galaktiki (uzhe M31 daet vsego poryadka odnogo sobytiya), vtoroi - smozhet dotyanut'sya vsego lish' do 1-2 Mpk, a na takom rasstoyanii kollapsy proishodyat redko. Deep-TITAND smozhet "videt'" do 3-5 Mpk. Na takom rasstoyanii sidit srazu neskol'ko galaktik s dostatochno bol'shim tempom zvezdoobrazovaniya. Ideya sostoit v tom, chtoby pozhertvovat' neitrino nizkoi energii radi razumnoi stoimosti. Poetomu detektor predlagayut stavit' ne ochen' gluboko pod zemlei, i ne ochen' plotno raspolagat' fotoumnozhiteli. Zato mozhno budet videt' primerno kollaps v god. arxiv:0810.2107 Registraciya korotkogo GRB 080913 na ul'trabol'shom krasnom smeshenii i ego vliyanie na nashe ponimanie praroditelei i mehanizmov vydeleniya energii (Detection of the ultra-high z short GRB 080913 and its implications on progenitors and energy extraction mechanisms) Authors: D. Perez-Ramirez et al. Comments: 5 pages, submitted to A&A (Letter to the Editor) Ochen' interesnyi vsplesk. Sperva on byl klassificirovan kak dlinnyi. No potom, kogda dostoverno bylo opredeleno krasnoe smeshenie 6.7, stalo yasno, chto v svoei sisteme otscheta etot vsplesk imel dlitel'nost' vsego lish' okolo sekundy, t.e. otnositsya k korotkim. Sovremennaya standartnaya kartina pokazyvaet nam korotkie vsplesi preimushestvenno na malyh krasnyh smesheniyah, i energetika u nih pomen'she. Poetomu otkrytie GRB 080913 ochen' vazhno, dlya nashego ponimaniya gamma-vpleskov. Poka est' mnogo gipotez, i diskussiya otkryta.

Walter et al. Comments: Accepted for publication in the AJ special THINGS issue Kak vidno, obzor nastol'ko aktualen, chto emu posvyashen special'nyi vypusk AJ. Avtory poluchili na VLA podrobnye karty neitral'nogo vodoroda dlya 34 blizkih galaktik. Po izvereniyam skorostei mozhno vosstanavlivat' krivye vrasheniya. Voobshe, poluchena massa informacii.

Comments: 7 pages, A&A in press Avtory predstavlyayut sbornyi katalog dannyh po blazaram, poluchennyh v raznyh diapazonah. V syazi s zapuskom GLAST-Fermi i rabotoi ryada nazemnyh gamma-ustanovok vse eto ochen' aktual'no i polezno. Sam katalog dostupen tut. arxiv:0810.2222 Komp'yuternyi ispytatel'nyi stend dlya gipotez o vnezemnoi zhizni i razume (A numerical testbed for hypothesis of extraterrestrial life and intelligence) Authors: Duncan Forgan Comments: 22 pages, 24 figures, accepted by the Int.. J. of astrobiology Lyubopytnaya stat'ya. Po suti, avtor igraet s formuloi Dreika. Programma pozvolyaet rasschityvat' mnozhestvo vsyakih raspredelenii i voroyatnostei dlya raznyh znachenii parametrov formuly.

Boyajian et al. Comments: Accepted for publication in the Astrophysical Journal Interferometr CHARA prodolzhaet izmeryat' zvezdy. Na etot raz rech' idet o chetyreh gigantah, vhodyashih v skoplenie Giady. Dlya kazhdoi zvezdy udaetsya opredelit' temperaturu i absolyutnuyu svetimost'. Nu a dal'she uzhe mozhno opredelyat' massu i tp.

Comments: 7 pages Opisyvaetsya proekt nebol'shogo sputnika, prednaznachennogo dlya izmereniya polyarizacii gamma-vspleskov v diapazone 2-500 keV. Proekt napravlen v yanvare etogo goda v NASA. Ozhidaetsya, chto za 2 goda raboty pribor dast izmereniya dlya sotni gamma-vspleskov. Prototipy detektorov uzhe uspeshno testirovalis' v ballonnyh eksperimentah, takzhe aktivno provodilos' modelirovanie ozhidaemyh rezul'tatov. Vse osnovnye tehnologii otrabotany, poetomu mozhno sdelat' nadezhnuyu nedoroguyu missiyu, kotoraya vydast ochen' vostrebovannyi rezul'tat, t.k. polyarizacionnye nablyudeniya kraine neobhodimy dlya proverok medelei raboty central'noi mashiny gamma-vspleskov.

Poskol'ku chasticy v osnovnom zaryazhennye, a v mezhgalakticheskom prostranstve est' magnitnye polya, budut voznikat' vsyakie prostye interesnye effekty, kotorye ponyatno opisany. Tak naprimer, protony s energiei men'she 5 1017 eV, ispushennye pri gamma-vspleske na rasstoyanii 100 Mpk, ne dostignut nas dazhe za Habblovskoe vremya, esli mezhgalakticheskoe magnitnoe pole poryadka nanogaussa. obzor arxiv:0810.2690 Giperakkrecionnye diski vokrug chernyh dyr (Hyper-accreting black holes) Authors: Andrei M. Beloborodov Comments: 20 pages Giperakreciya na chernye dyry mozhet realizovyvat'sya srazu posle kollapsa ili zhe posle sliyaniya dvuh kompaktnyh ob'ektov. Kak izvestno, imenno v takih sistemah, soglasno sovremennoi kartine, voznikayut gamma-vspleski. Obzor napisan ochen' ponyatno, poetomu ego mozhno smelo vsem rekomendovat'.

V dannom horoshem nebol'shom obzore s krasivymi illyustraciyami opisyvaetsya, kak gamma-luchi mogut voznikat' v oblastyah zvezdoobrazovaniya. Istochnikami mogut byt' zvezdnye vetra massivnyh zvezd, dvoinye sistemy s massivnymi zvezdami, massivnye protozvezdy. arxiv:0810.2755 Peremennost' potoka solnechnyh neitrino i ee prilozheniya k fizike Solnca i neitrino (Solar neutrno variability and its implications for solar physics and neutrino physics) Authors: P.A.
