Ostatki sverhnovyh


obzor! astro-ph/0208346 Galactic SNR candidates in the ROSAT all-sky survey
Authors: Daniel Schaudel et al.
Comments: 4 pages, 1 figures, appears in "Neutron Stars in Supernova Remnants" (ASP Conference Proceedings), eds P. O. Slane and B. M. Gaensler, 200

Daetsya korotkii obzor nablyudenii ostatkov sverhnovyh na sputnike ROSAT. Osoboe vnimanie udelyaetsya poisku novyh ostatkov po rentgenovskim dannym (poka osnovnaya dolya ostatkov otkryta po radionablyudeniyam). Vydeleno 14 kandidatov, issledovaniya kotoryh prodolzhayutsya.

Dva obzora, posvyashennye nablyudeniyam ostatkov sverhnovyh. Kak ya uzhe pisal, v issledovaniyah etih ob'ektov imenno radio i rentgenovskie nablyudeniya naibolee polno dopolnyayut drug druga. BOl'shaya chast' ostatkov otkryvaetsya v radio, no seichas nachinayut otkryvat' ostatki i v rentgene. Na segodnyashnii den' izvestno 230 ostatkov (plyus kandidaty) v radiodiapazone. V rentgenovskom nablyudaetsya. Obzory interesno chitat' imenno vmeste (vozmozhno s dopolneniem o neitronnyh zvezdah v ostatkah, sm. vyshe).


obzor astro-ph/0209565 Supernova remnants and gamma-ray sources
Authors: Diego F. Torres, Gustavo E. Romero, Thomas M. Dame, Jorge A. Combi, Yousaf M. Butt
Comments: 82 pages + 23 JPEG figures

Obychno govoryat o vzaimosvyazi gamma-vspleskov so vzryvami sverhnovyh. Zdes' rech' idet o drugom. V kataloge gamma-istochnikov pribora EGRET bol'shaya chast' yavlyaetsya neotozhdestvlennoi. Eto mogut byt' vnegalakticheskie istochniki, neitronnye zvezdy, chernye dyry. Vozmozhno, eti istochniki svyazany s ostatkami sverhnovyh. O poslednei gipoteze i idet rech' v obzore.

Avtory obsuzhdayut rol' uskoreniya chastic kosmicheskih luchei v ostatkah sverhnovyh. Otmechu, odnako, chto nalichie korrelyacii s ostatkami sverhnovyh v chastnosti mozhet oznachat' svyaz' neotozhdestvlennyh istochnikov s molodymi neitronnymi zvezdami i chernymi dyrami, kotorye poyavilis' posle vzryvov, porodivshih i ostatki.


astro-ph/0210408 Otkrytie razreshennogo ostatka sverhnovoi v M31 s borta Chandra (The Discovery of a Spatially-Resolved Supernova Remnant in M31 with Chandra)
Authors: A.K.H. Kong, M.R. Garcia, F.A. Primini and S.S. Murray (CfA)
Commets: 5 pages, 3 figures; accepted for publication in ApJL

V hode nablyudenii Chandra Tumannosti Andromedy (M31) byl obnaruzhen pervyi ostatok sverhnovoi, strukturu kotorogo udalos' razreshit'. Ostatok, oboznachaemyi CXOM31 J004327.7+411829, imeet slegka vytyanutuyu kol'ceobraznuyu formu s diametrom primerno 11" (42 pk). Drugie parametry ostatka - poluchennye cherez analiz rentgenovskogo spektra -- sleduyushie: svetimost' v diapazone 0.3-7 keV mezhdu 3.2x1036 erg/s i 4.5x1037 erg/s, vozrast - ot 3200 do 22000 let, plotnost' okruzhayushego gaza dostatochno nizkaya -- 0.003-0.3 cm-3. Kak vsegda u Chandry - krasivye kartinki.


miniobzor astro-ph/0212353 Issledovaniya neteplovogo izlucheniya ostatkov sverhnovyh i pul'sarnyh tumannostei na sputnike Chandra (Chandra Studies of Nonthermal Emission from Supernova Remnants and Pulsar Wind Nebulae)
Authors: Patrick Slane
Commets: 12 pages, Invited paper in Proceedings "The Universe viewed in Gamma-rays", eds. Enomoto, Mori, and Yanagita, Universal Academy Press, in press

Na Tehasskom simpoziume dovol'no aktivno obsuzhdalis' nablyudeniya i teoriya pul'sarnyh tumannostei, osobenno dzhetov. V dannom obzore avtor rassmatrivaet dannye Chandry po ostatkam sverhnovyh i pul'sarnym tumannostyam. K sozhaleniyu, samye svezhie dannye po vneshnemu dzhetu u pul'sara v Parusah eshe ne uspeli popast' v obzor. No tem ne menee rezul'taty, privodimye v stat'e, ochen' interesny.


astro-ph/0212541 Neitronnye zvezdy v ostatkah sverhnovyh i snaruzhi (Neutron Stars in Supernova Remnants and Beyond)
Authors: V.V.Gvaramadze
Commets: 4 pages, to appear in High Energy Processes and Phenomena in Astrophysics, Proceedings of IAU Symposium #214, held 5-10 August 2002 in Suzhou, China. Edited by Xiangdong Li and Virginia Trimble

Neitronnye zvezdy obrazuyutsya posle vzryvov sverhnovyh. No pochemu-to v ostatkah my vidim ne tak uzh mnogo radiopul'sarov. Vozmozhno, prosto daleko ne vse neitronnye zvezdy v svoei molodosti prohodyat cherez etu stadiyu. No est' eshe odna vozmozhnost'. Prosto my hotim naiti pul'sar v centre ostatka, inache my govorim, chto trebuetsya slishkom bol'shaya skorost', chtoby ob'yasnit' bol'shoe smeshenie neitronnoi zvezdy ot centra ostatka, i schitaem associaciyu rezul'tatom sluchainoi proekcii radiopul'sara na ostatok sverhnovoi. V etoi korotkoi zametke avtor summiruet rezul'taty issledovanii, kotorye pytayutsya uchest', chto iznachal'no neitronnaya zvezda mozhet byt' ne v centre ostatka. Priyaina ochen' prosta. Poka massivnyaya zvezda eshe zhivet, ona proizvodit moshnyi zvezdnyi veter, vyduvaya polost', no pri etom ona eshe i dvizhetsya. Poetomu vzryv mozhet proizoiti vnutri dovol'no slozhnoi struktury, prichem ne v ee centre.



astro-ph/0303110 Neobychnyi ostatok sverhnovoi vokrug ul'tramoshnogo rentgenovskogo istochnika IC 342 X-1 (The unusual supernova remnant surrounding the ultraluminous X-ray source IC 342 X-1)
Authors: T.P. Roberts et al.
Commets: 6 pages, 3 figures (3rd in colour), accepted for publication in MNRAS

My uzhe neodnokratno pisali ob ul'tramoshnyh istochnikah, i obzory mozhno naiti v Arhive (ssylki v nashei baze obzorov). Istochnik IC 342 X-1 yavlyaetsya otnositel'no blizkim (rasstoyanie do galaktiki, v kotoroi on nahoditsya, ocenivaetsya v 4 Mpk, odnako tut est' neopredelennost'). V stat'e rech' idet ob otkrytii obrazovaniya, ochen' pohozhego na ostatok sverhnovoi, okruzhayushii ul'tramoshnyi istochnik. Radius ostatka .... 110 pk! Razumeetsya sleduet razumnoe rassuzhdenie ob obrazovanii chernoi dyry pri vzryve gipernovoi.
