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).

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.

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.

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.

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.

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.
