Poyasnenie:
Svechenie, kotoroe vy vidite na etom
kombinirovannom snimke, ob'yasnyaetsya izlucheniem
"oskolkov", ostavshihsya ot vspyshki sverhnovoi. Vspyshka proizoshla v sosednei
galaktike,
Bol'shom Magellanovom Oblake, i zaregistrirovana
v kataloge pod nomerom
N49. Pri sozdanii izobrazheniya ispol'zovany dannye kosmicheskogo teleskopa
im.Habbla. Volokna gaza,
razmer
kotoryh dostigaet 30 svetovyh let,
svetyatsya v rezul'tate rasprostraneniya udarnoi volny.
Svet vzorvavsheisya zvezdy doshel do Zemli neskol'ko tysyach let nazad. Krome togo,
N49 yavlyaetsya mestom lokalizacii eshe odnogo moshnogo vzryva
- chrezvychaino intensivnoi vspyshki gamma-izlucheniya, zaregistrirovannoi
so sputnikov
5 marta
1979 goda.
Eta data yavilas' nachalom
novoi epohi v astrofizike, kogda nachalos'
issledovanie novogo ekzoticheskogo klassa zvezd.
Vinovnikom "sobytiya 5-go marta" schitaetsya
magnetar
- sil'no zamagnichennaya vrashayushayasya neitronnaya zvezda, kotoraya obrazovalas'
vo vremya vspyshki sverhnovoi, davshei ostatok
N49.
Magnetar mchitsya
skvoz'
oblako, ostavsheesya ot vzryva
sverhnovoi, so skorost'yu 1200 km/c.
