Poyasnenie:
Po kakoi prichine obrazovalis' eti ogromnye obolochki? Po nekotorym ocenkam, eti struktury -
sledstvie vzryvov, namnogo bolee moshnyh, chem horosho izvestnye sverhnovye.
Ih nazyvali <gipernovymi
- schitaetsya, chto eto rezul'tat vzryva sverhmassivnyh zvezd, vo
vremya kotorogo vydelilos' energii na poryadok bol'she, chem pri vzryve tipichnoi
sverhnovoi.
Uchenye hotyat ob'yasnit' pri pomoshi gipernovyh
yavlenie gamma-vspleskov.
Poisk obolochek gipernovyh privel k
obnaruzheniyu dvuh kandidatov ostatkov vzryvov
gipernovyh - gromadnye rasshiryayushiesya puzyri v sosednei galaktike M101.
NGC 5471B (verhnyaya) i MF83 (nizhnyaya) byli naideny po neobychno moshnomu
rentgenovskomu izlucheniyu.
MF83 yavlyaetsya samoi krupnoi nablyudaemoi rasshiryayusheisya
obolochkoi. V nastoyashee vremya prodolzhayutsya issledovaniya proishozhdeniya i vozmozhnosti
obnaruzheniya gipernovyh i gazovyh obolochek, kotorye ostayutsya posle nih.
