Poyasnenie:
Chto yavlyaetsya prichinoi zagadochnyh
gamma-vspleskov?
Na etom
izobrazhenii nichem drugim ne primechatel'nogo polya v sozvezdii
Chashi,
poluchennom Kosmicheskim teleskopom Habbla, otmecheno
oslabevayushee poslesvechenie gamma-vspleska, vpervye
obnaruzhennogo
sputnikom Beppo-SAX 11 dekabrya 2001 g.
Galaktika, v kotoroi proizoshla vspyshka -
eto slaboe pyatnyshko, protyanuvsheesya vyshe i levee mesta poslesvecheniya,
nahodyasheesya na rasstoyanii neskol'kih milliardov svetovyh let.
Posle togo, kak orbital'noi
observatorii XMM-Newton
udalos' bystro zaregistrirovat'
slabeyushee
rentgenovskoe izluchenie vspleska,
astronomy
soobshili
ob obnaruzhenii
priznakov prisutstviya
himicheskih elementov
magniya, kremniya, sery, argona i kal'ciya. Veshestvo s takim sostavom
mozhet nahodit'sya v
rasshiryayushemsya oblake,
voznikshem posle vzryva massivnoi zvezdy.
Etot interesnyi
rezul'tat
mozhet svidetel'stvovat' o tom, chto sam gamma-vsplesk byl svyazan
s chrezvychaino moshnym
vzryvom
sverhnovoi, kotoryi mog proizoiti na neskol'ko dnei ran'she
moshnogo vspleska gamma-izlucheniya.
