Poyasnenie:
V dekabre proshlogo goda solnechnoi sistemy
dostigla plotnaya volna napravlennogo
gamma-izlucheniya. Razmery puchka byli vsego
v neskol'ko raz bol'she Zemli.
Izluchenie bylo zaregistrirovano sputnikami,
nablyudalos' zametnoe
otrazhenie ot Luny.
Istochnikom etoi vspyshki byl
magnitar vblizi
centra Galaktiki
SGR (Soft Gamma Repeater) 1806-20. On ispuskaet
redkie neperiodicheskie vspyshki myagkogo gamma-izlucheniya,
i dekabr'skaya vspyshka byla
samoi
sil'noi, iz kogda-libo zaregistrirovannyh.
Po yarkosti i maloi prodolzhitel'nosti glavnogo pika
vspyshka byla
pohozha
na nablyudaemuyu izdaleka korotkuyu vspyshku
gamma-izlucheniya (GRB).
Po mneniyu mnogih,
korotkie GRB
sushestvenno otlichayutsya ot svoih "kuzenov", dlitel'nyh vspyshek GRB,
kotorye, po-vidimomu,
svyazany s dalekimi
Sverhnovymi.
Na illyustracii pokazana seriya risunkov, izobrazhayushih
vzryvnoi process v nachal'noi stadii SGR.
Na risunkah bystro dvizhushayasya volna izlucheniya
udalyaetsya ot central'nogo
magnitara.
Vozmozhno, svyaz' mezhdu
SGR i GRB stanet bolee yavnoi
s nakopleniem nablyudenii s ispol'zovaniem
sputnika
Svift.
