Gigantskaya vspyshka na galakticheskom magnetare
Avtory i prava: Robert Mallozzi (UAH, MSFC)
Perevod: N.A.Lipunova
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.
