Poyasnenie: Kak Vy nazovete neitronnuyu zvezdu s ochen' sil'nym magnitnym polem? Magnetar . Predstav'te sebe zvezdu s massoi bol'she, chem massa Solnca, s plotnost'yu neitrona i magnitnym polem, prevyshayushim zemnoe v tysyachu trillionov raz (1 i 15 nulei). Eto kazhetsya ekzoticheskim i ochen' teoreticheskim . Odnako sil'noe svidetel'stvo sushestvovaniya magnetarov osnovano na nablyudeniyah orbital'nyh rentgenovskih i gamma-observatorii . Neitronnye zvezdy obrazuyutsya v rezul'tate razrushitel'nyh vzryvov zvezd. Nekotorye stanovyatsya pul'sarami , obladayushimi otnositel'no slabym magnitnym polem. Oni vrashayutsya i ispuskayut impul'sy elektromagnitnogo izlucheniya , v rezul'tate chego ih vrashenie zamedlyaetsya. Astronomy polagayut, chto nekotorye neitronnye zvezdy stanovyatsya magnetarami s ochen' sil'nym magnitnym polem. Magnitnoe pole etih ob'ektov nastol'ko sil'noe, chto tverdaya kora neitronnoi zvezdy izgibaetsya i smeshaetsya. V rezul'tate proishodyashih zvezdotryasenii generiruyutsya korotkie vspyshki zhestkogo rentgenovskogo izlucheniya i myagkogo gamma-izlucheniya. Eto tak nazyvaemye "myagkie gamma-repitery" (ne putaite s gamma-vspleskami ). Na etom kadre iz fil'ma o vrashayushemsya izluchayushem magnetare pokazano petleobraznoe magnitnoe pole na goryachei v rentgenovskih luchah poverhnosti neitronnoi zvezdy.
