Poyasnenie:
Na segodnyashnei kartinke predstavlena infrakrasnaya karta
central'noi oblasti Galaktiki, na kotoroi otmecheno polozhenie ob'ekta SGR 1900+14
- samogo sil'nogo magnita v Galaktike.
Schitaetsya, chto SGR 1900+14 yavlyaetsya vrashayushayusheisya
neitronnoi zvezdoi s ochen' sil'nym magnitnym polem razmerami
s gorod - ili magnetar .
Naskol'ko veliko magnitnoe pole na magnetare?
Zemnoe magnitnoe pole, kotoroe zastavlyaet otklonyat'sya strelku
kompasa, sostavlyaet 1 Gauss.
Samoe sil'noe magnitnoe pole, sozdannoe v zemnyh laboratoriyah - 100 tysyach Gauss.
A magnitnoe pole magnetara ocenivaetsya v 1000000000000000 Gauss.
Magnit takoi sily, raspolozhennyi na
polovine rasstoyaniya ot Zemli do Luny, s legkost'yu sotret informaciyu s Vashei kreditnoi
kartochki i prityanet k sebe ruchku iz Vashego karmana.
Raspolozhennyi na rasstoyanii 20 tysyach svetovyh
let ot Zemli SGR 1900+14 nedavno proizvel moshnuyu vspyshki
gamma-izlucheniya, kotoraya byla zaregistrirovana mnogimi observatoriyami.
Teper'
yasno, chto eta
vspyshka
vysokoenergichnogo izlucheniya imela izmerimoe vliyanie na zemnuyu ionosferu.
Pod
deistviem moshnogo magnitnogo polya na poverhnosti
magnetara kora neitronnoi zvezdy izgibaetsya i tryasetsya, porozhdaya intensivnye
gamma-vspleski.
