Poyasnenie:
Na segodnyashnei kartinke predstavlena
infrakrasnaya karta
central'noi oblasti Galaktiki, na kotoroi otmecheno polozhenie
kandidatov v
magnetary -
veroyatno samyh sil'nyh
magnitov v Galaktike.
Eti kosmicheskie elektrostancii,
klassificirovannye nablyudatelyami kak Myagkie Povtornye Gamma-vspleski
(SGR) i Anomal'nye Rentgenovskie Pul'sary
(AXP), veroyatno yavlyayutsya vrashayushimisya
neitronnymi zvezdami s ochen' sil'nym magnitnym polem
razmerami
s gorod.
Naskol'ko veliko magnitnoe pole magnetara?
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 1,000,000,000,000,000 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.
V 1998 godu, s rasstoyaniya v 20 tysyach svetovyh
let ot Zemli magnetar
SGR 1900+14
nedavno proizvel moshnuyu vspyshku
gamma-izlucheniya, kotoraya byla zaregistrirovana mnogimi kosmicheskimi
apparatami.
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.
