Magnitnyi kover na Solnce
Avtory i prava: Kosmicheskaya solnechnaya observatoriya,
Evropeiskoe kosmicheskoe agenstvo, NASA
Perevod: Kozyreva A.V.
Poyasnenie: Vy znaete, chto Solnce vysteleno magnitnym kovrom ! Vidimaya poverhnost' Solnca useyana desyatkami tysyach severnyh i yuzhnyh magnitnyh polyusov, soedinennyh petlyami linii magnitnogo polya, kotorye prostirayutsya v solnechnuyu koronu. Nedavno issledovateli sostavili kartu po dannym kosmicheskoi solnechnoi observatorii SOHO, na kotoroi ukazali bol'shoe chislo takih sgushenii magnitnyh silovyh linii. Na segodnyashnei kartinke pokazana solnechnyi landshaft, smodelirovannyi na komp'yutere. Silovye linii soedinyayut oblasti sil'nogo magnitnogo polya. Eti nebol'shie oblasti sil'nogo polya poyavlyayutsya, delyatsya, propadayut s harakternym vremenem okolo 40 chasov. Proishozhdenie ih zagadochno i ih dinamika slozhno ukladyvaetsya v sovremennye teorii vrashatel'nogo krupnomasshtabnogo solnechnogo magnitnogo polya. Mozhet byt' zdes' rabotayut kakie-to neizvestnye nam fizicheskie processy? Esli razreshit' etu problemu, to, vidimo, my smozhem razreshit' i druguyu - global'nuyu problemu : pochemu temperatura korony Solnca v sto raz vyshe temperatury solnechnoi fotosfery ! Po nablyudeniyam SOHO vidno, chto, kogda linii magnitnogo polya razryvayutsya i peresoedinyayutsya, tem samym nagrevaya plazmu solnechnoi korony.
Na kartinke vo vstavke pomesheno real'noe izobrazhenie poverhnosti Solnca.
