A legt\u00f6bb csillag hal\u00e1la t\u00f6bb milli\u00f3 \u00e9vig tart. Amikor egy olyan csillag, mint a Nap, teljes hidrog\u00e9nk\u00e9szlet\u00e9t el\u00e9gette, kit\u00e1gul, \u00e9s v\u00f6r\u00f6s \u00f3ri\u00e1ss\u00e1 v\u00e1lik. \u00c1tm\u00e9r\u0151je ak\u00e1r t\u00f6bb milli\u00f3 kilom\u00e9ter is lehet \u2013 ez el\u00e9g nagy ahhoz, hogy elnyelje a Merk\u00far \u00e9s a V\u00e9nusz bolyg\u00f3kat.<\/p>\n<\/div>\n

Miut\u00e1n a csillag kil\u00f6kte k\u00fcls\u0151 r\u00e9tegeit, \u00f6sszeomlik, \u00e9s egy rendk\u00edv\u00fcl s\u0171r\u0171 feh\u00e9r t\u00f6rpe keletkezik. Egy te\u00e1skan\u00e1lnyi anyag a feh\u00e9r t\u00f6rp\u00e9b\u0151l ak\u00e1r 100 tonn\u00e1t is nyomhat. T\u00f6bb milli\u00e1rd \u00e9v alatt a feh\u00e9r t\u00f6rpe leh\u0171l, \u00e9s l\u00e1thatatlann\u00e1 v\u00e1lik.<\/p>\n

A Nap t\u00f6meg\u00e9nek nyolcszoros\u00e1t meghalad\u00f3 t\u00f6meg\u0171 csillagok \u00e9lete nagyon hirtelen v\u00e9get \u00e9r. Amikor elfogy az \u00fczemanyaguk, v\u00f6r\u00f6s szuper\u00f3ri\u00e1sokk\u00e1 duzzadnak. K\u00fcl\u00f6nb\u00f6z\u0151 \u00fczemanyagok el\u00e9get\u00e9s\u00e9vel pr\u00f3b\u00e1lnak \u00e9letben maradni, de ez csak n\u00e9h\u00e1ny milli\u00f3 \u00e9vig m\u0171k\u00f6dik. Ezut\u00e1n hatalmas szupern\u00f3va-robban\u00e1sban sz\u00e9trobbannak.<\/p>\n

K\u00f6r\u00fclbel\u00fcl egy h\u00e9tig a szupern\u00f3va f\u00e9nyess\u00e9ge meghaladja a galaxis\u00e1ban tal\u00e1lhat\u00f3 \u00f6sszes t\u00f6bbi csillag\u00e9t. Ezut\u00e1n gyorsan elhalv\u00e1nyul. Csak egy apr\u00f3, s\u0171r\u0171 \u00e9gitest marad bel\u0151le \u2013 egy neutroncsillag vagy egy fekete lyuk \u2013, amelyet egy t\u00e1gul\u00f3, rendk\u00edv\u00fcl forr\u00f3 g\u00e1zfelh\u0151 vesz k\u00f6r\u00fcl.<\/p>\n

A szuper\u00f3ri\u00e1s belsej\u00e9ben keletkezett elemek (p\u00e9ld\u00e1ul az oxig\u00e9n, a sz\u00e9n \u00e9s a vas) sz\u00e9tsz\u00f3r\u00f3dnak az \u0171rben. Ez a csillagpor v\u00e9g\u00fcl m\u00e1s csillagok \u00e9s bolyg\u00f3k kialakul\u00e1s\u00e1hoz vezet.<\/p>","protected":false},"excerpt":{"rendered":"
