Gliese 436b – Fizik Kurallar\u0131na Uymayan Gezegen<\/h2>\n\n\n\n

Genellikle buz denince akl\u0131m\u0131za donmu\u015f bir k\u00fcp gelir. Peki ya buz neredeyse 537 santigrat derece olsayd\u0131?

Gliese 436 b, D\u00fcnya’dan yakla\u015f\u0131k 33 \u0131\u015f\u0131k y\u0131l\u0131 uzakl\u0131kta, bilinen en yak\u0131n \u00f6tegezegenlerden biridir. Bu \u00f6tegezegen yakla\u015f\u0131k Nept\u00fcn b\u00fcy\u00fckl\u00fc\u011f\u00fcnde ve kendi y\u0131ld\u0131z\u0131 olan Gliese 436’dan sadece 2,5 milyon mil uzakta. Referans olarak, Merk\u00fcr’\u00fcn G\u00fcne\u015f’ten uzakl\u0131\u011f\u0131 35 milyon mil gibi \u015fa\u015f\u0131rt\u0131c\u0131 bir mesafedir. <\/p>\n\n\n\n

Gliese 436 b’nin bile\u015fiminin b\u00fcy\u00fck bir k\u0131sm\u0131 bilinmemektedir, ancak bilim insanlar\u0131 \u00e7o\u011funlukla hidrojenden olu\u015fan bir atmosfere sahip b\u00fcy\u00fck miktarda su ile \u00e7evrili D\u00fcnya benzeri bir \u00e7ekirdek ke\u015ffetmi\u015flerdir.<\/p>\n\n\n\n

Esasen, Gliese 436 b bir y\u0131ld\u0131z\u0131n hemen yan\u0131nda konumlanm\u0131\u015f devasa bir gezegendir. Tipik olarak, d\u0131\u015f gezegen bir y\u0131ld\u0131za \u00e7ok yak\u0131n oldu\u011fu i\u00e7in atmosferin \u00e7\u00f6z\u00fclece\u011fi ve herhangi bir suyun uzaya buharla\u015faca\u011f\u0131 d\u00fc\u015f\u00fcn\u00fclebilir.  Merk\u00fcr gibi daha k\u00fc\u00e7\u00fck gezegenlerde bu do\u011frudur.  Ancak, Gliese 436 b Nept\u00fcn b\u00fcy\u00fckl\u00fc\u011f\u00fcndedir, bu nedenle \u00e7ekim alan\u0131 o kadar b\u00fcy\u00fckt\u00fcr ki sadece bir atmosferi korumakla kalmaz, ayn\u0131 zamanda y\u00fczeyindeki suyu kat\u0131 bir duruma s\u0131k\u0131\u015ft\u0131r\u0131r.  Bu da suyun buz benzeri bir halde kalmas\u0131na ve ayn\u0131 zamanda ana y\u0131ld\u0131z olan Gliese 436’ya yak\u0131nl\u0131\u011f\u0131ndan dolay\u0131 a\u015f\u0131r\u0131 s\u0131cakl\u0131klara ula\u015fmas\u0131na neden olur. Ancak Gliese 436 b’nin y\u00fczeyindeki buz normal buz de\u011fildir.  S\u0131cakl\u0131k nedeniyle kat\u0131 hale ge\u00e7en D\u00fcnya’daki buzun aksine, Gliese 436 b’deki buz sadece bas\u0131n\u00e7 nedeniyle kat\u0131 haldedir. Sonu\u00e7ta, gezegenin y\u00fczeyi 537 santigrat dereceye yak\u0131nd\u0131r. Her ne kadar \u00e7\u0131lg\u0131nca g\u00f6r\u00fcnse de bu durum, suyun yeterli bas\u0131nca maruz kalmas\u0131 halinde, D\u00fcnya’da var olmayan tamamen yeni bir forma b\u00fcr\u00fcnebilece\u011fini g\u00f6stermektedir.<\/p>\n\n\n\n
