G\u00fcne\u015f’in en b\u00fcy\u00fck gizemlerinden biri, y\u00fczey s\u0131cakl\u0131\u011f\u0131 sadece 6000 santigrat dereceyken, atmosferinin \u00fcst k\u0131sm\u0131 olan koronan\u0131n s\u0131cakl\u0131\u011f\u0131 bir milyon dereceyi ge\u00e7mesidir.<\/p>\n
Nature dergisinde yay\u0131mlanan bu \u00e7al\u0131\u015fmada yer almayan ancak ara\u015ft\u0131rmaya ili\u015fkin a\u00e7\u0131klamalarda bulunan biliminsan\u0131 Daniel Verscharen, “Bu durum, G\u00fcne\u015f fizi\u011fi i\u00e7in olduk\u00e7a b\u00fcy\u00fck bir bilmece. Neden korona bu kadar y\u00fcksek bir s\u0131cakl\u0131\u011fa sahip?” dedi.<\/p>\n
Bu durum birka\u00e7 nedenden dolay\u0131 olduk\u00e7a \u00f6nemlidir. Bunlardan biri, G\u00fcne\u015f r\u00fczgarlar\u0131n\u0131n olu\u015fumudur. Koronadaki y\u00fcksek s\u0131cakl\u0131\u011fa sahip plazma, saatte 2 milyon kilometreyi a\u015fan h\u0131za sahip g\u00fcne\u015f r\u00fczgarlar\u0131n\u0131 olu\u015fturabilmektedir.<\/p>\n
Verscharen, Parker Solar Probe\u2019un misyonunu anlatarak, “Bu ara\u015ft\u0131rmada ama\u00e7 G\u00fcne\u015f’e bu sorular\u0131 yan\u0131tlayacak kadar yakla\u015fmakt\u0131r” a\u00e7\u0131klamalar\u0131nda bulundu.<\/p>\n

Bu mesafe, Merk\u00fcr aras\u0131ndaki mesafenin yar\u0131s\u0131ndan daha az ancak daha \u00f6nce ara\u015ft\u0131rmalar i\u00e7in kullan\u0131lan herhangi bir uzay arac\u0131n\u0131n kat etti\u011fi mesafenin iki kat ilerisinde.<\/p>\n
Verscharen, bu ara\u015ft\u0131rman\u0131n \u00e7\u0131kt\u0131lar\u0131n\u0131 birini daha a\u00e7\u0131klad\u0131. G\u00fcne\u015f’in manyetik alan\u0131n\u0131n birka\u00e7 dakika boyunca y\u00f6n\u00fcn\u00fc tersine \u00e7evirdi\u011fini ifade eden Verscharen, “Benzer bir \u015fey daha \u00f6nceki \u00e7al\u0131\u015fmalarda da g\u00f6r\u00fclm\u00fc\u015ft\u00fc ancak bu durumun bu kadar s\u0131k ya\u015fanaca\u011f\u0131n\u0131 tahmin edemezdik” dedi.<\/p>\n
Bu manyetik alan de\u011fi\u015fimlerinin g\u00fcne\u015f r\u00fczgarlar\u0131n\u0131n h\u0131z\u0131n\u0131n azal\u0131p artmas\u0131na neden oldu\u011fu ve b\u00f6ylelikle koronan\u0131n \u0131s\u0131nmas\u0131na katk\u0131da bulunabilece\u011fi d\u00fc\u015f\u00fcn\u00fclmekte.<\/p>\n
