(The Turkish Post) –<\/strong> Bilim insanlar\u0131 ilk kez laboratuvar ortam\u0131nda G\u00fcne\u015f parlamalar\u0131 olu\u015fturdu.<\/p>\n

Bu devasa plazma bulutlar\u0131 son derece b\u00fcy\u00fck. Uzmanlara g\u00f6re bunlar D\u00fcnya’n\u0131n birka\u00e7 kat\u0131 boyuta ula\u015fabiliyor.<\/p>\n

ABD’deki Kaliforniya Teknoloji Enstit\u00fcs\u00fc’nden ara\u015ft\u0131rmac\u0131lar ise laboratuvar ortam\u0131nda bir \u00e7antaya s\u0131\u011fabilecek kadar k\u00fc\u00e7\u00fck G\u00fcne\u015f parlamalar\u0131 \u00fcretildi.<\/p>\n

K\u0131saca CME diye adland\u0131r\u0131lan koronal k\u00fctle at\u0131m\u0131, D\u00fcnya’ya radyoaktif plazma dalgalar\u0131n\u0131n ula\u015fmas\u0131na neden olabiliyor. Bu duruma da G\u00fcne\u015f f\u0131rt\u0131nas\u0131 ad\u0131 veriliyor.<\/p>\n

G\u00fcne\u015f f\u0131rt\u0131nalar\u0131 y\u00f6r\u00fcngedeki uydular\u0131 ve astronotlar\u0131 tehlikeye atabildi\u011fi gibi D\u00fcnya y\u00fczeyinde de GPS, navigasyon sistemleri ve radyo ileti\u015fiminin aksamas\u0131na yol a\u00e7abiliyor.<\/p>\n

Ara\u015ft\u0131rmac\u0131lar uzun s\u00fcredir D\u00fcnya’y\u0131 jeomanyetik f\u0131rt\u0131nalar\u0131n etkilerinden koruyacak \u00f6nlemler geli\u015ftirebilmek i\u00e7in u\u011fra\u015f\u0131yor.<\/p>\n

Bu y\u00fczden y\u0131ld\u0131zdaki patlamalar\u0131 yak\u0131ndan incelemek ve\u00a0 G\u00fcne\u015f’teki korona d\u00f6ng\u00fclerinde ortaya \u00e7\u0131kan parlamalar\u0131n G\u00fcne\u015f f\u0131rt\u0131nalar\u0131na nas\u0131l d\u00f6n\u00fc\u015ft\u00fc\u011f\u00fcn\u00fc anlamak \u00e7ok \u00f6nemli.<\/p>\n

Hakemli bilimsel dergi Nature Astronomy’de yay\u0131mlanan son \u00e7al\u0131\u015fmada ara\u015ft\u0131rmac\u0131lar, bu gizemi \u00e7\u00f6zmek i\u00e7in kendi korona d\u00f6ng\u00fclerini yaratt\u0131.<\/p>\n

Ekip, manyetize edilmi\u015f, gazla dolu bir odan\u0131n i\u00e7indeki bir \u00e7ift elektrottan elektrik bo\u015faltt\u0131. Elektrik, gaz\u0131 iyonla\u015ft\u0131rd\u0131 ve iki elektrot aras\u0131nda bir plazma dizisi olu\u015fturdu.<\/p>\n

Bu plazma dizisi odan\u0131n manyetik alan\u0131 taraf\u0131ndan k\u0131sa bir s\u00fcre boyunca d\u00f6ng\u00fc halinde yerinde tutuldu. Ancak sonra i\u00e7ine do\u011fru \u00e7\u00f6kerek d\u0131\u015far\u0131 do\u011fru p\u00fcsk\u00fcren k\u00fc\u00e7\u00fck bir parlamay\u0131 meydana getirdi.<\/p>\n

Normalde gezegenlerin boyutlar\u0131n\u0131 a\u015fan bu d\u00f6ng\u00fcler, laboratuvar ortam\u0131nda sadece 20 santimetre uzunlu\u011fundayd\u0131. Di\u011fer bir deyi\u015fle bir muzla hemen hemen ayn\u0131 boyuttayd\u0131 ve yakla\u015f\u0131k 10 mikrosaniye s\u00fcrd\u00fc.<\/p>\n

Saniyede 10 milyon kare yakalayan \u00f6zel kameralar sayesinde ara\u015ft\u0131rmac\u0131lar, d\u00f6ng\u00fclerin nas\u0131l b\u00fcy\u00fcd\u00fc\u011f\u00fcn\u00fc ve sonra par\u00e7aland\u0131\u011f\u0131n\u0131 g\u00f6zlemledi.<\/p>\n

Ara\u015ft\u0131rmac\u0131lar, s\u00f6z konusu plazma dizilerin bir ip gibi ince \u015feritlerden olu\u015ftu\u011funu tespit etti.<\/p>\n

Ara\u015ft\u0131rman\u0131n yazarlar\u0131ndan Yang Zhang, “Bir ipi par\u00e7alara ay\u0131r\u0131rsan\u0131z, ayr\u0131 ayr\u0131 ipliklerden olu\u015fan \u00f6rg\u00fclerden meydana geldi\u011fini g\u00f6r\u00fcrs\u00fcn\u00fcz.
