<\/span> Astronomlar, y\u0131ld\u0131zlar ve onlar\u0131n \u00e7evresindeki gezegenler aras\u0131ndaki karma\u015f\u0131k ve \u00e7o\u011fu zaman \u015fiddetli etkile\u015fimleri \u00e7\u00f6zmeye hen\u00fcz yeni ba\u015flam\u0131\u015f durumda. Bu ba\u011flamda dikkat \u00e7eken bir \u00f6rnek, s\u0131ra d\u0131\u015f\u0131<\/strong> d\u00f6nme hareketine sahip k\u0131rm\u0131z\u0131 dev y\u0131ld\u0131z Kepler-56<\/strong>. Ara\u015ft\u0131rmalar, y\u0131ld\u0131z\u0131n bu garip davran\u0131\u015f\u0131n\u0131n ge\u00e7mi\u015fte bir gezegenini yutmas\u0131ndan kaynaklanabilece\u011fini \u00f6ne s\u00fcr\u00fcyor. <\/figure>\n

Kepler-56\u2019n\u0131n \u00e7evresinde zaten bilinen iki \u00f6tegezegen bulunuyor. Ancak Tokyo \u00dcniversitesi Astronomi B\u00f6l\u00fcm\u00fc doktora \u00f6\u011frencisi Takato Tokuno, y\u0131ld\u0131z\u0131n al\u0131\u015f\u0131lmad\u0131k \u00f6zelliklerini inceledikten sonra, sistemin uzun zaman \u00f6nce kaybetti\u011fi bir \u201ckarde\u015f gezegeni\u201d olabilece\u011fini belirledi.<\/p>\n

Kepler-56\u2019\u0131n davran\u0131\u015f\u0131 ilgin\u00e7<\/b><\/p>\n

Y\u0131ld\u0131z\u0131n dikkat \u00e7ekici \u00f6zelliklerinden biri, d\u0131\u015f katman\u0131n\u0131n normal k\u0131rm\u0131z\u0131 dev y\u0131ld\u0131zlara g\u00f6re yakla\u015f\u0131k 10 kat daha h\u0131zl\u0131 d\u00f6nmesi<\/strong>. \u00dcstelik, y\u0131ld\u0131z\u0131n \u00e7ekirde\u011fi ve d\u0131\u015f katman\u0131 birbirine hizalanmam\u0131\u015f durumda<\/strong>. Yani d\u00f6nme y\u00f6neleri farkl\u0131.<\/p>\n

<\/span> Peki bu nas\u0131l m\u00fcmk\u00fcn olabilir? \u0130lk akla gelen a\u00e7\u0131klama, bilinen \u00f6tegezegenlerin etkisi. B\u00fcy\u00fck gezegenler, t\u0131pk\u0131 J\u00fcpiter\u2019in G\u00fcne\u015f\u2019i hafif\u00e7e sallamas\u0131 gibi y\u0131ld\u0131zlar\u0131n\u0131 \u00e7ekimsel olarak etkileyebilir. Ayr\u0131ca gezegenler, y\u0131ld\u0131zlar\u0131nda gelgitler yaratabilir. K\u00fc\u00e7\u00fck bir \u00e7ekim kuvveti bile, milyonlarca y\u0131l boyunca tekrarland\u0131\u011f\u0131nda, y\u0131ld\u0131z\u0131n d\u0131\u015f atmosferini h\u0131zland\u0131rabilir. E\u011fer gezegenler y\u0131ld\u0131z\u0131n d\u00f6nme ekseniyle hizalanmam\u0131\u015fsa, bu durum \u00e7ekirdek ve d\u0131\u015f katman aras\u0131nda hizalanma sorunlar\u0131na yol a\u00e7abilir. <\/figure>\n

Ancak Tokuno, bu senaryonun ger\u00e7ek\u00e7i olmad\u0131\u011f\u0131n\u0131 fark etti \u00e7\u00fcnk\u00fc gezegenlerin gelgitleri y\u00fckseltmek ve d\u00f6nme enerjisini y\u0131ld\u0131zlara aktarmak i\u00e7in di\u011fer sistemlerde g\u00f6r\u00fclenlerden \u00e7ok daha verimli bir yetenek gerektirecekti.<\/p>\n

Bir gezegeni yutmu\u015f olabilir<\/b><\/p>\n

<\/span> Tokuno\u2019ya g\u00f6re daha olas\u0131 senaryo, y\u0131ld\u0131z\u0131n bir gezegeni yutmu\u015f olmas\u0131<\/strong>. Bir y\u0131ld\u0131z gezegenini yuttu\u011funda, d\u00f6nme h\u0131z\u0131nda de\u011fi\u015fiklik meydana gelir. Tokuno, bunu D\u00fcnya\u2019ya \u00e7arpan dev bir meteorun enerjiyi aktararak D\u00fcnya\u2019y\u0131 h\u0131zland\u0131rmas\u0131na benzetiyor. E\u011fer gezegen y\u0131ld\u0131za al\u0131\u015f\u0131lmad\u0131k bir a\u00e7\u0131yla \u00e7arpt\u0131ysa, bu hem d\u0131\u015f katman ve \u00e7ekirdek aras\u0131ndaki uyumsuzlu\u011fu hem de h\u0131zl\u0131 d\u00f6nmeyi a\u00e7\u0131klayabilir. <\/figure>\n

Hen\u00fcz hakemli incelemeden ge\u00e7meyen ara\u015ft\u0131rmada bu senaryonun ger\u00e7ekle\u015febilmesi i\u00e7in yutulan gezegenin J\u00fcpiter k\u00fctlesinin yar\u0131s\u0131 ile iki kat\u0131 aras\u0131nda olmas\u0131 gerekti\u011fi hesapland\u0131. Ayr\u0131ca, \u00e7arp\u0131\u015fmadan hemen \u00f6nce y\u00f6r\u00fcngesinin bir ila alt\u0131 g\u00fcn aras\u0131nda d\u00f6nmesi gerekiyordu. Bu, tipik \u201cs\u0131cak J\u00fcpiter\u201d \u00f6tegezegenlerinin \u00f6zellikleriyle tamamen \u00f6rt\u00fc\u015f\u00fcyor.<\/p>\n

Makale, Kepler-56\u2019n\u0131n do\u011fdu\u011funda do\u011fal olarak y\u00fcksek bir d\u00f6nme h\u0131z\u0131na sahip olabilece\u011fini de olas\u0131l\u0131klar aras\u0131nda de\u011ferlendiriyor. Ancak bu varsay\u0131m, y\u0131ld\u0131z\u0131n \u00e7ekirde\u011fi ile d\u0131\u015f katman\u0131 aras\u0131ndaki hizalanma sorununu a\u00e7\u0131klam\u0131yor. Ayr\u0131ca, e\u011fer y\u0131ld\u0131z bu kadar h\u0131zl\u0131 do\u011fduysa, astronomlar i\u00e7in yeni bir soru ortaya \u00e7\u0131k\u0131yor: Bir y\u0131ld\u0131z do\u011fdu\u011funda neden bu kadar h\u0131zl\u0131 d\u00f6ner? Tokuno\u2019ya g\u00f6re bir olas\u0131l\u0131k, y\u0131ld\u0131z\u0131n gen\u00e7 ya\u015fta bir gezegeni yutarak enerjisini art\u0131rm\u0131\u015f olmas\u0131. B\u00f6yle bir \u00e7arp\u0131\u015fma, hem y\u00fcksek d\u00f6nme h\u0131z\u0131n\u0131 hem de \u00e7ekirdek ve d\u0131\u015f katman aras\u0131ndaki uyumsuzlu\u011fu a\u00e7\u0131klayabilir.<\/p>\n\n
