Bilim insanlar\u0131, yeni ke\u015ffedilen TRAPPIST-1 y\u0131ld\u0131z sistemindeki 7 gezegenin ortalama \u00f6z k\u00fctlesinin benzer oldu\u011funu belirledi.<\/p>\n
ABD’nin Washington \u00dcniversitesinde bilim insanlar\u0131, sonu\u00e7lar\u0131n\u0131 “Planetary Science Journal” dergisinde yay\u0131mlad\u0131klar\u0131 ara\u015ft\u0131rmada, D\u00fcnya’ya 40 \u0131\u015f\u0131k y\u0131l\u0131 mesafedeki TRAPPIST-1 adl\u0131 k\u0131z\u0131l c\u00fcce y\u0131ld\u0131z\u0131n\u0131n y\u00f6r\u00fcngesindeki \u00f6te gezegenlerin k\u00fctle ve hacimlerinin detayl\u0131 \u00f6l\u00e7\u00fcmlerini yapt\u0131.<\/p>\n
Gezegenlerin y\u00f6r\u00fcngesindeki y\u0131ld\u0131z ile D\u00fcnya aras\u0131nda g\u00f6zlemlenebilir oldu\u011fu “ge\u00e7i\u015f zaman\u0131 varyasyonlar\u0131n\u0131” (TTV) inceleyen bilim insanlar\u0131, D\u00fcnya’ya yak\u0131n boyutlardaki g\u00f6k cisimlerinin dikkate de\u011fer \u015fekilde benzer ortalama \u00f6z k\u00fctleye sahip oldu\u011funu tespit etti.<\/p>\n
Bilim insanlar\u0131 daha \u00f6nce D\u00fcnya’ya benzer kaya\u00e7 yap\u0131da oldu\u011fu tahmin edilen gezegenlerin, oksijen, demir, magnezyum ve silikon bile\u015fiminden olu\u015ftu\u011fu ve s\u00f6z konusu maddeleri benzer oranlarda i\u00e7erdi\u011fi sonucuna vard\u0131.<\/p>\n
Ara\u015ft\u0131rmac\u0131lar, gezegenlerin \u00f6z k\u00fctlelerinin D\u00fcnya’dan y\u00fczde 8 daha d\u00fc\u015f\u00fck oldu\u011funu tespit ederken, bunun madde kompozisyonunun farkl\u0131 olmas\u0131ndan kaynakland\u0131\u011f\u0131n\u0131 d\u00fc\u015f\u00fcn\u00fcyorlar.<\/p>\n
Fizikte \u00f6z k\u00fctle, bir maddenin birim hacminin k\u00fctlesi, yani onun yo\u011funlu\u011fu olarak tan\u0131mlan\u0131yor.<\/p>\n
D\u00fcnya’ya 40 \u0131\u015f\u0131k y\u0131l\u0131 mesafedeki TRAPPIST-1 sisteminde yer alan gezegenlerden \u00fc\u00e7\u00fc, ilk kez 2015’te Avrupa G\u00fcney G\u00f6zlemevinin Ge\u00e7i\u015f Halindeki Gezegen ve Gezegensiler K\u00fc\u00e7\u00fck Teleskobu (TRAPPIST) taraf\u0131ndan ke\u015ffedilmi\u015fti.<\/p>\n
Amerikan Havac\u0131l\u0131k ve Uzay Ajans\u0131 (NASA), 2017’de sistemde toplam 7 gezegen oldu\u011funu, bunlar\u0131n hepsinin y\u0131ld\u0131z\u0131n canl\u0131 ya\u015fam\u0131n\u0131n ortaya \u00e7\u0131kmas\u0131na m\u00fcsait ya\u015fanabilir b\u00f6l\u00fcm\u00fcnde bulundu\u011funu a\u00e7\u0131klam\u0131\u015ft\u0131.<\/p>\n
