D\u00fcnya’dan sadece 12 \u0131\u015f\u0131k y\u0131l\u0131 uzakl\u0131kta bulunan, G\u00fcne\u015f benzeri y\u0131ld\u0131z Tau Ceti’nin y\u00f6r\u00fcngesindeki 2 gezegenin ya\u015fama elveri\u015fli olabilece\u011fi belirtildi.<\/p>\n

\u0130ngiltere, Hertfordshire \u00dcniversitesinden Fabo Feng \u00f6nderli\u011finde y\u00fcr\u00fct\u00fclen ara\u015ft\u0131rmada, Doppler Spectroscopy (radyal h\u0131z ya da titre\u015fim metodu) ad\u0131 verilen y\u00f6ntemle, Tau Ceti’nin deviniminde, y\u00f6r\u00fcngesinde k\u00fc\u00e7\u00fck gezegenlerin yer \u00e7ekimi kuvvetinden kaynaklanan zay\u0131f titre\u015fimler oldu\u011fu tespit edildi.<\/p>\n
Y\u00f6ntemin, Tau Ceti’nin devinim varyasyonlar\u0131n\u0131n saniyede 30 santimetre kadar d\u00fc\u015f\u00fck oldu\u011funu g\u00f6sterdi\u011fi kaydedildi.<\/p>\n
Titre\u015fimler sayesinde y\u0131ld\u0131z\u0131n y\u00f6r\u00fcngesinde 4 gezegen oldu\u011fu belirlendi.<\/p>\n
Bu gezegenlerden 2’sinin, ya\u015fam i\u00e7in elveri\u015fli ko\u015fullara sahip olabilece\u011fini ifade eden bilim adamlar\u0131, bunlar\u0131n y\u0131ld\u0131za konumlar\u0131n\u0131n da y\u00fczeylerinde su bulunabilece\u011fine i\u015faret etti\u011fini bildirdi.<\/p>\n
Y\u0131ld\u0131za \u00e7ok yak\u0131n mesafesi nedeniyle di\u011fer 2 gezegenin ise y\u00fczeylerinde su olmayaca\u011f\u0131 d\u00fc\u015f\u00fcn\u00fcl\u00fcyor.<\/p>\n
Daha \u00f6nce Tau Ceti’yi inceleyen ayn\u0131 ekip, y\u0131ld\u0131z\u0131n y\u00f6r\u00fcngesindeki gezegen say\u0131s\u0131n\u0131n 5 oldu\u011funu varsay\u0131yordu.<\/p>\n
\u00d6te yandan bilim adamlar\u0131, ke\u015fif konusunda heyecana kap\u0131l\u0131nmamas\u0131 gerekti\u011fini, Tau Ceti sistemini \u00e7evreleyen ve uzay \u00e7\u00f6plerinden olu\u015fan devasa halkan\u0131n, gezegenlerin asteroit sald\u0131r\u0131lar\u0131n\u0131n tehdidi alt\u0131nda olabilece\u011fini g\u00f6sterdi\u011fini dile getirdi.<\/p>\n
