contact binary

基本解釋

A contact binary star is a just-touching pair of stars that circle each other over a small period of time - in this case 1.4 days.
相接雙星是一組在短時(shí)間內(nèi)圍繞著彼此軌道所運(yùn)行的行星，v1309的情況則爲(wèi)1.4天。
Spending hours going through the images taken since 2002, he and his colleagues found light variations that suggested v1309 was originally a contact binary star.
這位科學(xué)家花費(fèi)了大量的時(shí)間來查閲望遠(yuǎn)鏡自2002年起所拍攝到的圖像，他與同事發(fā)現(xiàn)，從v1309所發(fā)出的亮光的變化上來看，它原屬於相接雙星。
Imagine for a moment that the contact binary had an inhabited planet with an advanced civilization. Its astronomers would have noted the shortening orbital period between the binary duo.
想象一下，假如密接雙星有一顆居住著擁有先進(jìn)文明的人類的行星，行星上的天文學(xué)者將會(huì)注意到兩個(gè)星星之間的軌道周期變短。
