contact binary

基本解释

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間內圍繞著彼此軌道所運行的行星，v1309的情況則爲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.
這位科學家花費了大量的時間來查閲望遠鏡自2002年起所拍攝到的圖像，他與同事發現，從v1309所發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文明的人類的行星，行星上的天文學者將會注意到兩個星星之間的軌道周期變短。
