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.
相接双星是一组在短时间内围绕着彼此轨道所运行的行星，v1309的情况则为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.
这位科学家花费了大量的时间来查阅望远镜自2002年起所拍摄到的图像，他与同事发现，从v1309所发出的亮光的变化上来看，它原属于相接双星。
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，假如密接双星有一颗居住着拥有先进文明的人类的行星，行星上的天文学者将会注意到两个星星之间的轨道周期变短。
