If you have a binary system whereby both stars are visible so you get the spectrum of both stars, then you see the Doppler shift of both stars in the spectrum.
若存在一个双星系统，两颗恒星均看不见，你能得到双星的光谱，然后在光谱中看到，双星的多普勒顿移。
In addition, spectroscopic observations with ground-based telescopes further reveal that one of the stars is actually a tight binary that is too compact to be resolved even by Hubble.
另外，地面望远镜的分光镜观察结果进一步揭示出它们其中的一颗恒星实际上是一对紧密的双星组成的，它们距离太近以至于哈勃望远镜不能区分出来。
Two such stars rotating around each other would form a binary system, getting closer and closer until they merged in a violent explosion.
两颗中子星互相绕行形成一个双星系统，它们越靠越近直到它们在爆炸中融合。
Sometimes, however, the system's overall brightness dipped even when the stars were not eclipsing each other-hinting at the presence of a third body orbiting the binary pair.
但有时，即使当系统在没有相互重叠时，这一对恒星的整体亮度也会明显下降——暗示着，还有第三个物体围绕着这一对恒星作轨道运转。
The binary star system consists of two white dwarfs—the burnt-out cores of sunlike stars.
该双星系统由两颗白矮星组成——所谓白矮星既是像太阳那样的恒星燃烧殆尽后遗留下来的核心。
That's unfortunate since many stars are not solitary but members of a binary system.
