食双星

To be more precise, however, Algol happens to be a triple star system: the eclipsing binary pair is separated by only 0.062

更精确的说，大陵五实际上是一组三合星：成对的食双星分隔的距离只有0.062

A new object looking like an eclipsing binary star was discovered recently.

最近人们发现了一个象食变双星的新天体。

As an eclipsing binary, it is actually two stars in close orbit around one another.

作为食双星，它实际上是两颗在接近的轨道上互绕的恒星。

Sure enough, they saw a dip in light where the new eclipsing binary resides.

果然，研究人员在这对新发现的食双星座落的地方观察到光线变暗的情况。

Astronomers study these eclipsing binary events to learn more about the evolution of stars.

天文学家研究&食双星&以便更多地了解恒星演化。

In eclipsing binaries, the two stars as viewed from Earth revolve around an axis that is edge-on to us.

在食双星的情况中，从地球上来看两颗恒星在围绕着一条侧向我们的轴旋转。

W UMa systems are very common, comprising some 95 per cent of eclipsing variables in the solar neighbourhood.

相接双星的存在又十分普遍，在太阳系附近，95％的食双星都是W UMa型相接双星。

For centuries, astronomers had not been able to figure out the nature of this "eclipsing binary system," in which a bright naked-eye star is eclipsed by a companion object every 27 years.

一个多世纪来，天文学家一直没搞清柱一&食双星&的性质，这颗肉眼可见明亮恒星，以27年的周期改变光度。

One theory holds that the bright star is a massive supergiant, periodically eclipsed by two tight-knit stars inside a swirling, dusty disk. The second theory holds that the bright star is in fact a dying star with a lot less mass, periodically eclipsed by just a single star inside a disk.

这两个理论，一个认为亮主星是颗超巨星，周期性地被一个由尘埃围绕的密近双星系统所掩食；而另一个认为亮主星其实是颗已经流失大量质量的垂死恒星，而尘埃云中的伴星也只有一颗。

Epsilon Aurigae is a visually bright, eclipsing binary star system with a period of 27.1years.

柱一是明亮的食双星，互绕周期为27.1年。

And unto the angel of the church in Sardis write; These things saith he that hath the seven irits of God, and the seven star I know thy works, that thou hast a name that thou livest, and art dead.

3：1 你要写信给撒狄教会的使者，说，那有神的七灵和七星的，说，我知道你的行为，按名你是活的，其实是死的。
