伴星

The brightest star in the nighttime sky, Sirius, or the Dog Star, greatly outshines its white dwarf companion, Sirius B. At 8.6 light-years away, Sirius is the nearest star to Earth.

夜空中最亮的一颗星，天狼星，或者叫&犬狼星&，其光芒远远胜过它的白矮星伴星，在8.6光年外的天狼星是距地球最近的一颗恒星。

If they assumed the F star was actually a much less massive, dying star, and they also assumed that the eclipsing object was a single B star embedded in the dusty disk, everything snapped together.

假如把F型超巨星假设为一个质量小得多的垂死恒星，并假设伴星是一个深嵌于尘埃盘中的B型星，所有的数据都对上了。

The blue data show light from the companion object, a so-called B star, while the light yellow data show light from the main bright star, called an F star.

蓝色部分的星光来自伴星，是一颗B型星；黄色部分星光来自明亮的主星，是一颗F型星。

Adopting a mass of 5.9M⊙ for the B star, we derive a mass of ~(3.6±0.7)M⊙ for the F star.

我们的数据支持：伴星质量约5.9个太阳，主星质量约3.6±0.7个太阳。

The orbital elements imply that the opaque object has roughly the same mass as the visible component, which for much of the last century was thought to be an F-type supergiant star with a mass of ~15M⊙(M⊙, mass of the Sun).

根据轨道根数，一般近似地认为不透明伴星与明亮的主星质量相当，而上世纪主流的观点认为主星是15个太阳质量左右的F型超巨星。

Astronomy the alignment of the Earth and a planet on the same side of the sun.

较小天体或伴星比它所绕转的主星更近观测者的一次合。

In this model, gas flows from the large red giant companion star into a disk and then onto the white dwarf.

这个模型是指气体从大型红巨星伴星流到白矮星的吸积盘上然后被吸进白矮星中。

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。

The main stars of blue, yellow companion star.

主星为蓝色，伴星为黄色。

NORTH STAR TRIPLE THREAT: The North Star is not a single star, but rather a triple tar system consisting of Polaris and two companions.

北极星并非一个孤单的星星，而是一个三星系统，还包含着两个伴星。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
