It is then referred to as a White Dwarf.

这时,它被称为白矮星.

Eight different white dwarf systems were examined.

他们)研究过八个不同的白矮星系.

If a binary includes a white dwarf, gas pulled from a companion onto the white dwarf's surface can fuse violently in a flash called a nova.

如果一个双星系统包含一个白矮星，从伴星上抽离的气体会落在白矮星的表面，在一瞬间引发猛烈的聚变反应，即新星。

Or, it seems, when you're cruising past a white dwarf star.

或者可以说在你缓慢驶过一颗白矮星时。

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。

When a star collapses, it will be White dwarf or Supernova.

当恒星塌陷时，它会变成白矮星或者超新星。

The researchers suggest that there are many white dwarf stars throughout this halo.

研究人员猜想,光晕内到处有白矮星.

Theory predicts that a white dwarf star will explode when infalling matter from a companion star increases the mass of the white dwarf beyond a critical mass limit, known as the Chandrasekhar limit.

理论预言，当来自伴星的物质让白矮星的质量增加到了临界质量极限即钱德拉塞卡极限时，白矮星就会爆发。

The sun's upper layers will expand and lose material, and eventually the core will cool enough to become a white dwarf star,and finally a black dwarf.

太阳的上层也将扩大，失去物质重量，最后中心冷却到一定程度就成了白矮星，最终成黑矮星。

Just like corporations, stars, too, can engage in mergers and acquisitions: a new study has identified a pair of white dwarf stars heading toward a merger.

就像企业一样，星星也能进行“合并和收购”：经研究确定一对白矮星正走向合并。
