Those are amazing objects in their own right, and also rather rare perhaps because they're so difficult to spot: there's eight known white dwarfs in the hundred nearest star systems to our sun.
白矮星是具个性的，也是非常稀有可能因为定位它们很困难令人惊异的恒星，在上百个离我们的太阳最近的星系中只有八颗已知的白矮星。 yeeyan
When they reach the end of their long evolutions, smaller stars— those up to eight times as massive as our own sun— typically become white dwarfs.
一般来说，较小的恒星——也就是那些体积达我们的太阳八倍大小的恒星——在它们漫长演化过程的终点，就会变成白矮星。 yeeyan
Another intriguing consequence of this result is that a pair of white dwarfs is relatively hard to spot, even with the best telescopes.
这一结果带来的另一条让人感兴趣的推论是，白矮星双星相对难以探测，哪怕是使用最好的望远镜。 blog.sina.com.cn
Because white dwarfs can come in a range of masses, the merger of two could result in explosions that vary somewhat in brightness.
由于白矮星的质量处在有个亿范围之内，两个星体的并合会导致亮度有些许变化的爆发。 blog.sina.com.cn
But about20 per cent of white dwarfs are tainted by traces of heavier elements.
但是大约20%的白矮星都有着重元素污染的痕迹。 yeeyan
Carbon Earths might be especially prevalent in more bizarre settings, such as the environs of white dwarfs and neutron stars.

During the radiation stars will develop in turn into main sequence stars, red giants, white dwarfs or neutron stars, etc.
在历经主序星、红巨星和白矮星或中子星后演化为致密星体而结束一生。 cnki
Estimating how long white dwarfs have been cooling can help astronomers learn much about the age of the universe.
估算白矮星冷却的时间长度有助于天文学家深入研究宇宙的年龄。 yeeyan
In general, the heavier atoms in the atmosphere sink and the light ones remain at the surface, which is why some white dwarfs, for example, have mostly pure hydrogen or helium atmospheres.
总体来说，较重的原子在大气圈中沉积，而较轻的原子则存在于大气圈表面，这也是一些白矮星具有较纯净的氢和氦大气圈的原因。 yeeyan
One class of white dwarfs has almost pure helium atmospheres.
有一类白矮星的大气层几乎完全由纯氦气构成。 yeeyan
Our current theoretical models of white dwarfs don't predict this sort of behavior.
目前白矮星的理论模型不能模拟这种行为。 yeeyan
Professional and amateur astronomers have embarked on a survey of thousands of white dwarfs to check for evidence of such planets, Agol says.
阿戈尔说，为了搜寻这种行星的迹象，职业天文学家们和业余天文爱好者们已经开始行动了，他们正在审视成千上万颗白矮星。 yeeyan
Stars like our sun fuse hydrogen in their cores into helium. White dwarfs are stars that have burned up all of the hydrogen they once used as nuclear fuel.
太阳一类的恒星在其核心将氢融合成氦。而白矮星则是将其曾用作核燃料的所有氢原子都燃烧殆尽的恒星。 yeeyan
The white dwarfs are gradually spiraling toward each other at breakneck speeds of370 miles595 kilometers a second, and they're destined to merge in900,000 years.
这两颗白矮星以每秒370英里合595公理的超高速度旋转着向对方靠近，它们将在900000年后与对方汇聚。 yeeyan
