恒星的

To make such swift progress, the planet circles extremely close-in to its star — about 2 percent of the distance from the Earth to the sun, in fact, or 2 million miles (3.4 million kilometers).

该行星必须在特别近的距离上环绕其恒星，才能运行得如此之快。事实上，这颗行星跟其恒星的距离只有地球到太阳距离的百分之二，换句话说，只有两百万英里（340万公里）。

They are, however, known to develop out of the leftover, typically disk-shaped mass of gas and dust that swirls around a newborn star, so whatever direction that material is moving, which is the direction of the star's rotation, becomes the direction of the planet's orbit.

不过，据认为它们是有残留物产生，通常残留物是在新生恒星周围旋转的碟型气体和尘埃团，所以，那种物质做什么运动--即恒星的自转方向--都会成为卫星轨道环绕运动方向。

Depending on the details, the gas orbiting star/protostar may be unstable and start to compress under its own gravity.

基于详细资料，围绕恒星、原恒星的气体会变得不稳定，然后开始在自己的重力下开始压缩。

It would maneuver to a position along the line of sight between the telescope and a nearby star.

它能够移动至望远镜与恒星的视线中间，阻挡恒星的辐射，使其行星能被观测得到。

The observation confirmed a decade of speculation that a warp in the young star's dust disk may actually be a second disk inclined to the star.

这项观测确定了10年来的推测学说，即年轻恒星的尘埃盘可能实际上时第二个尘埃盘向恒星一侧倾斜。

Highly energetic X-rays are also detected from the young star, partially absorbed by streams of material flowing from the disk onto the star.

年轻恒星的高能x射线同样被探测到，部分通过从圆盘到恒星的物质流吸收。

Because no light escapes after the star reaches this infinite density, it is called a black hole.

当恒星的密度达到无穷大时，因为光也逃离不了它，此时的恒星就叫做黑洞。

If there were in fact rocky planets within the inner gap between the star and asteroid belt, the worlds would likely reside within the star's habitable zone where temperatures would be such that life could survive.

如果在恒星和小行星带之间的内围间隙中确实存在岩石行星，那么这些星球可能会位于这颗恒星的可居住带上，其温度可能会适于生命生存。

Just"new Earth" of the detection of mother fixed star Gliese 581 distance the Earth only have 20.5 light year, is leave the Earth recent of 100 one of the fixed stars.

只是&地球母亲的检测&葛利斯581恒星的距离地球只有20.5光年，是离开地球100恒星固定行星。

The evolution of fixed star having something to do with nuclear reaction, the star generally loses partial mass in ...

恒星的演化与核反应有关，演化到晚期的恒星一般要损失一部分质量，然后坍缩成致密星。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
