恒星

Hellier's report on the suicidal planet is in Thursday's issue of the journal Nature.

他说：&WASP-18b在引发所绕恒星等离子潮的同时也让自己走向毁灭之路。&

Bright spots in the Horsehead Nebula 's base are young stars just in the process of forming .

马头星云中的那些明亮的点都是一些正在形成的明亮恒星。

Evolution of stars of all masses takes place on a hydrodynamic time scale.

各种质量的恒星的演化，均以流体力学的时间尺度进行。

From Karlsson's formula and the polar effect, we realize that the half periodic parameter of redshift is 0.206, in theory, we finally explain why the great wall is at redshift Z=0.079 in redshift space; We have defined quasar as the early star nearby the position poles and opposite poles, and given the answer for two difficult problems of theirs; Based on the course of explanation for redshift space, we have reason to think that our universe might be the linear expansion hyperspherical universe.

从Karlsson公式及极点效应，我们认识到红移的半周期参数为0.206，最终从理论上解释了为什么红移长城在红移空间的位置为 Z=0.079；我们定义类星体为在位置极点和异极点附近的早期恒星，进而给出与其相关的两个难题的答案；基于对红移空间的解释过程，我们有理由认为我们的宇宙是线性膨胀超球面宇宙。

By analyzing numerically the disks around a young stellar object and a black hole, we can obtain: the dissipation can not be neglected as a magnetic field is in small threshold value; in Keplerian disks, the magnetic field is smaller, the dissipation caused by anomalous viscosity and anomalous resistivity deviates from the ideal more greatly; the dissipative effects on magnetic instability become smaller as the radius r becomes larger.

通过分析年轻恒星周围和黑洞周围吸积盘的数值解可以得到：在磁场比较小的一段阈值内，这种耗散过程是不可忽略的；而且，磁场越小，由反常黏滞及反常阻抗引起的耗散过程对磁不稳定性的影响就越大；离中心体的距离r越大，耗散过程对磁不稳定性的影响越小。

Gamma Leonis is the brightest star in these two panels, while the second brightest star, 40 Leonis, is directy to its right.

伽玛莱奥尼斯是在这两个小组亮的星星，而第二亮的恒星，40莱奥尼斯，是directy其权利。

The two bright objects that look like car headlights are a pair of stars in the Large Magellanic Cloud.

两个看上去像车灯的明亮的物体是在大麦哲伦星云中的一对恒星。

Astronomers are especially keen to study star formation in the Small Magellanic Cloud, because its chemical composition is different from that of the Milky Way.

天文学家们对小麦哲伦星云中恒星的形成一直和热衷，因为，小麦哲伦星云的化学组成和银河系的不同。

Doradus Nebula in the Large Magellanic Cloud is a of turbulent star-forming regions.

剑鱼座30星云是一个位于大麦哲伦云的动荡的恒星形成区。

On February 23, 1987, a star about 15 times in solar mass exploded in the Large Magellanic Cloud, a satellite galaxy of our own Galaxy.

1987年2月23日，一颗比太阳重15倍的恒星，在银河系的邻近星系—大麦哲伦云内爆发。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
