The result shows that only longituds of starspots can be obtaind:Φspot～Ψ|△lmax In the other aspect,appling Doppler imaging process,We must solve an in tegral equation of the form:As a result,if the photo ele ctric method and Doppler imaging process were linked,the parameters of.

目前，研究恒星黑子主要采用测光和多卜勒成像两种方法。

Black Hole Seen Ripping Star Apart

超大黑洞引力无穷 恒星不幸惨遭分身

A black hole is one of the last options that a star may take.

恒星演变的最后一种可能就是黑洞。

There is also dark matter - the material between the stars and planets.

其实还有黑洞??一种介于恒星与行星间的物质。

The black hole could then grow even stronger (from the star's mass) as to possibly absorb another.

吸收了恒星质量之后，黑洞进一步膨大，并有可能吞噬下一颗恒星。

Black holes are the evolutionary endpoints of stars at least 10 to 15 times as massive as the Sun.

黑洞是恒星演化的终点，这些恒星的质量通常有10－15个太阳大

interstellar space including streams of protons moving from the stars.

星际空间中的从恒星发出的质子流。

3 the cloud from which a star is formed contains enough molecules to form numerous stars.

形成一颗恒星的星云内含有足以形成无数恒星的分子。

And from the remains of a dying star a black hole is born.

这时，黑洞便在濒死恒星的遗体之内降生。

Stars are as thick as the sand grains on a beach.

恒星像海滩上的沙子那样密集。

Every star is a copious source of neutrinos.

每颗恒星都是丰富的中微子源。

Neutron stars are the second exhibit in the gallery of stellar corpses.

中子星是死之恒星陈列馆内第二类样品。

The Collapse of the Molecular Cloud Core in the Formation of the Star and Planet;

恒星与行星的形成过程中的分子云核坍塌

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。

All black holes are formed from the gravitational collapse of a star, usually having a great, massive, core.

所有的黑洞都是因为恒星的引力坍缩而形成，这种恒星通常有一颗巨大而厚重的核心。

When a black hole absorbs a star, the star is first pulled into the Ergosphere, which sweeps all the matter into the Event Horizon.

当黑洞吸入恒星时，恒星先是被吸到能层，能层又将所有的物质卷进事界。

However, if a black hole passes through a cloud of interstellar matter, or is close to another "normal" star, the black hole can accrete matter into itself.

然而，当一个黑洞穿过一片星云，或者靠近另一个正常恒星时，黑洞将会使它自身的物质增加。

Light from ordinary stars and galaxies comes largely from atoms powered by thermonuclear reactions in the hearts of stars.

来自一般恒星和星系的光，主要是那些受恒星内部的热核反应所激发的原子发射出的。
