globular cluster

基本解释

Like a whirl of shiny flakes sparkling in a snow globe, Hubble caught this glimpse of stars in the globular cluster M13.
哈勃在球状星团M13中拍到这些星星的一撇，它像雪球中闪闪发光的光片旋涡。
Another interesting aspect to this object is that it is found within a globular cluster, a very old, very tight grouping of stars.
这个物体另一个有趣的一面是，它是在一个球状星团中，一个很古老很紧密星群中被发现。
Evidence from NASA's Chandra X-rayObservatory and the Magellan telescopes suggest a star was torn apartby an intermediate-mass black hole in a globular cluster.
来自美国宇航局的钱德拉X射线天文台和麦哲伦望远镜证据表明恒星被一个球状星团的中等大小黑洞撕裂。

Now, astronomers have scoured one of the few suspected hiding spots for medium-sized black holes in a globular cluster, and conclude they are rare or nonexistent.
MSN: Existence of middleweight black holes nearly ruled out

a densely populated spheroidal star cluster with the highest concentration of stars near its centre, found in the galactic halo and in other galaxies

球状星团
For example, models and isochrones appropriate for globular cluster stars have shown that the inclusion of diffusion reduces the main sequence lifetime and effective temperatures of the stars.
例如,通过讨论球状星团恒星的模型和等时线发现元素扩散可以减少恒星主序阶段的年龄同时降低恒星表面的有效温度。
