...由10颗以上的恒星,各成员间因引力束缚而聚在一起的恒星群,我们称之为星团,依其形态可分为两种:球状星团(globular cluster):外形呈球状对称或接近球状对称而得名,星团内的恒星十分密集,由数千甚至数十万颗恒星所组成的集团,直径约 100光年。

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。
