球状星团![]() ![]() ![]() ![]() 球状星团是外观呈球形,在轨道上绕着星系核心运行,很像卫星的恒星集团。球状星团因为被重力紧紧束缚,使得恒星高度的向中心集中,因此外观呈球形。此类别星团的名称源自拉丁文的globulus -小的球体,因此球状星团有时也会被简称为球。 球状星团被发现多在星系的晕之中,远比在星系盘中被发现的疏散星团拥有更多的恒星,但球状星团的数量相较疏散星团相对的稀少,在银河系内迄今只发现大约150余个 to 158。在银河系内也许还有10- 20个或更多个尚未被发现。这些球状星团环绕星系公转的半径可以达到40,000秒差距(大约130,000光年)或更远的距离。越大的星系拥有越多:以仙女座星系为例,可能有500个球状星团。有些巨大的椭圆星系,特别是位于星系团中心的,像是M87,有多达13,000个球状星团。
英语百科
Globular cluster 球状星团![]() ![]() ![]() ![]() A globular cluster is a spherical collection of stars that orbits a galactic core as a satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centers. The name of this category of star cluster is derived from the Latin globulus—a small sphere. A globular cluster is sometimes known more simply as a globular. |
