核星团及其宿主星系团的性质

The Properties of Nuclear Star Clusters and their Host Galaxies

Anil C. Seth, Nadine Neumayer, Torsten Boeker

摘要:

大多数星系的中心都有核星团。它们是宇宙中最密集的恒星系统,因此具有独特而有趣的恒星动力学。我们回顾了不同质量和类型的星系中常见的核星团,然后讨论了NSC的典型性质。最后,我们讨论了NSC的形成,以及如何在低质量和高质量星系中占主导地位的不同形成机制的图片正在出现。

英文摘要:

Nuclear star clusters are found at the centers of most galaxies. They are the densest stellar systems in the Universe, and thus have unique and interesting stellar dynamics. We review how common nuclear star clusters are in galaxies of different masses and types, and then discuss the typical properties of NSCs. We close by discussing the formation of NSCs, and how a picture is emerging of different formation mechanisms being dominant in lower and higher mass galaxies.
