A nuclear star cluster (NSC) or compact stellar nucleus (sometimes called young stellar nucleus) is a star cluster with high density and high luminosity near the center of mass of most galaxies. NSCs are the central massive objects of fainter, low-mass galaxies where supermassive black holes (SMBHs) are not present or are of negligible mass. In the most massive galaxies, NSCs are entirely absent. Some galaxies, including the Milky Way, are known to contain both a NSC and a SMBH of comparable mass.

  • 核星團(nuclear star cluster,NSC)或緻密星核(compact stellar nucleus,有時也稱為年輕星核)是在多數星系中,靠近其質量中心,有著高密度和高光度的恆星集團。 核星團是較暗的、低質量星系的中央大質量物體,而其中可能不存在超大質量黑洞或黑洞的質量可以忽略不計。在許多大質量星系中,完全沒有核星團。但有一些星系,包括銀河系,已知擁有超大質量黑洞和相當質量的核星團。 (zh)
