Anisotropic Mass Segregation in Rotating Globular Clusters

ASTROPHYSICAL JOURNAL American Astronomical Society 887:2 (2019) ARTN 123

Authors:

Akos Szolgyen, Yohai Meiron, Bence Kocsis

Abstract:

We investigate the internal dynamics of anisotropic, rotating globular clusters with a multimass stellar population by performing new direct N-body simulations. In addition to the well-known radial mass segregation effect, where heavy stars and stellar remnants sink toward the center of the cluster, we find a mass segregation in the distribution of orbital inclinations as well. This newly discovered anisotropic mass segregation leads to the formation of a disk-like structure of massive objects near the equatorial plane of a rotating cluster. This result has important implications on the expected spatial distribution of black holes in globular clusters.
