Mass segregation in clusters: analytic estimation of the timescale.
MOURI H. and TANIGUCHI Y.
Abstract (from CDS):
Mass segregation in a star cluster is studied in an analytical manner. We consider a two-component cluster, which consists of two types of stars with different masses. Plummer's model is used for the initial condition. We trace the overall behaviors of the probability distribution functions of the two components and obtain the timescale of mass segregation as a simple function of the cluster parameters. The result is used to discuss the origin of a black hole with mass of ≳103M☉found in the starburst galaxy M82.
