Abstract

We investigate with numerical Af-body integrations the time-evolution of stellar systems with centrally peaked density profiles harboring a massive black hole (galactic nuclei) or with varied initial conditions (such as rotation) using directintegration integrators. The computer programmes EUROSTAR and NBODY6++ developped for use with mpi libraries maintain high accuracy over billions of integration timesteps, allowing a detailed analysis of the orbit of the black hole(s), the precise diffusion of angular momentum between stars, and the ejection of stars from a cluster orbiting a host galaxy Below we consider each topic in turn.
