Early dynamics and violent relaxation of multi-mass rotating star
  clusters
  We present the results of a study aimed at exploring, by means of N-body
simulations, the evolution of rotating multi-mass star clusters during the
violent relaxation phase, in the presence of a weak external tidal field. We
study the implications of the initial rotation and the presence of a mass
spectrum for the violent relaxation dynamics and the final properties of the
equilibria emerging at the end of this stage. Our simulations show a clear
manifestation of the evolution towards spatial mass segregation and evolution
towards energy equipartition during and at the end of the violent relaxation
phase. We study the final rotational kinematics and show that massive stars
tend to rotate more rapidly than low-mass stars around the axis of cluster
rotation. Our analysis also reveals that during the violent relaxation phase,
massive stars tend to preferentially segregate into orbits with angular
momentum aligned with the cluster's angular momentum, an effect previously
found in the context of the long-term evolution of star clusters driven by
two-body relaxation.
