Abstract
An increasing number of young star clusters are being observed to have
significant internal rotation. In this respect, it is crucial to
understand the role of angular momentum during the initial stages of
star cluster dynamical evolution. Driven by these motivations, we
explored the dynamics of the dissipationless collapse in the presence of
non-vanishing initial angular momentum. We present here the preliminary
results of an extended survey of N-body simulations, designed to
investigate the early dynamical evolution of stellar systems with
different amounts of total angular momentum, initially characterized by
uniform density and solid body rotation. The structural and kinematical
properties of the systems resulting from such "violent relaxation"
scenario will be described, with emphasis on the dynamical interplay
between internal rotation and pressure support.
