Abstract / Description of output
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.
