Collapse and evolution of flattened star clusters.
BOILY C.M., CLARKE C.J. and MURRAY S.D.
Abstract (from CDS):
Following the phase of collapse, the clusters `bounce' and quickly establish a core–halo structure. The central region relaxes to near-spherical shape in a few crossing times; however, the envelope remains more elliptical, since two-body effects are reduced there. This ellipticity changes only slightly from its value at the time of the bounce over several crossing times of evolution. As cluster morphology at the bounce is deduced from adiabatic invariance, itself fixed by the initial conditions, we relate relaxed configurations to initial conditions through a simple analytic expression.
