Indeed.

A reasonable treatment of the evolution of gravitationally bound
clusters of stars is online at Caltech minus a few diagrams:

I'm no expert in this field, but I think that it might be a bit more
complicated. Look up "fast rotator" and "slow rotator" in the context
of elliptical galaxies. This might be a place to start:
