  • We present new Fokker-Planck models of the evolution of globular clusters, including gravitational tidal shocks. We extend our calculations beyond the core collapse by adopting three-body binary heating. EUects of the shocks are included by adding the tidal shock diUusion coefficients to the ordinary Fokker-Planck equation: the —rst-order heating term, S*ET, and the second-order energy dispersion term, S*E2T. As an example, we investigate the evolution of models for the globular cluster NGC… CONTINUE READING
