Dynamical Evolution of Globular Clusters with a Dark Matter Halo
Jihye Shin (Kyung Hee Univ.)

If globular clusters initially had a dark matter halo around them, their early dynamical evolution could be different from the case without the halo, which has been the usual assumptions made for the studies of the dynamical evolution of globular clusters. With the most advanced 2-dimensinoal Fokker-Planck models, we study the effects of the presence of the dark matter halo on the dynamical evolution and the present mass-to-light ratios of globular cluster systems. We also consider the early evaporation of the remnant gas material.
