Dynamical constraints on the origin of multiple stellar populations in globular clusters

Abstract: We have carried out a large grid of N -body simulations in order to investigate if massloss as a result of primordial gas expulsion can be responsible for the large fraction of second generation stars in globular clusters (GCs) with multiple stellar populations (MSPs). Our clusters start with two stellar populations in which 10% of all stars are second generation stars. We simulate clusters with different initial masses, different ratios of the half-mass radius of first to second generation stars, different pr… Show more
