Infant mortality in the hierarchical merging scenario: dependence on gas expulsion time-scales

We examine the effects of gas expulsion on initially substructured and out-of-equilibrium star clusters. We perform N-body simulations of the evolution of star clusters in a static background potential before adjusting that potential to model gas expulsion. We investigate the impact of varying the r...
