Evidence for the strong effect of gas removal on the internal dynamics of young stellar clusters.
BASTIAN N. and GOODWIN S.P.
Abstract (from CDS):
That these clusters are not in equilibrium can explain the discrepant mass-to-light ratios observed in many young clusters with respect to simple stellar population models without resorting to non-standard initial stellar mass functions as claimed for M82-F and NGC 1705-1. We also discuss the effect of rapid gas removal on the complete disruption of a large fraction of young massive clusters (`infant mortality'). Finally, we note that even bound clusters may lose >50 per cent of their initial stellar mass as a result of rapid gas loss (`infant weight-loss').
