The star formation efficiency (SFE) of a star cluster is thought to be thecritical factor in determining if the cluster can survive for a significant(>50 Myr) time. There is an often quoted critical SFE of ~30 per cent for acluster to survive gas expulsion. I reiterate that the SFE is not the criticalfactor, rather it is the dynamical state of the stars (as measured by theirvirial ratio) immediately before gas expulsion that is the critical factor. Ifthe stars in a star cluster are born in an even slightly cold dynamical statethen the survivability of a cluster can be greatly increased.

The effect of the dynamical state of clusters on gas expulsion and infant mortality
