Fabian Schneider (former PhD student in Bonn, now postdoctoral fellow in Oxford) simulated the evolution of the stellar mass function of coeval populations, such as star clusters.
He finds that mass loss and binary interaction reshapes the high end of the mass function within 0.3 dex of the turn off mass. He further discusses the implications for measuring the age of the cluster.
