Apparent age spreads in clusters and the role of stellar rotation

We use the Geneva syclist isochrone models that include the effects of stellar rotation to investigate the role that rotation has on the resulting colour–magnitude diagram of young and intermediate age clusters. We find that if a distribution of rotation velocities exists within the clusters, rotati...
