The Distribution of Collisionally Induced Blue Stragglers in the Color-Magnitude Diagram

A primary production mechanism for blue stragglers in globular clusters is thought to be collisionally induced mergers, perhaps mediated by dynamical encounters involving binary stars. We model the formation and evolution of such blue stragglers and produce theoretical distributions of them in the color-magnitude diagram. We use a crude representation of cluster dynamics and detailed binary-single star encounter simulations to produce cross …
