We will develop a consistent numerical framework for modeling stellar collisions, and to further evolve these collision products with a robust stellar evolution code. Collisions between stars are common in dense star clusters, where they can result in blue stragglers and very massive stars. These merger products are important tracers of the dynamical processes inside dense clusters. We request financial support for two PhD students: one will work on the hydrodynamics of stellar collisions and the other on the stellar evolution of collision remnants. The work will result in two routines that will be implemented in existing N-body solvers to study the dynamical evolution of dense star clusters.
