MODEST Working Group 4:
Stellar Collisions

Collisions between stars in dense stellar systems are thought to produce tell-tale `stellar exotica,' i.e. stars with a peculiar structure and evolution, like blue stragglers or very massive stars. They also influence the overall dynamics by changing the number, masses and orbits of stars. In galactic nuclei, collisional mass loss contributes to the feeding of massive black holes. Our goals are to understand and describe stellar collisions through hydrodynamical simulations and (semi)analytical calculations and to develop numerical methods to incorporate that knowledge into stellar dynamical models.
