Gas Cloud Collisions and Stellar Cluster Formation
2011In this paper we present computer simulations of interstellar cloud collisions that for a given range of initial conditions could favor stellar cluster formation. We first construct a single spherical molecular hydrogen cloud with the Plummer radial density distribution with rigid rotation and an m = 2 density perturbation. The isolated cloud collapses

Stellar collisions and mergers in the cores of globular clusters
Physics Reports, 1999Abstract Rare and exotic stars are being discovered with Hubble Space Telescope (HST) observations in large numbers in the cores of globular clusters. Stellar collisions and/or mergers are likely responsible for many of these bizarre objects. I review the theoretical arguments which predict substantial populations of blue stragglers and cataclysmic ...

Cosmic collisions spin stellar corpses into gold
New Scientist, 2013A smash involving two neutron stars has spat out 10 moons' worth of gold, and may explain how the universe got its stock of the precious ...

Stellar Collisions within Very Wide Binaries
2014Although rare in the Milky Way, star-star collisions are predicted to occur within the dense cores of globular clusters, in evolving triple star systems, and possibly very near the Galactic center. It has recently been shown that very wide binary star systems can have their stellar orbits driven to very eccentric states by other passing field stars and
