Stellar Collisions and Black Hole Formation in Dense Star Clusters
Stephen McMillan, Simon Portegies Zwart
Close encounters and physical collisions between stars in young dense clusters may lead to the formation of very massive stars and black holes via runaway merging. We examine criti…
Simulating young star clusters with primordial binaries
Simon Portegies Zwart, Steve McMillan
We simulate a cluster of 144179 stars including 13107 primordial hard binaries (10% of the total number of single stars and binary centers of mass), using direct integration of the…
Life and Death of Young Dense Star Clusters near the Galactic Center
Simon Portegies Zwart, Stephen McMillan, Holger Baumgardt
We discuss the structural change and degree of mass segregation of young dense star clusters within about 100pc of the Galactic center. In our calculations, which are performed wit…
