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…
Black Holes in Massive Star Clusters
Steve McMillan, Holger Baumgardt, Simon Portegies Zwart +2
Close encounters and physical collisions between stars in young dense clusters can result in new channels for stellar evolution, and may lead to the formation of very massive stars…
The gravitational wave signature of young and dense star clusters
Simon Portegies Zwart
Young star clusters are often born with such high stellar densities that stellar collisions play an important role in their further evolution. In such environments the same star ma…
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…
Dynamics of Intermediate Mass Black Holes in Star Clusters
Holger Baumgardt, Simon Portegies Zwart, Steve McMillan +2
We have followed the evolution of multi-mass star clusters containing massive central black holes by N-body simulations on the GRAPE6 computers of Tokyo University. We find a stron…
