A dynamical origin for early mass segregation in young star clusters
Stephen L. W. McMillan, Enrico Vesperini, Simon F. Portegies Zwart
Some young star clusters show a degree of mass segregation that is inconsistent with the effects of standard two-body relaxation from an initially unsegregated system without subst…
Star Cluster Ecology: VII The evolution of young dense star clusters containing primordial binaries
Simon Portegies Zwart, Steve McMillan, Jun Makino
We study the first 100Myr of the evolution of isolated star clusters initially containing 144179 stars, including 13107 (10%) primordial hard binaries. Our calculations include the…
The formation of higher-order hierarchical systems in star clusters
Jelle van den Berk, Simon Portegies Zwart, Steve McMillan
We simulate open clusters containing up to 182 stars initially in the form of singles, binaries and triples. Due to the high interaction rate a large number of stable quadruples, q…
