Statistics of Small-N Simulations
Douglas C. Heggie
We first review the reasons for carrying out statistical analysis of results from large numbers of N-body simulations, including a summary of previous work. Then we describe some r…
Dark Matter in Globular Clusters
Douglas C. Heggie, Piet Hut
We first review reasons why dark matter is an interesting issue in connection with star clusters. Next we consider to what extent the presence of dark matter is consistent with the…
Statistics of N-Body Simulations. III. Unequal Masses
Mirek Giersz, Douglas C. Heggie
We describe results from large numbers of -body simulations containing from to stars each. The distribution of stellar masses is a power law, and the systems are is…
The Effect of Encounters on the Eccentricity of Binaries in Clusters
Douglas C. Heggie, Frederic A. Rasio
We derive analytical expressions for the change in the orbital eccentricity of a binary following a distant encounter with a third star on a hyperbolic or parabolic orbit. To estab…
THE ORBITAL ECCENTRICITIES OF BINARY MILLISECOND PULSARS IN GLOBULAR CLUSTERS
Frederic A. Rasio, Douglas C. Heggie
Low-mass binary millisecond pulsars (LMBPs) are born with very small orbital eccentricities, typically of order --. In globular clusters, however, higher e…
