Core radii of globular clusters in the Large and Small Magellanic Clouds show an increasing trend with age. We propose that this trend is a dynamical effect resulting from the accumulation of massive stars and stellar-mass black holes at the cluster

Instability of the Gravitational N-Body Problem in the Large-N Limit

Autor: Hemsendorf, Marc, Merritt, David

Publikováno v: Astrophys.J. 580 (2002) 606-609

We use a systolic N-body algorithm to evaluate the linear stability of the gravitational N-body problem for N up to 1.3 x 10^5, two orders of magnitude greater than in previous experiments. For the first time, a clear ~ln N-dependence of the perturba

Collisional dynamics around binary black holes in galactic centers

Autor: Hemsendorf, Marc, Sigurdsson, Steinn, Spurzem, Rainer

Publikováno v: Astrophys.J. 581 (2002) 1256-1270

We follow the sinking of two massive black holes in a spherical stellar system where the black holes become bound under the influence of dynamical friction. Once bound, the binary hardens by three-body encounters with surrounding stars. We find that
