TL;DR: Numerical simulations of the evolution and motion of stars within the clusters find that for MGG 11 dynamical friction leads to the massive stars sinking rapidly to the centre of the cluster, where they participate in a runaway collision.

TL;DR: The evolution of star clusters is studied using N-body simulations in which the evolution of single stars and binaries are taken self-consistently into account as mentioned in this paper, and initial conditions are chosen to represent relatively young Galactic open clusters, such as the Pleiades, Praesepe and the Hyades.

TL;DR: In this paper, the authors present conclusive observational evidence for a link between the number of close binaries observed in X-rays in a globular cluster and the stellar encounter rate of the cluster.

TL;DR: In this paper, the use of supercomputers in stellar dynamics calculations is discussed, including astrophysical problems and mathematical models; super/parallel computers; algorithms; many-body problem; and hydrodynamics.

TL;DR: In this paper, the discovery of an X-ray pulsar in the young, massive Galactic star cluster Westerlund 1 was reported, which indicates that it is a magnetar.
