A new procedure is given for deriving the distribution of the orbital planes of binaries in clusters, based upon the statistics of the observed mass functions. Tables are provided for applications of the method. The procedure is applied to IC 4665 and an average inclination of 45 and a small dispersion of the inclinations is found.

On the dynamics of open clusters
Astronomy Reports, 2011The kinematics of stars in open-cluster models are investigated. The central regions of these model clusters are fairly “cool, ” leading to gravitational instability in the cluster cores. A temporary virilization is observed in the model clusters, during which an appreciable fraction of the fluctuation energy of the cluster is temporarily transformed ...
