| Abstract: |
The relaxation time estimates in the spaces of the several star motion parameters were obtained for a number of the open cluster models. The relaxation time differences in these spaces are the greater for the more nonstationary cluster models. During the cluster models evolution their relaxation times increase in all considered spaces. During the violent relaxation the stars occupy all accessible for them regions at first in the space of the velocities moduli and then in the space of the distances from the cluster center. The tendency to the weakening of the dependence of the coarse grained phase density of cluster under the influence of small initial perturbations of the phase coordinates of stars in the cluster models for the time moments greater than the violent relaxation time and the two-body relaxation time was displayed. |
