Abstract: In this work, we investigate the dynamical evolution of spherical self-gravitating systems under their own gravity with N-body simulations. For this purpose, we study the evolution of the generalized virialization relations, and particularly focus on… read more here.

Abstract: In this study, an $N$-body simulation code was developed for self-gravitating systems with a limited first-order post-Newtonian approximation. The code was applied to a special case in which the system consists of one massive object… read more here.
