Abstract

In this brief review I sum up some recent progress in the area of stellar dynamics, focusing on the dynamics of self-bound stellar associations in isolation and in (approximate) equilibrium. The basics of stellar dynamics are first outlined and the importance of stellar evolution is stressed. Subsequently I argue that the evolution of multi-mass clusters in the point-mass approximation still holds clues to the dynamics of galaxy nuclei. I take a more personal standpoint when discussing the role of stellar evolution on the dynamics over relaxation time scales and draw from several recent models to underscore that a major step forward has been made in the coupling of stellar evolution and dynamics. I then briefly visit the issue of multiple stars and highlight some as yet unsolved problems.
