摘要：

We construct a simple dynamical model of the massive globular cluster omega Cen. The model includes simple treatments of dynamical evolution in a galactic tide, and evolution of single stars. Binary stars and rotation are neglected. The model approximately fits observational data on the surface brightness profile, the profile of radial velocity dispersion, and the main sequence mass function at two radii.
