摘要：

Models of spherically symmetric relativistic stellar clusters with anisotropic distribution functions in relativistic regime are described by using Maxwellian distribution function with energy cutoff. We consider distributions with different levels of anisotropy and discuss some general characteristics of the models. In addition, we analyze dynamic and thermodynamic stability of isotropic models still described by Maxwellian distribution function with energy cutoff and we find critical values of the onset of instability.
