A New Family of Models for Spherical Stellar Systems
Abstract
A new two-parametric family of mass distribution for spherical stellar systems is considered. It generalizes families by Kuzmin & Veltmann (1972) and by An & Evans (2006). Steady velocity dispersions are found for these models by solving an equation of hydrostatic equilibrium. Axisymmetric generalizations of the model are discussed.
