A New Family of Models for Spherical Stellar Systems

Variable Stars, The Galactic Halo And Galaxy Formation, C. Sterken, N. Samus and L. Szabados (Eds.) 2010, pp.149-151 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.
