Threedimensional models for the distribution of mass in galaxies.
Abstract
From Toomre's (1963) disk models of galaxies, other convenient pairs of functions are generalized to represent the axisymmetric potential and density of models in which the mass is no longer confined to a single plane. These pairs of functions include some that vary continuously from Kuzmin's (1956) thindisk model to Plummer's (1911) spherical model for globular clusters. The models are free from singularities and involve functions that are quite explicit and elementary. Even without superposing any of them, the present density laws seem to simulate remarkably well the stratifications of mass both in the central bulges and in the disk parts of real galaxies.
