General spherical anisotropic Jeans models of stellar kinematics: including proper motions and radial velocities

Abstract

Cappellari (2008) presented a flexible and efficient method to model the stellar kinematics of anisotropic axisymmetric and spherical stellar systems. The spherical formalism could be used to model the line-of-sight velocity second moments allowing for essentially arbitrary radial variation in the anisotropy and general luminous and total density profiles. Here we generalize the spherical formalism by providing the expressions for all three components of the projected second moments, including the two proper motion components. A reference implementation is now included in the public JAM package available at http://purl.org/cappellari/softwareComment: 3 pages, 2 figures, LaTeX. Not submitted anywhere but here. Software implementing the update to the JAM method described in this paper is available at http://purl.org/cappellari/softwar
