Collisionless analogs of Riemann ellipsoids - Self-consistent model of an ellipsoid with 'oblique' rotation
Abstract
The motion of a particle in a model ellipsoidal stellar system with no equatorial plane of symmetry perpendicular to the rotation axis (similar in some respects to the Riemann fluid ellipsoids studied by Chandrasekhar, 1969) is investigated analytically. The equations of motion and a singular line are defined, and a general solution is obtained which permits determination of the conditions under which a particle reaches the ellipsoidal boundary surface. A number of special cases with velocity dispersion and the transitions to the limiting cases of the Freeman (1966) ellipsoid and adjoint ellipsoids (without velocity dispersion) are considered.
