| Abstract: |
Motion of a test particle in a gravitational field is considered. The steady-state rotationally symmetric model consists of a razor-thin disk and a halo. We extend the analytical method of constructing invariant curves by Tohline & Voyages (2001) to our model which is somewhat more general. The situation depends on a partition of model mass between the disk and the halo.
The periodic polar orbit obtained earlier is mentioned. Spatial trajectories have been calculated as well. Orbits are piecewise plane, so angular momentum changes discontinually and stochastically while crossing the disk. The distribution of angular momenta is considered in dependence on energy. |
