Abstract

The latitudinal motion of free test particles outwards from central regionsin the Kerr geometry is investigated. As compared with particles with parabolic energies, particles with hyperbolic energies escape closer to the rotation axis, while slower particles tend to fall towards the equatorial plane. The effect is not large in the case of black holes, but it is significant for naked singularities. In a region still closer to the center, the repulsive character of the field near the rotation axis and near the disk spanning the ring singularity gives particles outward accelerations and collimates the particles along the rotation axis.
