| contents | This paper investigates the motion of a rotating test body in the Schwarzschild space-time. After reduction, this problem reduces to an analysis of a three-degree-of-freedom. Hamiltonian system whose desired trajectories lie on the invariant manifold described by the Tulczyjew condition. An analysis is made of the fixed points of this system which describe the motion of the test body in a circle. New circular orbits are found for which the orbital angular momentum is not parallel to the angular momentum of the test body. Using a Poincare map, bifurcations of periodic solutions are analyzed. |
