Geodesic equation for U(1)^2 dyonic rotating black holes. |
|
Abstract |
In this talk we present the equations of motion of test particles and light of the six parameter U(1)^2 dyonic rotating black hole family and its solutions. One special feature of this spacetime is the 2-dimensional curvature singularity, which shape varies from ring singularities to toroidal like structures. The equations of motion can be derived from the Hamilton-Jacobi equation and are solved in terms of derivatives of the hyperelliptic Kleinian sigma-function. We use parametric diagrams and effective potentials to characerize the radial and latitudinal motion and present a list of possible orbit types. |
