Analytic solutions of the geodesic equation for Einstein-Maxwell-dilaton-axion black holes (1509.03135v2)
Published 10 Sep 2015 in gr-qc
Abstract: In this article we study the geodesic motion of test particles and light in the Einstein-Maxwell-Dilaton-Axion black hole spacetime. We derive the equations of motion and present their solutions in terms of the Weierstra{\ss} $\wp$-, $\sigma$- and $\zeta$-functions. With the help of parametric diagrams and effective potentials we analyze the geodesic motion and give a list of all possible orbit types.
