Motion around gravitating monopoles — •Valeria Kagramanova1, Jutta Kunz1, and Claus Lämmerzahl21Institut für Physik, Univ. Oldenburg — 2ZARM, Univ. Bremen

Magnetic monopoles arise as globally regular solutions of Einstein-Yang-Mills-Higgs theory. The singly charged magnetic monopole is static and spherically symmetric. Magnetic monopoles with higher charges possess only axial symmetry or discrete symmetries. Beside focussing primarily on properties of the metric it is certainly of interest to characterize solutions of gravitational field equations in terms of the properties of the possible test particle motions, since only matter and light give observational insight into a given gravitational field. In the case of magnetic monopoles, the particle motion is given by an effective potential which depends on the angular momentum as well as on the energy of the particle. We obtain scattering states, various classes of bound states as well as limiting states. Characteristic features of the orbits like scattering angles and periods of the motion, both related to the coupling strength, are obtained.
