Relativistic astrophysics - in the strict sense of the words - deals with stars and other cosmic objects that can only be described by means of Einstein's theory of general relativity. Such objects are neutron stars and black holes.
Our goal is to achieve a better understanding of the basic properties of neutron stars and black holes using analytical and numerical solutions to Einstein's field equations. From a mathematical point of view, we are dealing with methods for rigorously solving initial and boundary value problems of the Einstein-Maxwell equations.
A particular emphasis of our research is on the modelling of equilibrium configurations of rotating fluid bodies and their quasi-stationary transition to rotating black holes, see "Relativistic Figures of Equilibrium".
