Hyperelliptic functions and motion in general relativity
Saskia Grunau, Jutta Kunz
Analysis of black hole spacetimes requires study of the motion of particles and light in these spacetimes. Here exact solutions of the geodesic equations are the means of choice. N…
The ISCO of charged particles in Reissner-Nordström, Kerr-Newman and Kerr-Sen spacetime
Kris Schroven, Saskia Grunau
In this article we study the innermost stable circular orbit (ISCO) of electrically charged particles in the electrically charged Reissner-Nordström spacetime, the Kerr-Newman spac…
Geodesic motion around a supersymmetric AdS5 black hole
Jens-Christian Drawer, Saskia Grunau
In this article the geodesic motion of test particles in the spacetime of a supersymmetric AdS black hole is studied. The equations of motion are derived and solved in terms of…
Topological black holes in mimetic gravity
Ahmad Sheykhi, Saskia Grunau
We construct some new classes of topological black hole solutions in the context of mimetic gravity. We study the uncharged and charged black holes, separately. In the absence of a…
Motion of charged particles around a scalarized black hole in Kaluza-Klein theory
Saskia Grunau, Matthias Kruse
In this article we study the geodesic motion of charged particles in the spacetime of an extremal rotating dyonic black hole in Kaluza-Klein theory. We derive the equations of moti…
Geodesic motion around traversable wormholes supported by a massless conformally-coupled scalar field
Felix Willenborg, Saskia Grunau, Burkhard Kleihaus +1
We consider a traversable wormhole solution of Einstein's gravity conformally coupled to a massless scalar field, a solution derived by Barcelo and Visser based on the JNWW spaceti…
