Stationary Ring–Black Hole Systems — •David Petroff¹ and Marcus Ansorg² — ¹Theoretisch-Physikalisches Institut, FSU Jena — ²Max-Planck-Institut für Gravitationsphysik (AEI), Golm

An axially symmetric, stationary spacetime containing a Black Hole surrounded by a ring of matter is constructed numerically. Because of the extremely high accuracy of the numerical solutions obtained, it is possible to solve for critical configurations and study subtle properties of these solutions that would otherwise be difficult to resolve. After a brief discussion of the numerical methods, these subtleties will be illuminated.
