Geometrically thick fluid tori parametrisations — •Pavel Jefremov and Vojtěch Witzany — ZARM, Universität Bremen

In this talk I investigate various new solution for the geometrically thick toroidal perfect fluid configurations orbiting a stationary and axisymmetric black hole. These solutions are constructed by demanding that the velocity field of the orbiting fluid be expressed analytically through the parameter(s) of the resulting configuration. The well-known analytical solutions such as Polish Doughnuts with constant angular momentum and the Fishbone-Moncrief tori are then recovered as special cases of the resulting more general family of solutions.
