Weakly dissipative plasma equilibria in Kerr geometry

Axisymmetric neutral plasma equilibria of electrons and ions near black holes can be constructed from solutions of ideal multifluid equations; the solutions for the ions are obtained from a modified Grad–Shafranov code for the stream function. The density and the flux functions are determined self-consistently from the normalization of the Eulerian four-velocity and a simple dissipation model for the ions, respectively. Solutions with moderate or vanishing toroidal velocity exist, but the black hole receives matter only in nonequilibrium situations.
