STATIONARY, AXISYMMETRIC BLACK HOLE MAGNETO SPHERES IN OBLATE SPHEROIDAL COORDINATES
In this paper, we simplify the equations of the Macdonald-Thome black hole magnetosphere. Our major assumption is that the 3-D electric and magnetic flux isosurfaces respectively form families of confocal oblate spheroids and hyperboloids. As a result, the magnetospheric equations are greatly simplified, and may provide a useful framework for instances when rigorous, theoretical approaches are not necessary.
