Charged Annular Disks and Reissner-Nordström Type Black Holes from Extremal Dust

F. D. Lora-Clavijo, P. A. Ospina-Henao, J. F. Pedraza

We present the first analytical superposition of a charged black hole with an annular disk of extremal dust. In order to obtain the solutions, we first solve the Einstein-Maxwell f…
