Exact relativistic models of thin disks around static black holes in a
magnetic field

Antonio C. Gutiérrez-Piñerez, Gonzalo García-Reyes, Guillermo A. González
The exact superposition of a central static black hole with surrounding thin disk in presence of a magnetic field is investigated. We consider two models of disks, one of infinite extension based on a Kuzmin-Chazy-Curzon metric and other finite based in the on the Morgan-Morgan metric. To explain the stability of the disks we also consider the matter of the disk made of two pressureless streams of counterrotating charged particles (counterrotating model) moving along electrogeodesic. Using the Rayleigh criterion we derivate for circular orbits the stability conditions of the particles of the streams.
