The Role of Electric Charge in Relativistic Accretion onto Compact Objects — •Kris Schroven — Universität Bremen, Bremen, Germany

The role of electric charge in relativistic accretion onto compact objects is discussed by means of analytic models. Many high-luminosity phenomena in the observed universe can be traced back to accretion processes, in which electromagnetic fields play an important role. These fields are either produced within the accreted matter or they enter the stage as external fields like interstellar magnetic fields or fields, produced by the accreting object.

Two analytic models are applied to examine the effects of a realistically small electric BH charge and the effects of a charge distribution in the accreted matter onto the accretion process and accretion disc structure.
