Influence of magnetic field and charge black hole on equilibrium of thick accretion disk — •Audrey Trova — Zarm, University of Bremen, Germany

We are presenting an analytical model of a thick accretion disk modeled by a charged fluid encircling a charged black hole and endowed in an asymptotically magnetic field. Both electric and magnetic fields are known to influence the accretion flow. Our study is based on the Polish doughnut model and provides an extension of this well-known model. Here our interest is to know how each of the interactions involved in the equilibrium process as the gravity, the electric force, and the magnetic force, are influencing the shape and the density distribution of the fluid. We are focusing on orbiting structures in the equatorial plane, as single or double tori, and structures above the equatorial plane as levitating torus which can be relevant for coronal plasma.
