Description
We present an analytical study on a thick accretion disk model considering a charged fluid encircling a charge or non-charge black hole and endowed with an axisymmetric and stationary magnetic field. Our study is based on the Polish doughnut and provides an extension to this well-known model. Indeed, the effect of the electric and magnetic, and the gravitational fields are known on the accretion flow. The vertical and radial structures of the torus are influenced by these forces. Here our interest is to know how each of the interactions is involved in the equilibrium process as the gravity, the electric, and the magnetic force influence the shape and the density distribution of the fluid. We focus on orbiting structures in the equatorial plane, as single or double tori, on the polar axis, and structures above the equatorial plane as a levitating torus.
