Relativistic dust accretion of charged particles in Kerr-Newman spacetime

Understand

We describe a new analytical model for the accretion of particles from a rotating and charged spherical shell of dilute collisionless plasma onto a rotating and charged black hole.

• By assuming a continuous injection of particles at the spherical shell and by treating the black hole and a featureless accretion disc located in the equatorial plane as passive sinks of particles we build a stationary accretion model.
• This may then serve as a toy model for plasma feeding an accretion disc around a charged and rotating black hole.
• Therefore, our new model is a direct generalization of the analytical accretion model introduced by E.
