A Possible Mechanism for Hot Corona Formation Around Black Holes
We consider a possible mechanism for hot corona formation in accretion disks around black holes. In the inner region of an accretion disk around a black hole, the orbits of particles depart from their Keplerian orbits because of General Relativity effects. The ellipticity of the orbit is very high and the orbital precession is considerable. Therefore violent collisions between the particles will occur in the disk and some of these particles will then escape from the disk to form a hot corona around the black hole. In this paper we investigate this effect and estimate properties of the corona formed through this mechanism.
