Mechanisms of heating of the coronae around accretion disks
Abstract
It is shown that the de-excitation of convection elements in accretion disks considerably reduces convective energy transfer. The energy transferred by floating-up magnetic field tubes is also small. Therefore, radiative transfer is the main mechanism of energy transfer. It is concluded that hot coronae cannot exist around accretion disks.
