@article{79, author = {Yan-Fei Jiang and James Stone and Shane Davis}, title = {Radiation Magnetohydrodynamic Simulations of the Formation of Hot Accretion Disk Coronae}, abstract = {

A new mechanism to form a magnetic pressure supported, high temperature corona above the photosphere of an accretion disk is explored using three dimensional radiation magnetohydrodynamic (MHD) simulations. The thermal properties of the disk are calculated self-consistently by balancing radiative cooling through the surfaces of the disk with heating due to dissipation of turbulence driven by magneto-rotational instability (MRI). As has been noted in previous work, we find the dissipation rate per unit mass increases dramatically with...
