Magnetohydrodynamic Turbulence in Accretion Discs

Magnetohydrodynamic Turbulence in Accretion Discs

We present results from numerical simulations of magneto-hydrodynamic turbulence in accretion discs. Our simulations show that the turbulent stresses that drive the accretion are less stratified than the matter; thus, the surface layers are more strongly heated than the interior of the disc.
