We use a heat conduction prescription based on the Kramers opacity law which allows the depth of the convection zone to dynamically adapt to changes in …

WebIn the alpha models (Shakura & Sunyaev 1973) for gas-pressure dominated discs, is equal to 5/3 for a Thomson opacity law and 10/7 for a Kramers opacity law. Stability therefore requires to exceed 8/3 or 41/21, respectively. Although bulk viscosity is not often discussed in the context of alpha models, ...
