Accretion Disk Models with Self-Consistent Advective Cooling and Heating

Abstract

We present solutions to the accretion disk structure equations in which advective cooling is accounted for in a self-consistent way. It is shown that for high rates of accretion, above a critical value, when without advection there are no solutions extending continuously from large to small radii, there exist global solutions with self-consistent advective cooling. These solutions are quite different fromthose solutions obtained earlier by other authors, where advective cooling was not treated self-consistently.
