Radiato-thermal self-similar funnel jets

Abstract

ABSTRACT Steady axisymmetric two-dimensional flows driven by radiation and gas pressures in the conical funnel formed by the supercritical accretion disc are examined using the fully self-similar treatment. The effect of alpha-viscosity is also considered. The self-similar solutions are found to be classified into three types: successful outflows of hollow-conical or funnel-filled solutions, failed inflows, which are gravitationally bound, and unphysical cases, where the flow meets the singularity or the radiation energy density becomes negative.
