Scientific paper

The author considers self-similar solutions of two-dimensional axisymmetric steady accretion flows with angular momentum and arbitrary meridional velocities onto a Newtonian point mass, in which all nondimensionalized variables are functions of the latitude angle alone. Using a generalized α-model for the viscous stress, the author obtains solutions for radiation-pressure-dominated flows. These results shed critical new light on the structure of collimated jets driven by radiation pressure.
