Scientific paper

An analytic theory of dissipative and nondissipative shocks in rotating outflows is developed for both pseudo-Newtonian and Schwarzschild geometries, including the effects of the self-gravity of the surrounding massive disk. It is shown that the flow may have as many as five critical points when the angular momentum and the disk mass are sufficiently high. This leads to the possibility of multiple annular shocks within the flow. It is also shown that, for given initial flow parameters such as the angular momentum and the energy, there could be as many as 18 formal shock locations (out of which at most two are chosen in reality).
