Transsonic Accretion Modes with Density Jumps

摘要

In this study, a class of steady-state solutions of the problem of matter incidence on a gravitating center (accretion), in which the matter jump through a sound barrier is performed at the discontinuity (density jump), is proposed. Substantiation of such solutions is given based on the theory of fast-slow systems. Certain partial solutions are presented as an example.
