Abstract
Gas dynamic features of slowly rotating axially symmetric gas accretion on to a gravitating centre are investigated. The process of flow restructuring is studied as the angular velocity of accreting matter approaches the Keplerian angular velocity. For spherically symmetric accretion the conditions are found of the existance of a steady-state state supersonic solution for various extertnal boundary conditions. A numerical study is performed on the basis of the Lax-Friedrichs-type second-order numerical scheme with an implicit approximation of the term in the Euler equations.Keywords
