Abstract
At low densities, when radiation of an accreting gas is dynamically unimportant, quasi-spherical non-radiative accretion flow is formed around a compact object. We show that the density of the flow is n\propto r^{-1/2}. The gas compression is much weaker than the standard Bondi's, n\propto r^{-3/2}, because most of the gas does not reach the compact object. It can either circulate indefinitely long or it can be launched to infinity.
