Abstract
We consider adiabatic accretion onto a black hole in the hydrodynamic approximation with zero
viscosity. For a slowly rotating black hole, the desired solution is a perturbation of a
spherically symmetric flow. We obtain an analytic solution for such a perturbation, and find the
correction to the accretion rate and the shape of the sonic surface. We take a similar
approach to the accretion of matter onto a slowly moving black hole. Our fundamental result is
that neither black hole rotation nor slow motion alters the essential nature of accretion. As
before, this result can be extended to supersonic velocities in a collisionless flow, with the shape
of the sonic surface and the accretion rate remaining virtually unchanged.
