Abstract
Abstract We study the steady axisymmetric Stokes flow of a viscous ideal gas past a gravitating sphere. We assume a simple form for the viscosity and thermal conductivity of the gas and take the flow as a small perturbation on the equilibrium state at rest. We use the method of separation of variables to reduce the basic equations to an ordinary fourth order differential equation. Drag coefficients, flow configurations and velocity distributions are given. In particular, the formation of a counter current region near the sphere is clarified for cases with strong gravity.
