  We describe stationary and axisymmetric gas configurations surrounding black
holes. They consist of a collisionless relativistic kinetic gas of identical
massive particles following bound orbits in a Schwarzschild exterior spacetime
and are modeled by a one-particle distribution function which is the product of
a function of the energy and a function of the orbital inclination associated
with the particle's trajectory. The morphology of the resulting configuration
is analyzed.
