Abstract
A kinetic equation for a jet stream consisting of identical, partially inelastic grains in neighbouring orbits around a central gravitating body is derived and given a preliminary discussion. No nonsingular equilibrium state exists for the jet stream configuration. The Boyle-Mariotte ideal gas law does not apply. The effect of hard, partially inelastic collisions is to decrease the kinetic temperature of the stream, thereby leading to a lining-up of the orbits of the individual grains with a subsequent reduction in the importance of collisions on the dynamics of the stream.
