Abstract
It is demonstrated that, in the adiabatic approximation, nonequatorial circular orbits of particles in the Kerr metric (i.e., orbits of cons tant Boyer-Lindquist radius) remain circular under the influence of gr avitational radiation reaction. A brief discussion is given of conditi ons for breakdown of adiabaticity and of whether slightly noncircular orbits are stable against the growth of eccentricity.
