Abstract
The number of gravitons emitted during binary inspiral is found to be remarkably close to (though slightly larger than) the radiated angular momentum in units of 2ℏ. This (∼1%) closeness holds both for an infinitesimal change in the eccentricity, and for the total graviton number emitted during inspiral from a large eccentricity initial orbit down to negligible final eccentricity.
