Gravity Waves & Gravitomotive Force: Is Rotation Possible?

[QUOTE="pervect, post: 5456339, member: 14402"] I'd say yes, offhand, that there shouldn't be any GW emission in the directions in which the components of the quadrupole moment is constant. For instance, if the rotation is in the xy plane, and z is constant so that the integral of ##z^2 dm## is constant, I wouldn't expect any gravitational radiation in the z direction. But I don't have a rigorous proof, or a reference that says exactly this (Wiki and by memory several textbooks do say that you need a nonzero quadrupole moment to have gravitational radiation at all, but this doesn't quite say anything about the direction of the radiation).
