Precession of inclined rings

Abstract
Differential precession due to the planet's quadrupole moment tends to destroy the alignment of particles in inclined rings. We propose that alignment is maintained by the self-gravity of the ring. This hypothesis predicts that δi/δɑ>0 across the ring. If δi/i0<(1, δe/e_0 <(1, ɑδi/δɑ<(1, and ɑδe/δɑ< 1, a further prediction is that δi/i_0 = δe/e_0. The ɑ and β rings of Uranus may be used to test these predictions.
