Scientific paper

A one-armed spiral bending wave in Saturn's rings excited by Titan's -1:0 inner vertical resonance is one of the most prominent oscillatory features observed by Voyager 1. We study detailed dynamics of the particles inside the ring, and show that one of the main causes of the complete dissipation of the bending wave within a distance of ~85km from the resonance site could be as a result of the presence of a strong shear caused by radial velocity variation along the vertical direction. Assuming this to be the only source, Voyager data would suggest that if the surface density of matter is around 0.45gcm-2 and the amplitude of the bending wave is around 1200m, then the upper limit of total vertical thickness of the C ring near this resonance is around 40m.
