Are there moonlets near the Uranian alpha and beta rings?
R. O. Chancia, M. M. Hedman
The Voyager 2 Radio Science Subsystem occultations of the Uranian alpha and beta rings exhibit quasi-periodic optical depth variations with radial wavelengths that vary with longit…
A curious ringlet that shares Prometheus' orbit but precesses like the F ring
M. M. Hedman, B. J. Carter
Images obtained by the Cassini spacecraft of the region just beyond Saturn's main rings reveal a previously unreported narrow and dusty ringlet that has dynamical connections with…
