Unravelling Temporal Variability in Saturn's Spiral Density Waves: Results and Predictions

Abstract

We describe a model that accounts for the complex morphology of spiral density waves raised in Saturn's rings by the co-orbital satellites, Janus and Epimetheus. Our model may be corroborated by future Cassini observations of these time-variable wave patterns.
