We describe a model that accounts for the complex morphology of spiraldensity waves raised in Saturn's rings by the co-orbital satellites, Janus andEpimetheus. Our model may be corroborated by future Cassini observations ofthese time-variable wave patterns.Comment: 9 pages, 5 figures; In press at Astrophysical Journal Letter
