Abstract

A theoretical prediction for the formation of dust-Alfvénic Mach cones in Saturn's rings is made. It is explicitly shown that for typical dusty plasma parameters corresponding to Saturn's dense rings, Mach cones are only formed by dust-Alfvén waves which are found to be more prominent than any other longitudinal waves (e.g., dust-acoustic waves). The dust-Alfvénic Mach cones that we have reported here are expected to be observed in Saturn's rings by CASSINI, arriving at Saturn in 2004.
