[33.01] Kinematics of Non-Circular Features in Saturn's Rings

A. S. Bosh (Boston Univ./Lowell Obs.)

Recent stellar occultation observations have allowed the refinement of Saturn's pole position and investigation of the kinematics of non-circular features in Saturn's rings. In particular, the 1995 occultation of GSC5249-01240 occurred near the time of the ring-plane crossing and therefore was unusually sensitive to any out-of-plane behavior of the rings. These data have already allowed the identification of the F ring's inclination (Bosh et al. 2002, Icarus 157, 57). Using these data as well as other available occultation data sets, we present current models of several non-circular ring features, including the Titan and Huygens ringlets. This work is supported by HST grant AR-8761.
