Abstract

Certain radial brightness variations in the outer Cassini division of Saturn's rings may be spiral density waves driven by Saturn's large moon Iapetus, in which case a value of ∼16 g cm^-2 for the surface density is calculated in the region where the waves are seen. The kinematic viscosity in the same region is ∼170 cm² s^-1 and the vertical scale height of the ring is estimated to be a maximum of ∼40 m.
