Masses of satellites and oblateness parameters of Saturn.
Abstract
The masses of Enceladus and Dione are recomputed by a correct theory and found to be ten percent smaller than those previously derived. Accurate expressions for solar perturbations and perturbations in Titan's orbit due to Iapetus are developed and used in the determination of the mass of Iapetus. Oblateness parameters and the mass of Rhea are derived from seven observed secular motions for six satellites. The semimajor axis is computed for each satellite and is found to differ appreciably from that adopted in almanacs.
