Origin of chaos in the Prometheus-Pandora system
@article{Goldreich2003OriginOC, title={Origin of chaos in the Prometheus-Pandora system}, author={P. Goldreich and N. Rappaport}, journal={Icarus}, year={2003}, volume={166}, pages={320-327} }
We demonstrate that the chaotic orbits of Prometheus and Pandora are due to interactions associated with the 121:118 mean motion resonance. Differential precession splits this resonance into a quartet of components equally spaced in frequency. Libration widths of the individual components exceed the splitting resulting in resonance overlap which causes the chaos. A single degree of freedom model captures the essential features of the chaotic dynamics. Mean motions of Prometheus and Pandora… CONTINUE READING
