More Kronoseismology with Saturn's rings

Nicholson, P. D.; Hedman, M. M.

In a previous paper, we developed tools which allowed us to confirm that several of the waves in Saturn's rings were likely generated by resonances with fundamental sectoral normal modes inside Saturn itself. Here we use these same tools to examine eight additional waves that are probably generated by structures inside the planet. One of these wav…

A detailed numerical analysis of asymmetrical density distribution in Saturn's F ring during an encounter with Prometheus

Sutton, Phil J.; Kusmartsev, Feo V.

Saturn's rings, reminiscent of an early Solar system present a unique opportunity to investigate experimentally some mechanisms thought to be responsible for planet and planetesimal formation in protoplanetary discs. Here, we extended the comparison of our numerical models of Prometheus encountering the F ring employing non-interacting and interac…
