Stars and gaseous planets pulsate, and these oscillations provide a unique window into stellar and planetary interiors. Rapid rotation and magnetic fields can drastically alter the oscillations of fluid bodies, and the full effect of these physical processes remain an active area of research. I study oscillations in Saturn, which provides a fascinating example close to home; while Saturn's oscillations are too small-amplitude to be directly detected, they alter the surrounding gravitational field, driving density waves in it the planet's rings. The rapid migration of Saturn's moons also provides evidence of the dissipation of waves excited by tidal interactions.
