Plasma Wave Observations with Cassini at Saturn

Since the Cassini spacecraft arrived at Saturn in 2004, the Radio and Plasma Wave Science (RPWS) -investigation has detected a variety of radio and plasma waves in the magnetosphere of Saturn, including whistler mode chorus and hiss, lightning-produced whistlers, high latitude auroral hiss, electrostatic electron cyclotron harmonic (ECH), upper hybrid resonance (UHR) and Langmuir wave emissions, Z-and O-mode narrowband emissions, and Saturn kilometric radiation (SKR). A number of these emissions often exhibit intensity modulations with periods ranging from about 10.6 to 10.8 hours. Plasma waves have also been detected in association with the Saturnian moons, including Enceladus and Rhea. We will review these observations and discuss the properties of the various waves.
