Statistical Study on L-O Mode Saturn Kilometric Radiation
Original language description
Based on the 13 years-long observation of Saturn kilometric radiation (SKR) by the Cassini/Radio and Plasma Wave Science instrument, this study derives statistics for left-hand (L-O) mode SKR emissions. These emissions span a frequency range from below 10 kHz to approximately 1,000 kHz, with spectral flux densities ranging between 10(-24) and 10(-18) W/(m(2) Hz) consistent with, although fainter than, right-hand mode SKR. Predominantly observed within 20 Saturn radii, the occurrence rates of L-O mode SKR exhibit a preference below 20 degrees in latitude, and a local time asymmetry with a higher occurrence rate on the dayside. Occurrence maps indicate that low-frequency (<100 kHz) L-O mode SKR may be obstructed by the Enceladus plasma torus due to the higher electron density, while high-frequency (>100 kHz) emissions can pass through unhindered. Additionally, a substantial proportion of high-latitude L-O mode emissions exhibit strong elliptical polarization, contrasting with predominantly circular polarization observed at low latitudes.
