Abstract
Upper hybrid resonance emissions detected by theRadio and Plasma Wave Science (RPWS) instrument on theCassini spacecraft are used to obtain electron densities onfive equatorial orbits of Saturn at radial distances rangingfrom 3 to 9 saturnian radii (RS). The electron density profilesfor these orbits show a highly repeatable radial dependencebeyond 5 RS, decreasing with increasing radial distanceapproximately as (1/R)3.63. Inside 5 RS, the electron densityprofiles are highly variable. We show that these radialvariations are consistent with a centrifugally-drivenoutward transport of plasma from a source inside 5 RS.
