represented by two anisotropic Maxwellian distributed species, H + and a water group ion, W + . Saturn’s magnetospheric plasma is shown to subcorotate by 15–30% below rigid corotation within this region, with a minimum in fractional lag between 7 and 9 RS. There is a suggestion of a small radial outflow, but the selection of data for this study precluded the inclusion of interchange injection events. Ion densities are in excellent agreement with the Cassini plasma wave instrument, giving… Expand
Survey of thermal plasma ions in Saturn's magnetosphere utilizing a forward model
The Cassini Plasma Spectrometer instrument gathered thermal ion data at Saturn from 2004 to 2012, predominantly observing water group ions and protons. Plasma parameters, with uncertainties, forExpand
Survey of ion plasma parameters in Saturn's magnetosphere
[1] A survey of the bulk plasma ion properties observed by the Cassini Plasma Spectrometer instrument over roughly the first 4.5 years of its mission in orbit around Saturn is presented. The momentsExpand
Thermal ion flow in Saturn's inner magnetosphere measured by the Cassini plasma spectrometer: A signature of the Enceladus torus?
For the middle and outer magnetosphere of Saturn (>5.5 R S ), Cassini plasma spectrometer ion counting data provides thermal ion moments by assuming Maxwellian phase space density distributions forExpand
Kelvin-Helmholtz instability at Saturn's magnetopause: Cassini ion data analysis
[1] On 13 December 2004 Cassini, on approach to Saturn from the dawn flank, crossed the magnetopause multiple times. During these events the plasma spectrometer had a good field of view of both theExpand
A diffusive equilibrium model for the plasma density in Saturn's magnetosphere
[1] Electron density measurements have been obtained by the Cassini Radio and Plasma Wave Science (RPWS) instrument for more than 50 passes through Saturn's inner magnetosphere from 30 June 2004 toExpand
Periodicity in Saturn's magnetosphere: Plasma cam
[1] Plasma ion data from the Cassini Plasma Spectrometer (CAPS) are examined for all orbits from October 25, 2004 through Dec. 26, 2007. To eliminate effects of incomplete angular coverage, data areExpand
Nature of the ring current in Saturn's dayside magnetosphere
[1] We employ magnetic field and plasma particle data from two equatorial passes of the Cassini spacecraft spanning the radial range between ∼3 and ∼20 RS to investigate the nature of the ringExpand
Plasma in Saturn's Nightside Magnetosphere and the Implications for Global Circulation
We present a bulk ion flow map from the nightside, equatorial region of Saturn's magnetosphere derived from the Cassini CAPS ion mass spectrometer data. The map clearly demonstrates the dominance ofExpand
Distribution of water-group ion cyclotron waves in Saturn’s magnetosphere
The water-group ion cyclotron waves (ICWs) in Saturn’s magnetosphere were studied using the magnetic field data provided by the MAG magnetometer on board the Cassini satellite. The period fromExpand
Rate of radial transport of plasma in Saturn's inner magnetosphere
[1] In the inner part of a rapidly rotating magnetosphere such as that of Saturn, the major observable signature of radial plasma convection is a series of longitudinally localized injections andExpand


Preliminary results on Saturn's inner plasmasphere as observed by Cassini: Comparison with Voyager

A model for the azimuthal plasma velocity in Saturn's magnetosphere
[1] We present a model for Saturn's magnetospheric azimuthal plasma velocities measured by Voyager 1 and 2. The observed velocity profiles deviate from full corotation and show two dips slightlyExpand
Evidence for rotationally-driven plasma transport in Saturn's magnetosphere
[1] Radial convective transport of plasma in a rotation-dominated magnetosphere implies alternating longitudinal sectors of cooler, denser plasma moving outward and hotter, more tenuous plasma movingExpand
A plasma density model for Saturn based on Voyager observations
The density, temperature, and velocity of plasma in the inner magnetosphere (L<12) of Saturn are well determined from observations by the Voyager plasma science experiment. We combine the ion andExpand
Statistical analysis of injection/dispersion events in Saturn's inner magnetosphere
[1] In the inner magnetosphere of a rapidly rotating planet such as Jupiter and Saturn, radial transport of plasma mainly comprises hot, tenuous plasma moving inward and cold, denser plasma movingExpand
