Cassini UVIS observations of the Io plasma torus. I. Initial results

Cassini UVIS Observations of the Io Plasma Torus. III. Observations of Temporal and Azimuthal Variability

Io plasma torus ion composition: Voyager, Galileo, and Cassini

The Io torus produces ultraviolet emissions diagnostic of plasma conditions. We revisit data sets obtained by the Voyager 1, Galileo, and Cassini missions at Jupiter. With the latest version (8.0) of…

Radial Variations in the Io Plasma Torus during the Cassini Era

[1] A radial scan through the midnight sector of the Io plasma torus was made by the Cassini Ultraviolet Imaging Spectrograph on 14 January 2001, shortly after closest approach to Jupiter. From these…

Identification of Extreme Ultraviolet Emission Lines of the Io Plasma Torus Observed by Hisaki/EXCEED

The sulfur and oxygen ions in the Io plasma torus (IPT), which is located at a distance of ~6 RJ from Jupiter, emit light in various wavelength regions. In particular, radiative cooling in the…

Two Years of Observations of the Io Plasma Torus by Juno Radio Occultations: Results From Perijoves 1 to 15

The Io plasma torus is the primary source for plasma in Jupiter’s magnetosphere. Observations of fundamental properties of the torus place valuable constraints on how the Io plasma torus behaves. Yet…

Radial variation of sulfur and oxygen ions in the Io plasma torus as deduced from remote observations by Hisaki

The Io plasma torus, situated in the Jovian inner magnetosphere (6–8 Jovian radii from the planet) is filled with heavy ions and electrons, a large part of which are derived from Io's volcanos. The…

Variations in the Density Distribution of the Io Plasma Torus as Seen by Radio Occultations on Juno Perijoves 3, 6, and 8

The atmosphere of the Jovian satellite Io is constantly being lost to the surrounding magnetosphere of Jupiter. The material is ionized and then distributed by Jupiter's magnetic field into a torus…

Modeling Temporal Variability of Plasma Conditions in the Io Torus during the Cassini Era

[1] Observations of ultraviolet (UV) emissions from the major ion species (S+, S++, S+++, O+, O++) of the Io plasma torus made during the Cassini flyby (October 2000 to March 2001) have revealed…

The Far-Ultraviolet Spectrum of the Io Plasma Torus

The spectrum of the Io plasma torus in the range 905-1187 Å was recorded at 0.26 Å resolution by the Far Ultraviolet Spectroscopic Explorer (FUSE) on 2001 January 14. Five orbits of data were…

Empirical model of the Io plasma torus: Voyager measurements

We present a description of plasma conditions in the Io plasma torus, between 5 and 10 RJ, based on Voyager 1 observations obtained in March 1979. The model includes updated analyses of Plasma…

Observations of plasmas in the Io torus with the Galileo spacecraft

On December 7, 1995, the Galileo spacecraft passed through the Io torus near the magnetic equatorial plane of Jupiter. High– resolution measurements of positive ions and electrons in the…

A comparison of the Voyager 1 ultraviolet spectrometer and plasma science measurements of the Io plasma torus

We have developed a sophisticated package (Colorado Io Torus Emissions Package, or CITEP) to simulate emissions from the Io plasma torus, and have used it to examine the consistency of Voyager in…

High‐resolution spectroscopy of the Io plasma torus during the Galileo mission

We present Doppler-resolved spectra of the Io plasma torus (IPT) acquired in September 1997 and October 1999. The spectra are used to demonstrate the decrease in T⊥(S+) with increasing radial…

The latitudinal dependence of ion temperature in the Io plasma torus

A set of ground‐based spectroscopic observations of the [SII] 6716 Å, 6731 Å emission from the Io plasma torus (IPT) is described. The Doppler‐resolved spectra show that the perpendicular ion…
