The composition of Saturn's rings
Kelly E. Miller, Gianrico Filacchione, Jeffrey Cuzzi +12
The origin and evolution of Saturn's rings is critical to understanding the Saturnian system as a whole. Here, we discuss the physical and chemical composition of the rings, as a f…
A SUBLIME 3D Model for Cometary Coma Emission: the Hypervolatile-Rich Comet C/2016 R2 (PanSTARRS)
M. A. Cordiner, I. M. Coulson, E. Garcia-Berrios +12
The coma of comet C/2016 R2 (PanSTARRS) is one of the most chemically peculiar ever observed, in particular due to its extremely high CO/H2O and N2+/H2O ratios}, and unusual trace…
The 3D Direct Simulation Monte Carlo Study of Europa Gas Plume
Wei-Ling Tseng, Ian-Lin Lai, Wing-Huen Ip +2
Europa has been spotted to have water outgassing activities by the space and ground-based telescopes as well as reanalysis of the Galileo data (Roth et al. 2014; Sparks et al. 2016…
Nanograin densities outside Saturn's A-ring
Robert E Johnson, Wei-Lin Tseng, Meredith K Elrod +1
The observed disparity between the radial dependence of the ion and electron densities measured by the Cassini plasma and radio science instruments are used to show that the region…
Seasonal and radial trends in Saturn's thermal plasma between the main rings and enceladus
Meredith K. Elrod, Wei-Ling Tseng, Adam K. Woodson +1
A goal of Cassini's extended mission has been to examine the seasonal variations of Saturn's magnetosphere, moons, and rings. Recently we showed that the magnetospheric plasma betw…
The Atomic Hydrogen Cloud in the Saturnian System
W. -L. Tseng, R. E. Johnson, W. -H. Ip
The Voyager flyby observations revealed that a very broad doughnut shaped distribution of the hydrogen atoms existed in the Saturnian magnetosphere. Recent Cassini observations con…
Modeling the Seasonal Variability of the Plasma Environment in Saturn's Magnetosphere between Main Rings and Mimas
W. -L. Tseng, R. E. Johnson, M. K. Elrod
The detection of O2+ and O+ ions over Saturn's main rings by the Cassini INMS and CAPS instruments at Saturn orbit insertion (SOI) in 2004 confirmed the existence of the ring atmos…
Cometary water expansion velocity from OH line shapes
W. -L. Tseng, D. Bockelée-Morvan, J. Crovisier +2
We retrieve the H_2O expansion velocity in a number of comets, using the 18-cm line shapes of the OH radical observed with the Nançay radio telescope. The H_2O velocity is derived…
