Exploring Enceladus's Interior Structure Using Electromagnetic Induction

Alexander Grayver, Joachim Saur

Electromagnetic (EM) sounding can constrain the electrical structure of Enceladus and, in turn, the salinity of its ocean and the porosity, fluid content, and thermal state of its…

Constraining Electron-Impact Ionization of O Through UV Aurora Observations at Ganymede

Stefan Duling, Joachim Saur, Darrell Strobel +3

While photoionization rates of Ganymede's O dominated atmosphere are well constrained, the contribution of electron-impact ionization is rather uncertain. Previous quantitative…

Investigating Magnetic Field Fluctuations in Jovian Auroral Electron Beams

A. Salveter, J. Saur, G. Clark +4

The Juno spacecraft provides a unique opportunity to explore the mechanisms generating Jupiter's aurorae. Past analyses of Juno data immensely advanced our understanding of its aur…

Observed Latitudinal, Longitudinal and Temporal Variability of Io's Atmosphere Simulated by a Purely Sublimation Driven Atmosphere

A. -C. Dott, J. Saur, S. Schlegel +3

How much of Io's SO atmosphere is driven by volcanic outgasing or sublimation of SO surface frost is a question with a considerable history. We develop a time dependent sur…

Mass supply from Io to Jupiter's magnetosphere

L. Roth, A. Blöcker, K. de Kleer +24

Since the Voyager mission flybys in 1979, we have known the moon Io to be both volcanically active and the main source of plasma in the vast magnetosphere of Jupiter. Material lost…

Corotation-bounce resonance of ions in Jupiter's magnetosphere

Y. Sarkango, J. R. Szalay, P. A. Damiano +6

Banded energy distributions of H, O, S, and O or S ions between 100 eV to ~20 keV are consistently observed in Jupiter's magnetosphere mapping to M-…
