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…
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…
Alternating north-south brightness ratio of Ganymede's auroral ovals: Hubble Space Telescope observations around the Juno PJ34 flyby
Joachim Saur, Stefan Duling, Alexandre Wennmacher +17
We report results of Hubble Space Telescope observations from Ganymede's orbitally trailing side which were taken around the flyby of the Juno spacecraft on June 7, 2021. We find t…
Mapping the Brightness of Ganymede's Ultraviolet Aurora using Hubble Space Telescope Observations
Alexander Marzok, Stehpan Schlegel, Joachim Saur +4
We analyze Hubble Space Telescope (HST) observations of Ganymede made with the Space Telescope Imaging Spectrograph (STIS) between 1998 and 2017 to generate a brightness map of Gan…
Science goals and new mission concepts for future exploration of Titan's atmosphere geology and habitability: Titan POlar Scout/orbitEr and In situ lake lander and DrONe explorer (POSEIDON)
Sébastien Rodriguez, Sandrine Vinatier, Daniel Cordier +61
In response to ESA Voyage 2050 announcement of opportunity, we propose an ambitious L-class mission to explore one of the most exciting bodies in the Solar System, Saturn largest m…
