The search for a subsurface ocean in Ganymede with Hubble Space Telescope observations of its auroral ovals

J Saur, S Duling, L Roth, X Jia… - Journal of …, 2015 - Wiley Online Library
We present a new approach to search for a subsurface ocean within Ganymede through
observations and modeling of the dynamics of its auroral ovals. The locations of the auroral …

A sublimated water atmosphere on Ganymede detected from Hubble Space Telescope observations

L Roth, N Ivchenko, GR Gladstone, J Saur… - Nature …, 2021 - nature.com
Ganymede's atmosphere is produced by charged particle sputtering and sublimation of its
icy surface. Previous far-ultraviolet observations of the O i 1,356 Å and O i 1,304 Å oxygen …

Surface composition and properties of Ganymede: Updates from ground-based observations with the near-infrared imaging spectrometer SINFONI/VLT/ESO

N Ligier, C Paranicas, J Carter, F Poulet, WM Calvin… - Icarus, 2019 - Elsevier
Ganymede's surface exhibits great geological diversity, with old dark terrains, expressed
