Geology of the Selk crater region on Titan from Cassini VIMS observations [PDF]
, 2010 International audienceObservations of Titan obtained by the Cassini Visual and Infrared Mapping Spectrometer (VIMS) have revealed Selk crater, a geologically young, bright-rimmed, impact crater located similar to 800 km north-northwest of the Huygens ...

Structural geology of Ganymede regional groove systems (60°N–60°S)
Journal of Maps, 2020 Brittle deformation on Ganymede surface is represented by grooves tectonic linear landforms. These are regional scale structures that show well-defined morphology from straight to curvilinear. High density of grooves occupies most of the light terrain of

The NIR transmission spectrum of Jupiter from the observation of a Ganymede’s eclipse
EPJ Web of Conferences, 2015 Here, we report the NIR transmission spectrum of Jupiter, with high signal-to-noise ratio, as if it were a transiting planet. Our technique was to observe Ganymede, when crossing Jupiter’s shadow.

Early Stages of Galilean Moon Formation in a Water-depleted Environment
The Astrophysical Journal Letters, 2023 A key feature of the Galilean satellite system is its monotonic decrease in bulk density with growing distance from Jupiter, indicating an ice mass fraction that is zero in the innermost moon Io and about half in the outer moons Ganymede and Callisto ...

The generation of Ganymede's diffuse aurora through pitch angle scattering [PDF]
Annales Geophysicae, 2017 Diffuse auroral intensities of neutral atomic oxygen OI λ1356 Å emission on Ganymede due to whistler mode waves are estimated. Pitch angle diffusion of magnetospheric electrons into the loss cone due to resonant wave–particle interaction of whistler ...

Evidence for Magnetic Reconnection at Ganymede's Upstream Magnetopause During the PJ34 Juno Flyby
Geophysical Research Letters, 2022 Juno made a close flyby of Ganymede and flew through its magnetosphere on 7 June 2021, including an outbound crossing of Ganymede's upstream magnetopause. We present plasma and magnetic field observations near the upstream magnetopause from Juno's Jovian

Mapping and analysis of bulged impact craters on Ganymede
, 2022 reservedABSTRACT - L’obiettivo di questa tesi è quello di studiare la morfologia e la distribuzione dei crateri d’impatto sulla superficie di Ganimede, focalizzandoci principalmente su quelli definiti di tipo “bulged”.

core
Crystals, 2021 The core of Ganymede is suggested to be mainly Fe but with a significant proportion of S. Effects of S as a core constituent are freezing-point depression, allowing for a molten core at relatively low core temperatures, and modification of transport ...

Measuring Ganymede’s Librations with Laser Altimetry
Geosciences, 2019 Jupiter’s moon Ganymede might be in possession of a subsurface ocean located between two ice layers. However, from Galileo data it is not possible to unambiguously infer the thickness and densities of the individual layers.
