Mutual occultations and eclipses of the Galilean satellites of Jupiter in 1997: Astrometric results of observations

, 2009
International audienceIn 2006, a complete database of the international campaign on photometric observations of the Galilean satellites of Jupiter in the 1997 epoch of mutual occultations and eclipses was published.

Energy and Temperature Dependencies for Electron-induced Sputtering from H2O Ice: Implications for the Icy Galilean Moons

The Planetary Science Journal
To better assess the role that electrons play in exosphere production on icy bodies, we measured the total and O _2 sputtering yields from H _2 O ice for electrons with energies between 0.75 and 10 keV and temperatures between 15 and 124.5 K.

Tidal Seismicity in the Moon and Implications for the Rocky Interior of Europa

The Planetary Science Journal
Seismology is a powerful tool for probing the deep interiors of planetary bodies. Just as deep moonquakes triggered by Earth’s tides occur on the Moon, as observed by the Apollo seismometers, icy moons of the giant planets may also have seismically ...

The influence of internal global liquid layers on the obliquity of the Galilean Satellites

, 2011
The Galilean satellites (Io, Europa, Ganymede and Callisto) are synchronous satellites assumed to be locked in the Cassini state, an equilibrium state for the orientation of the rotation axis, first described for the Moon.

On the Divergent Evolution of Io and Europa as Primordial Ocean Worlds

The Astrophysical Journal
The Galilean moons exhibit a decrease in bulk density with distance from Jupiter, which may reflect differences in evolutionary paths and water loss. Early in its history, Jupiter was more luminous, which may have driven substantial atmospheric escape on

Spectroscopic Mapping of Callisto with HST/STIS and Implications for its Surface Composition

The Planetary Science Journal
We present global, spatially resolved ultraviolet–visible spectra of Callisto obtained with the Hubble Space Telescope/Space Telescope Imaging Spectrograph and explore possible compositions of Callisto’s surface material.

A Direct Simulation Monte Carlo–Driven Photochemical Model of Callisto’s Ionosphere

The Planetary Science Journal
Here we present a photochemical model of Callisto’s ionosphere with inputs supplied by a direct simulation Monte Carlo model of its neutral atmosphere. We compare a model that considers interactions with photons as the sole external ionization mechanism ...

The Near-infrared Spectral Characteristics of Water Ice, Epsomite, and Halite Mixtures Relevant to Europa

The Planetary Science Journal
We publish the first near-infrared spectra of grain particulate mixtures of water ice, epsomite, and halite at cryogenic temperatures. Furthermore, we perform a quantitative assessment of the ability of both intimately and linearly mixed models to ...
