Crater size distributions on the Jovian satellites Ganymede and Callisto: Reassessment of Galileo and Voyager images, and an outlook to ESA's JUICE Mission [PDF]

, 2014
The crater distributions of the icy Jovian satellites Ganymede and Callisto, measured in Voyager and Galileo SSI data are discussed in the context of crater distributions on other bodies in the solar system.

Jovian Trojan N-Body Simulations

The Jovian Trojans are two swarms of asteroids, one ahead and one behind the orbit of Jupiter. These data are simulations of these objects over the 4.5 gya of the the solar system.

Thermally-Induced Chemistry and the Jovian Icy Satellites: A Laboratory Study of the Formation of Sulfur Oxyanions [PDF]

, 2011
Laboratory experiments have demonstrated that magnetospheric radiation in the Jovian system drives reaction chemistry in ices at temperatures relevant to Europa and other icy satellites.

Constraints from deuterium on the formation of icy bodies in the Jovian system and beyond

, 2008
International audienceWe consider the role of deuterium as a potential marker of location and ambient conditions during the formation of small bodies in our Solar system.

Resonant Structure and Chaotic Diffusion of the Jovian Irregular Satellites.

, 2010
International audienceThe dynamical region of the Jovian irregular satellites presents an interesting web of resonances. Along with secular and mean motion resonances which shape the stability regions, we report a number of resonances involving the Great

Spectral Decomposition Reveals Surface Processes on Europa

The Astrophysical Journal
Competing processes shape Europa’s surface: geological activity replenishes material through resurfacing, while bombardment by charged particles alters surface chemical composition. Each process leaves distinct spectral signatures.

Ion cyclotron waves: a tool for characterizing neutral particle profiles in extended exospheres

Frontiers in Astronomy and Space Sciences
Planetary exospheres are usually observed using transit spectroscopic methods, such as the Lyman-α line, which is mainly limited by interstellar medium absorption and airglow contamination from the geocorona when using low-orbit space telescopes or ...

Galileo observes electromagnetically coupled dust in the Jovian magnetosphere

, 1998
Measurements of dust coupled to the Jovian magnetosphere have been obtained with the dust detector on board the Galileo spacecraft. We report on data obtained during the first four orbits about Jupiter that had flybys of the Galilean satellites: Ganymede

Monte Carlo Calculation of Electron Energy Degradation in a Pure O2 Atmosphere

The Astrophysical Journal
Electron degradation serves as a significant energy source in planetary upper atmospheres. In this study, a Monte Carlo model is constructed to investigate the degradation of electrons in a pure O _2 atmosphere under the local approximation. Both elastic
