Absorption of trapped particles by Jupiter's moons [PDF]

Absorption effects of the four innermost moons in the radial transport equations for electrons and protons in Jupiter's magnetosphere are presented. The phase space density n at 2 R sub J for electrons with equatorial pitch angles less than 69 deg is ...

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 ...

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

On the Origin and Dynamical Evolution of Jupiter’s Moon Amalthea

The Astrophysical Journal
Interior to the orbits of Jupiter’s iconic Galilean moons are four small satellites with individual mean radii R  ≲ 84 km. Multiple lines of evidence suggest that these bodies formed at a more distant location in Jupiter’s circumplanetary disk before ...

Global Distribution of the Key Species on the Surface of Europa

The Astrophysical Journal
The icy surface of Europa is continuously bombarded by ions and electrons from Jupiter’s magnetosphere. The bombardment of the particles dissociates water molecules on the surface of Europa and introduces impurities to the icy surface.
