Rigid-body Numerical Integration of Io’s Physical Libration Under Multibody Perturbations

The Astronomical Journal
This study investigates the spin–orbit coupling of natural satellites, focusing on Io’s libration as a means of probing its internal structure and tidal responses.

Report of the Terrestrial Bodies Science Working Group. Volume 7: The Galilean satellites [PDF]

The formational and evolutionary history of natural satellites, their mineralogical composition and other phenomena of scientific interest are discussed. Key scientific questions about IO, Ganymede, Callisto, and Europa are posed and the measurements and

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.

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 ...

Fourier spectroscopy and planetary research [PDF]

The application of Fourier Transform Spectroscopy (FTS) to planetary research is reviewed. The survey includes FTS observations of the sun, all the planets except Uranus and Pluto, the Galilean satellites and Saturn's rings.
