Wanted: An International Jovian-Satellite-Phenomenon Centre [PDF]
International Astronomical Union Colloquium, 1988 AbstractAmateur observations made since 1977 show that although the ephemerides for the satellites of Jupiter published by the Jet Propulsion Laboratory are more accurate than those in the Astronomical Almanac, there are still small deviations, which may increase with time.

Discovery of Two Additional Jovian Irregulars
, 2012 International audienceWe report on the discovery of two previously undetected irregular satellites of Jupiter (S/2010 J 1 and S/2010 J 2) during recovery observations of other known satellites.

Spectral Decomposition Reveals Surface Processes on Europa
The Astrophysical JournalCompeting 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.

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

Cryovolcanism on the icy satellites
, 1994 Evidence of past cryovolcanism is widespread and extremely varied on the icy satellites. Some cryovolcanic landscapes, notably on Triton, are similar to many silicate volcanic terrains, including what appear to be volcanic rifts, calderas and solidified ...

The Astrophysical Journal LettersRed spectral slopes (i.e. increasing reflectance with increasing wavelength) and featureless 0.5–2.5 μ m spectra are often associated with the presence of organic material, and there is a sense that the redder the slope, the more organic material is ...
