Early eclipses of the Galilean satellites

Celestial Mechanics, 1982
A brief summary of the development of the theory of motion of the Galilean satellites is presented. Over 7700 eclipse observations have been collected and reduced using the Ephemeris E-2. They are of great potential in improving the ephemerides of the satellites and can yield important information on the evolution of the Galilean system.

The Galilean Satellites

Science, 1999
NASA's Galileo mission to Jupiter and improved Earth-based observing capabilities have allowed major advances in our understanding of Jupiter's moons Io, Europa, Ganymede, and Callisto over the past few years. Particularly exciting findings include the evidence for internal liquid water oceans in Callisto and Europa, detection of a strong intrinsic ...

Magnetospheres of the Galilean Satellites

Science, 1979
The plasma and field perturbations of magnetospheres that would surround magnetized galilean satellites embedded in the corotating jovian plasma differ from those produced by interaction with an unmagnetized conductor. If the intrinsic satellite dipole is antiparallel to that of Jupiter, the magnetosphere will be open. It is predicted that

Cassini VIMS observations of the Galilean satellites including the VIMS calibration procedure

Icarus, 2004
The Visual and Infrared Mapping Spectrometer (VIMS) observed the Galilean satellites during the Cassini spacecraft's 2000/2001 flyby of Jupiter, providing compositional and thermal information about their surfaces.

Galilean satellite obliquities

Journal of Geophysical Research: Planets, 2000
The obliquities, or angular separations between spin pole and orbit pole, for the Galilean satellites of Jupiter are all small but nonzero. We present calculations of the expected obliquity values based on the well known orbital parameters and recent estimates of the moments of inertia of the satellites, under the assumption that all are in Cassini ...

Galilean Satellites: Identification of Water Frost

Science, 1972
Water frost absorptions have been detected in the infrared reflectivities of Jupiter's Galilean satellites JII (Europa) and JIII (Ganymede). We have determined the percentage of frost-covered surface area to be 50 to 100 percent for JII, 20 to 65 percent for JIII, and possibly 5 to 25 percent for JIV (Callisto).

Masses of the Galilean Satellites of Jupiter

Science, 1976
Numerical data derived from the observation of the four great satellites of Jupiter are compared with the values obtained through Sampson's theory by using the new JPL (Jet Propulsion Laboratory) system of masses. It is not possible to fit the coefficient of the free oscillation in the longitude of Ganymede, whose argument is l

Rotation of Synchronous Satellites Application to the Galilean Satellites

Celestial Mechanics and Dynamical Astronomy, 2004
The equations of the \(n\)-body problem (and particularly, \( n=3 \) case) written in Keplerian variables have singularities in cases of orbits with small eccentricities and inclinations. On the contrary the Poincaré and the Laplace variables are regular for orbits with small eccentricities and inclinations, and are thus well suited for studying the ...
