The Orbits of the Retrograde Jovian Satellites

Icarus, 1993
Abstract The orbits of Jupiter's four retrograde satellites are strongly perturbed by the Sun and therefore resist treatment by the perturbative methods of classical celestial mechanics. We have integrated the orbits of these satellites over an interval of 2 Myr. We confirm the finding of A.L. Whipple and P.J.

Jovian satellite-satellite eclipses and occultations

Icarus, 1973
Toward the end of 1973 and in the first part of 1974, when the planes of the orbits of the four large Galilean satellites cross the sun and the earth, satellite-satellite eclipses and occultations will occur. Calculations indicate that during this period 350 such events will occur, most of them potentially observable. From observation of a few of these

Jovian and Saturnian satellites

Reviews of Geophysics, 1987
The years 1983‐1987 follow mankind's epochal first spacecraft encounters with the giant planets Jupiter and Saturn. Possibly the most spectacular “discoveries” there were the diversity and level of geological activity on the satellites that circle each.

Mutual phenomena of Jovian satellites

Journal of Astrophysics and Astronomy, 1991
Results of the observations of mutual eclipses of Galilean satellites observed from the Vainu Bappu Observatory during 1985 are presented. Theoretical models assuming a uniform disc, Lambert’s law and Lommel-Seeliger’s law describing the scattering characteristics of the surface of the eclipsed satellite were used to fit the observations.

Filamentation of Volcanic Plumes on the Jovian Satellite IO

Astrophysics and Space Science, 1988
Volcanic plumes on the Jovian satellite Io may be a visible manifestation of a plasma-arc discharge phenomenon. The amount of power in the plasma arc (~ 1011 W) is not enough to account for all the energy dissipated by the volcanoes. However, once a volcano is initiated by tidal and geologic processes, the dynamics of the volcanic plumes can be ...

Another 'Ocean' for a Jovian Satellite?

Science, 1999
PLANETARY SCIENCEObservations from the ground and the Galileo spacecraft suggest the existence of an ocean on the fiery Jovian satellite Io. But there are no tantalizing prospects for life in Io's proposed ocean. At something like 2000 Kelvin, the ocean seething beneath Io's volcanoes and lava lakes would vaporize the hardiest creature, for this ocean ...

Erosion of Galilean Satellite Surfaces by Jovian Magnetosphere Particles

Science, 1981
The Galilean satellites of Jupiter—Io (J1), Europa (J2), Ganymede (J3), and Callisto (J4)—are embedded in the intense ion and electron fluxes of the Jovian magnetosphere. The effect of these particles on the icy surfaces of the outer three satellites depends on the fluxes and the efficiency of the sputtering of water ice by such particles.

Galilean Satellites and Jovian Energetic Particles

Science, 1975
The observed infrared temperatures of the four Galilean satellites, Io, Europa, Ganymede, and Callisto, are inconsistent with their equilibrium temperatures. Since these satellites appear to have little or no atmosphere, the discrepancies may be explained as due to the heating of their surfaces by energetic particles from Jupiter's radiation belts. The

Dielectric Measurements of Saline Ices: Implication for Jovian Satellites Radar Exploration

Proceedings, 2011
A spacecraft in orbit around Jupiter's moon Ganimede can use ice penetrating radar to probe for a possible liquid water ocean beneath Ganimede's surface ice. The success of such a mission is constrained to the electromagnetic properties of ice, possible subsurface temperature gradients, and possible impurities in the ice.

Regions of possible motions for new Jovian satellites

Solar System Research, 2007
We present the results of our simulation and study of the regions of possible motions for 46 newly discovered Jovian satellites. We show that the orbits of some satellites (such as S/2003 J02, S/2003 J03, S/2003 J04, S/2003 J10, S/2003 J12, and S/2003 J23) presently cannot yet be determined with an acceptable accuracy for planning observations, because
