Multicolor photometry of outer Jovian satellites
Icarus, 1984Multicolor photometry was obtained of satellites J6 Himalia, J7 Elara, and J10 Lysithea in the prograde cloud of outer Jovian satellites, and of J8 Pasiphae, J9 Sinope, and J11 Carme in the retrograde cloud. The data for J9 are fragmentary; otherwise, the satellites all look like C-class asteroids, except J11, which shows a remarkable brightness in the

The Orbits of the Outer Jovian Satellites
Astronomical Journal, 2000 We report on the numerically integrated orbits for the nine outer Uranian satellites. The orbits are calculated based on fits to the astrometric observations for the period from 1984 to 2006. The results include the state vectors, post-fit residuals, and mean orbital elements.

The Orbits of the Retrograde Jovian Satellites
Icarus, 1993Abstract 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.

On the Inclination Distribution of the Jovian Irregular Satellites
Icarus, 2002Irregular satellites—moons that occupy large orbits of significant eccentricity e and/or inclination I—circle each of the giant planets. The irregulars often extend close to the orbital stability limit, about 1/3–1/2 of the way to the edge of their planet's Hill sphere. The distant, elongated, and inclined orbits suggest capture, which presumably would

Icarus, 1976
A brief review of the history of Jovian satellite nomenclature is given to indicate the background for the names proposed for the numbered satellites. The new names are consistent with established tradition and should cause minimal confusion with other named objects in the solar system.

Filamentation of Volcanic Plumes on the Jovian Satellite IO
Astrophysics and Space Science, 1988Volcanic 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 ...

Thermal history of the Jovian satellite Io
Icarus, 1987Abstract The discovery of large volcanic eruptions on Io suggests that Io is one of the most geologically active planetary bodies. The energy source of this geologic activity is believed to be tidal heating induced by Jupiter. A number of thermal history calculations were done to investigate the effect of tidal heating on the thermal history of Io ...

Jovian and Saturnian satellites
Reviews of Geophysics, 1987The 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.

Jovian satellite-satellite eclipses and occultations
Icarus, 1973Toward 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

Another 'Ocean' for a Jovian Satellite?
Science, 1999PLANETARY 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 ...
