Origin of the jovian ring and the galilean satellites
Nature, 1979THE discovery by Voyager I of a thin flat stream of rocks orbiting Jupiter at a radius of some 130,000 km, or ∼2RP (Rp = 6.677 × 109 cm = present polar radius), in its equatorial plane opens a new avenue of information in our understanding of the formation of the Solar System.

Mutual phenomena of Jovian satellites
Journal of Astrophysics and Astronomy, 1991Results 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.

1979J2: The Discovery of a Previously Unknown Jovian Satellite
Science, 1980During a detailed examination of imaging data taken by the Voyager 1 spacecraft within 4.5 hours of its closest approach to Jupiter, a shadow-like image was observed on the bright disk of the planet in two consecutive wide-angle frames. Analysis of the motion of the image on the Jovian disk proved that it was not an atmospheric feature ...

Erosion of Galilean Satellite Surfaces by Jovian Magnetosphere Particles
Science, 1981The 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, 1975The 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

An evolutionary framework for the Jovian and Saturnian satellites
Earth, Moon, and Planets, 1987The position of the satellite within the protonebula, the influence of the parent planet, particularly the relative effects of tidal (gravitational) as opposed to radiogenic (internal) heat generating processes, as well as the type of ice, exert a control on the evolutionary histories of the Jovian and Saturnian satellites.

The galilean satellites and the Jovian magnetic field
The Moon and the Planets, 1978Alfven and Arrhenius (1974, 1976) have proposed that satellites may be formed by the condensation of plasma in partial corrotation in the dipole magnetic field of the central body. They conclude that the final orbit distance of the condensed material will be two-thirds of the orbit distance of the plasma.

Near-Infrared Observations of the Outer Jovian Satellites
Icarus, 2000Abstract On September 21, 1998, the outer jovian satellites Himalia (J6), Elara (J7), Carme (J11), Pasiphae (J8), and Sinope (J9) were detected in the J , H , and K s bandpasses in the course of the Two-Micron All Sky Survey. Similarities in near-infrared colors are consistent with the hypothesis that the outer satellites in prograde orbits are ...

The icy Jovian satellites after the Galileo mission
Reports on Progress in Physics, 2010The icy satellites of Jupiter, Callisto, Ganymede, Europa and Amalthea have diverse and remarkable characteristics. Their initial compositions were determined by conditions in the circum-Jovian nebula, just as the planets' initial properties were governed by their formation within the circumsolar nebula.

Regions of possible motions for new Jovian satellites
Solar System Research, 2007We 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
