The Jovian Irregular Satellites with MIRI LRS
The irregular satellites of Jupiter are a swarm of small, asteroid-like objects in orbit from ~100-400 Jupiter radii from the planet. These objects are thought to have been captured after the planet formed, although their precise origins remain obscure. Previous results have found the Jovian irregular satellites to contain a wide abundance of materials,Benjamin Sharkey +5 more

Chaoticity of the Jovian Irregular Satellites
2009Until now, the study of the chaoticity of the Jovian irregular satellites has been restricted to several ones and investigated on a limited integration time. We have extended these studies to the whole number of satellites and in time integration.

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.

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.

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

Polarimetric Modeling and Observations for the Jovian satellites
Photometric phase curves of airless Solar System objects exhibit a distinctive opposition effect, characterized by nonlinear brightening as phase angles approach backscattering. At phase angles less than approximately 20 degrees, polarimetric phase curves predominantly display a negative degree of linear polarizationThese phenomena arise from ...Ari Leppälä +5 more

CCD photometry for Jovian eclipses of the Galilean satellites
Icarus, 1992Abstract Timings of nine Jovian eclipses of the Galilean satellites observed during 1990 and 1991 are compared to predictions from modern ephemerides and are shown to exhibit very little internal scatter. These data can be used to supplement astrometry from the mutual occultations and eclipses of the satellites that occurred during the same time ...

Gravitational Heating of Jovian Satellites by Tidal Friction
1982Until quite recently, astronomical problems associated with tidal friction have arisen mainly in connection with the dynamics of the Earth-Moon system. However, since 1979, when the existence of phenomena thought to be of volcanic origin were detected by the Voyager spacecraft on the Jovian satellite Io, tidal friction was regarded also (among other ...

Jovian satellite Callisto: Possibility and consequences of its explosion
Earth, Moon, and Planets, 1989The numerous poorly understood differences between Ganymede and Callisto (the difference in the densities, in the degree of cratering and topography of the surface, the existence proper of craters and a difference of their distribution from that typical of bodies in the inner Solar System, etc.) find readily an explanation within the hypothesis of an ...
