Jovian satellite positions from Hubble Space Telescope images
Icarus, 2004An accurate technique has been developed for measuring planetocentric positions of Jupiter's satellites from Wide Field/Planetary Camera images. Our method of finding the centers of the satellites and planet is based upon established limb-fitting techniques, but we have adapted those techniques to astrometry.

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 ...

Angular momentum transfer to the inner Jovian satellites
Nature, 1975Transfer of angular momentum from Jupiter to the four inner satellites in the presence of the Jovian magnetic field is considered. Electron-flux measurements near Io's flux tube and theoretical estimates of the electric currents flowing through the same flux tube are used to estimate the angular-momentum transfer during the evolutionary history of the ...

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.

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 ...

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
