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

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

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

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 ...

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

The origin of Jovian and Saturnian satellites in accretion disks
Solar System Research, 2006The properties of gas-dust disks that surrounded Jupiter and Saturn during the final stage of their formation are analyzed. The sizes of the disks are determined by the total planetocentric angular momentum of the matter accreted by planets and correspond to the sizes of the orbits of their largest satellites.

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 ...

Photometry and Astrometry of the Jovian satellites Amalthea and Thebe
2016During the 2014-2015 campaign of mutual events, we realized ground-based observations of Amalthea (JV) and Thebe (JXIV). We recorded two eclipses of Amalthea and, for the first time, one of Thebe by the Galilean moons. We used the 1-m telescope at Pic du Midi Observatory with an IR filter and a mask placed over the planetary image to reduce the light ...
