Theory of the rotation of the Galilean satellites [PDF]

Proceedings of the International Astronomical Union, 2010
AbstractAs most of the natural satellites of the Solar System, the Galilean moons are since a long time assumed to be tidally locked in a spin-orbit synchronous resonance. Thanks to the mission Galileo, we now dispose of enough gravity data to perform 3-dimensional theories of the rotation of these satellites, in particular to model the departure from ...

A virtual tour of the Galilean Satellites [PDF]

Proceedings of the International Astronomical Union, 2010
Galileo's imagination was quick to comprehend the importance of the 4 starry objects he observed near Jupiter in January 1610, not only for himself as a scientist but for our common understanding of the place of the Earth and our species in the cosmos.

The Galilean Satellites Formed Slowly from Pebbles [PDF]

, 2019
It is generally accepted that the four major (Galilean) satellites formed out of the gas disk that accompanied Jupiter's formation. However, understanding the specifics of the formation process is challenging, as both small particles (pebbles) and the ...

Photophoresis in the circumjovian disk and its impact on the orbital configuration of the Galilean satellites

, 2019
Jupiter has four large regular satellites called the Galilean satellites: Io, Europa, Ganymede, and Callisto. The inner three of the Galilean satellites orbit in a 4:2:1 mean motion resonance; therefore their orbital configuration may originate from the ...

Probing Ganymede’s Atmosphere with HST Lyα Images in Transit of Jupiter

The Planetary Science Journal, 2023
We report results from far-ultraviolet observations by the Hubble Space Telescope of Jupiter’s largest moon, Ganymede, transiting across the planet’s dayside hemisphere.

Galilean Satellites and the Galileo Space Mission [PDF]

International Astronomical Union Colloquium, 1997
AbstractThe Galileo spacecraft arrived at Jupiter in December 1995 to start its two-year mission of exploring the Jovian system. The spacecraft will complete eleven orbits around Jupiter and have ten more close encounters with the outer three Galilean satellites, after the initial close approach to Io on December 7, 1995.

Ice chemistry on the Galilean satellites [PDF]

Journal of Geophysical Research: Planets, 1998
Jupiter's icy satellites Europa, Ganymede, and Callisto are subject to energy fluxes from electrons, photons, and magnetospheric plasma ion bombardment. As water ice and CO2 ice are thought to be present on their surfaces, the radiolysis of these materials over time should produce more complicated CHO‐containing molecules. These may include CH3OH, H2CO,

Detecting Exomoons from Radial Velocity Measurements of Self-luminous Planets: Application to Observations of HR 7672 B and Future Prospects

The Astronomical Journal, 2023
The detection of satellites around extrasolar planets, so called exomoons, remains a largely unexplored territory. In this work, we study the potential of detecting these elusive objects from radial velocity monitoring of self-luminous, directly imaged ...

Theory of Motion of Jupiter’s Galilean Satellites [PDF]

International Astronomical Union Colloquium, 1978
AbstractThe final results for the theory enabling one to calculate the positions of the Galilean satellites and their partial derivatives are presented, following the techniques outlined in earlier papers. Extensive use of algebraic manipulation software on a digital computer is employed to generate the final expressions.

Mass-wasting Features on Galilean Icy Moons: Morphological Analysis and Implications

The Planetary Science Journal
This study investigates mass-wasting features on the icy Galilean satellites Europa, Ganymede, and Callisto. Through comparative morphological analysis, we identified and classified slides, slumps, and flow-like deposits as mass-wasting categories using ...
