Powering the Galilean Satellites with Moon‐Moon Tides [PDF]

open access: yesGeophysical Research Letters, 2020
AbstractThere is compelling evidence for subsurface water oceans among the three outer Galilean satellites and evidence for an internal magma ocean in the innermost moon, Io. Tidal forces from Jupiter periodically deform these bodies, causing heating and deformation that, if measured, can probe their interior structures.

A Primordial Origin of the Laplace Relation Among the Galilean Satellites

open access: yesScience, 2002
Understanding the origin of the orbital resonances of the Galilean satellites of Jupiter will constrain the longevity of the extensive volcanism on Io, may explain a liquid ocean on Europa, and may guide studies of the dissipative properties of stars and

Dynamics and distribution of Jovian dust ejected from the Galilean satellites [PDF]

open access: yesJournal of Geophysical Research E: Planets, 2016
In this paper, the dynamical analysis of the Jovian dust originating from the four Galilean moons is presented. High‐accuracy orbital integrations of dust particles are used to determine their dynamical evolution.

A semi-analytical model for exploring Galilean satellites formation from a massive disk [PDF]

open access: yes, 2015
A better knowledge of Jovian satellites' origins will bring light on the environment that surrounded Jupiter during its formation and can help us to understand the characteristics of this unique satellite system.

New Polarimetric Data for the Galilean Satellites: Io and Ganymede Observations and Modeling

open access: yesThe Planetary Science Journal
New high-precision disk-integrated measurements of the polarization of Io and Ganymede in the UBVRI bands are presented. The observations were obtained using polarimeters mounted on the Crimean Astrophysical Observatory and the Peak Terskol Observatory ...

Explaining the Galilean Satellites' Density Gradient by Hydrodynamic Escape. [PDF]

open access: yesAstrophys J Lett, 2020
The Galilean satellites exhibit a monotonic decrease in density (and increase in ice mass fraction) with distance from Jupiter. Whether this is because of the background conditions when they formed, the process of accretion itself, or later loss due to ...

Electron impact ionization in the icy Galilean satellites’ atmospheres [PDF]

open access: yesEuropean Physical Journal D : Atomic, Molecular and Optical Physics, 2023
Electron impact ionization is critical in producing the ionospheres on many planetary bodies and, as discussed here, is critical for interpreting spacecraft and telescopic observations of the tenuous atmospheres of the icy Galilean satellites of Jupiter (

Dynamical history of the Galilean satellites for a fast migration of Callisto [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2022
The dynamics of the innermost Galilean satellites (Io, Europa and Ganymede) is characterised by a chain of mean motion resonances, called Laplace resonance, and by a strong tidal dissipation that causes wide variations of their semi-major axes over ...

The 2021 mutual phenomena involving the Galilean satellites of Jupiter and the inner satellite Thebe [PDF]

open access: yes, 2023
Astrometric studies and orbital modeling of planetary moons have contributed significantly to advancing our understanding of their orbital dynamics. These studies require precise positions measured over extended periods.

Ion Implantation and Chemical Cycles in the Icy Galilean Satellites

open access: yesEarth, moon, and planets, 2023
An essential requisite for the appearance and permanence of life on Earth is the onset of a continuous “cycling” of some key atoms and molecules. Cycling of elements probably also occurs on other objects and is driven by biological or a-biological ...
