Long-term evolution of the Galilean satellites: the capture of Callisto into resonance [PDF]
Astronomy & Astrophysics, 2020 Context. The Galilean satellites have very complex orbital dynamics due to the mean-motion resonances and the tidal forces acting in the system. The strong dissipation in the couple Jupiter–Io is spread to all the moons involved in the so-called Laplace ...

Monthly notices of the Royal Astronomical Society, 2022 2021 was the year of Jupiter’s equinox, that is the Sun and the Earth passed through the equatorial plane of the planet and therefore the orbital planes of its main satellites.

Reflected Light Observations of the Galilean Satellites from Cassini: A Test Bed for Cold Terrestrial Exoplanets [PDF]
Astronomical Journal, 2020 For terrestrial exoplanets with thin or no atmospheres, the surface contributes light to the reflected light signal of the planet. Measurement of the variety of disk-integrated brightnesses of bodies in the solar system and the variation with ...

New Polarimetric Data for the Galilean Satellites: Europa Observations and Modeling
The Planetary Science Journal, 2022 This paper is dedicated to a long-standing problem of the shape of the negative branch of polarization (NBP) for Jupiter's moon Europa, determination of which is crucial for the characterization of the icy regolith on this satellite and similar objects ...

The Planetary Science Journal, 2021 We observed Jupiter’s thermal emission with SOFIA/FORCAST in 2018 August and 2019 July. Both broad-band images (8–37 μm) and spectra (17–37 μm) were obtained.

The Galilean Satellites Formed Slowly from Pebbles [PDF]
Astrophysical Journal, 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 [PDF]
Astronomy & Astrophysics, 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 ...

A semi-analytical model of the Galilean satellites’ dynamics [PDF]
Celestial mechanics & dynamical astronomy, 2018 The Galilean satellites’ dynamics has been studied extensively during the last century. In the past it was common to use analytical expansions in order to get simple models to integrate, but with the new generation of computers it became prevalent the ...

Arecibo Radar Astrometry of the Galilean Satellites from 1999 to 2016
Astronomical Journal, 2020 Harmon et al. Arecibo radar observations from 1992 provided some of the most precise line-of-sight distance (ranging) measurements of Ganymede and Callisto to date.

Thermal infrared spectroscopy of Europa and Callisto [PDF]
, 2000 The trailing hemispheres of Europa and Callisto were observed at 9–13 μm, and a spectrum of Europa with better spectral resolution and a better signal-to-noise ratio than was previously possible has been derived.
