Joint Dynamical-geophysical Evidence For A Limit Cycle In The Galilean Moons
[astro-ph.EP] Io, Europa, and Ganymede orbit in the Laplace mean-motion resonance, where their orbital and thermochemical evolution are strongly coupled [1-5]. Forced eccentricities sustain tidal dissipation, powering Io’s volcanism and […]

Self-consistent 1D Modelling Of Jupiter’s Upper Atmosphere As An Exoplanet Analogue
[astro-ph.EP] Jupiter’s upper atmosphere provides a real-world laboratory for validating first-principles models of giant gaseous exoplanets and for constraining the key physical processes that govern them.

The Recent Crossing Of The 7:3 Resonance Between Ganymede And Callisto
[astro-ph.EP] Io, Europa and Ganymede are locked in the well-known Laplace resonance, while Callisto is not, even though it is very close to the 7:3 mean motion resonance with Ganymede. […]

Detection Of Propadiene (CH2CCH2), Propene (C3H6) And Non-detection Of Propane (C3H8) In Jupiter’s Northern Polar Stratosphere
We report the first detection of stratospheric propadiene (CH2CCH2) and propene (C3H6) at Jupiter’s mid-to-high northern latitudes using IRTF-TEXES measurements recorded on March 5-6, 2025.
