Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.Abstract We explored the effect of oscillatory loading on the frictional response of polycrystalline water ice and ice + ammonia to better understand the behavior of tidally modulated strike‐slip faults on the icy satellites of the outer solar system, particularly Saturn's moon Enceladus.

Estimating the Initial Mass of the Gaia–Enceladus Dwarf Galaxy with a Chemical Evolution Model
The Astrophysical JournalThis work investigates the initial mass and chemical evolution history of the Gaia–Enceladus dwarf galaxy. We combine spectroscopic data from APOGEE with astrometric data from Gaia Data Release 3 to identify Gaia–Enceladus candidate stars via a machine ...

, 2017 Aegaeon, Methone, Anthe, and Pallene are four Saturnian small moons, discovered by the Cassini spacecraft. Although their orbital characterization has been carried on by a number of authors, their long-term evolution has not been studied in detail so far.

Geophysical Research Letters, 2009 Near infrared spectra of the surface of Enceladus returned by Cassini show the presence of an absorption feature at 3.53 μm, ascribed by Brown et al. (2006) to “short chain organics,” and by Newman et al. (2007) to hydrogen peroxide. We assign this feature tentatively to methanol.

The Effect of Salinity on Ocean Circulation and Ice–Ocean Interaction on Enceladus
The Planetary Science JournalObservational data suggest that the ice shell on Enceladus is thicker at the equator than at the pole, indicating an equator-to-pole ice flow. If the ice shell is in an equilibrium state, the mass transport of the ice flow must be balanced by the ...

Cassini CAPS‐ELS Observations of Low‐Energy Electron Beams Within Enceladus Mid‐Latitude Flux Tubes
Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract The electrodynamic interaction between Saturn's magnetosphere and Enceladus accelerates electrons along magnetic field lines. These electrons propagate inside magnetic flux tubes connecting the moon to the giant planet, generating distinctive auroral hiss and auroral footprint signatures, both previously observed by the Cassini spacecraft.

Enceladus’s Tidal Heating: A Simple Approach
The Planetary Science JournalSaturn’s moon Enceladus has a global ocean that is covered by an ice shell. The moon’s eccentric orbit forces the shell to librate, which distorts the shell and thereby generates heat.

Mapping spiral waves and other radial features in Saturn's rings
, 2017 We have analyzed the highest-quality images to be obtained by Cassini of Saturn's main rings after the Saturn Orbit Insertion (SOI) and before the Ring Grazing Orbits (RGO) and Grand Finale (GF).

Flux Tube Properties and Interchange Instabilities in Jupiter's Middle Magnetosphere
Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.Abstract In Jupiter's magnetosphere, the outward transport of Io‐genic plasma and the planetward injection of energetic particles are facilitated by flux tube interchange motion driven by centrifugal instabilities. Flux tube content and entropy are two competing key quantities that determine the behavior of the system.
