Librational response of a deformed 3-layer Titan perturbed by non-keplerian orbit and atmospheric couplings

, 2014
The analyses of Titan's gravity field obtained by Cassini space mission suggest the presence of an internal ocean beneath its icy surface. The characterization of the geophysical parameters of the icy shell and the ocean is important to constrain the ...

Differentiating Plumes and Local Torus Segments of Enceladus

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Enceladus's south polar plumes and their surrounding torus segments (local plasma regions formed by plume material diffusion) are key to understanding its magnetospheric interaction; however, clear observational criteria to distinguish them remain lacking.

Saturnian Irregular Satellites as a Probe of Kuiper Belt Surface Evolution

The Planetary Science Journal
We present the JWST NIRSpec PRISM 0.7–5.3 μ m spectra of Albiorix and Siarnaq and the NIRSpec G235H/G395M 1.7–5.3 μ m spectra of Phoebe, the three largest Saturnian irregular satellites.

Ozone Production by Electron Irradiation of Regolith Ice: Laboratory Study for the Icy Moons

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract We irradiate fine‐grained regolith pure water ice in ultra high vacuum with 5keV $5\,\text{keV}$ and 10keV $10\,\text{keV}$ electrons to study the radiolysis of water ice. The ice regolith is designed to closely mimic the physical characteristics of the surfaces of the icy moons of the Solar System.

Structure of Jupiter's High‐Latitude Storms: Folded Filamentary Regions Revealed by Juno

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Sprawling, turbulent cloud formations dominate the meteorology of Jupiter's mid‐to‐high latitudes, known as Folded Filamentary Regions (FFRs). A multi‐wavelength characterization by Juno reveals the spatial distribution, vertical structure, and energetics of the FFRs.

Constraining Time Variations in Enceladus’s Water-vapor Plume with Near-infrared Spectra from Cassini’s Visual and Infrared Mapping Spectrometer

The Planetary Science Journal
Water vapor produces a series of diagnostic emission lines in the near-infrared between 2.60 and 2.75 μ m. The Visual and Infrared Mapping Spectrometer (VIMS) on board the Cassini spacecraft detected this emission signal from Enceladus’s plume, and so ...

Ice-Ocean Exchange Processes in the Jovian and Saturnian Satellites

Space Science Reviews, 2020
A growing number of satellites in the outer solar system likely have global oceans beneath their outer icy shells. While the presence of liquid water makes these ocean worlds compelling astrobiological targets, the exchange of heat and materials between the deep interior and the surface also plays a critical role in promoting habitable environments. In

Oscillatory Loading in Ice Friction Experiments: Implications for Tidally Driven Activity Along the Tiger Stripes of Enceladus

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.

Three-body resonance in meteoroid streams [PDF]

, 2016
Mean-motion resonances play an important role in the evolution of various meteoroid streams. Previous works have studied the effects of two-body resonances in different comets and streams. These already established two-body resonances were mainly induced

TRAPPED‐S, a New Environment Model Framework for Saturn: Focus on Radiation‐Specification Model

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract As space agencies contemplate missions to the outer planets' systems and moons, entailing prolonged observations via local orbiters or potential landers, meticulous assessment of the local environment—encompassing radiation and plasma conditions—is paramount for the design of both the platform and scientific payload.
