Evidence of an Extended Alfvén Wing System at Enceladus: Cassini's Multi‐Instrument Observations

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract We report in situ evidence for Enceladus' Alfvén wing system and its coupling with Saturn's ionosphere, based on multi‐instrument observations from the Cassini spacecraft. Analysis of 36 events, including 13 from non‐flyby paths, confirms the existence of a Main Alfvén Wing (MAW) current system generated at Enceladus, and associated Reflected ...

Differentiating Plumes and Local Torus Segments of Enceladus

open access: yesJournal 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.

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

open access: yesJournal 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.

Synthesis and thermal properties of dense Si─Al─C─N‐based polymer‐derived ceramics

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract In the present study, aluminum‐modified preceramic silicon polymers were synthesized via chemical modification of a commercially available organopolysilazane using an aluminum amido complex. The incorporation of aluminum into the polymer structure and its effect on ceramization behavior and processability as well as the thermal and mechanical ...
