Tracing the source of carbon oxides on the large moons of Uranus
Richard J. Cartwright, Sasha Cryan, Rosario Brunetto +15
The Uranian moons Ariel, Umbriel, Titania, and Oberon are enriched in CO2 mixed with CO, but the origin(s) of these carbon oxides, be they primarily native or radiolytic, remains u…
LEAP: A Rapid Neural Surrogate of Multi-Fluid MHD at Europa
Sachin Alexander Reddy, Abigail R. Azari, Corey J. Cochrane +6
Characterizing Europa's subsurface ocean is a key objective of the Europa Clipper and JUICE missions in the search for life beyond Earth. Although the ocean's induced magnetic fiel…
Universal energy limits of radiation belts in planetary and brown dwarf magnetospheric systems
Drew L. Turner, Savvas Raptis, Adnane Osmane +5
Radiation belts are regions of magnetically trapped particle radiation found around all of the sufficiently magnetized planets in the Solar System and recently also observed around…
Laboratory Investigation of CO2-Driven Enhancement of Radiolytic H2O2 on Europa and Other Icy Moons
Bereket D. Mamo, Ujjwal Raut, Ben D. Teolis +5
Observations of Europa's leading hemisphere reveal elevated H2O2 in the warmer, low latitude chaos terrains compared to the colder, polar regions. This distribution disagrees with…
Fluorescent Biomolecules Detectable in Near-Surface Ice on Europa
Gideon Yoffe, Keren Duer, Tom Andre Nordheim +2
Europa, Jupiter's second Galilean moon, is believed to host a subsurface ocean in contact with a rocky mantle, where hydrothermal activity may drive the synthesis of organic molecu…
JWST Reveals Spectral Tracers of Recent Surface Modification on Europa
Richard J. Cartwright, Charles A. Hibbits, Bryan J. Holler +9
Europa has been modified by a variety of geologic processes, exposing internally-derived materials that are heavily irradiated by charged particles trapped in Jupiter's magnetosphe…
