JWST Reveals the Kuiper Belt-like Compositions of the Uranian Rings and Small Moons
Matthew Belyakov, M. Ryleigh Davis, Zachariah Milby +2
We present the JWST NIRSpec 1--5 micron spectra of the Uranian rings and four ringmoons: Puck, Perdita, Portia, and Juliet. We find that the compositions of the rings and moons str…
Callisto from JWST: CO2-rich terrain on the leading hemisphere and global patterns of H2O ice
Maria Camarca, Katherine de Kleer, Richard J. Cartwright +5
We present maps of H2O, CO2, and a 4.57 um spectral feature across Callisto's surface observed using the James Webb Space Telescope (JWST). H2O ice was mapped by measuring band par…
Neptune's Inner Moons and Rings Are Exposed Icy Body Interiors
M. Ryleigh Davis, Matthew Belyakov, Ian Wong +2
Neptune's single large moon, Triton, is accompanied by a set of dusty rings and small moons whose composition and origin are uncertain. Using the James Webb Space Telescope, we obs…
Detection of New Auroral Emissions at Io and Implications for Its Interaction with the Plasma Torus
Zachariah Milby, Katherine de Kleer, Carl Schmidt
We observed Io's optical aurora in eclipse on six nights between 2022 and 2024 using Keck I/HIRES. Spectra revealed 13 new auroral emissions not identified previously, tripling the…
FUOr-Aur 0544+3330: A New YSO Outburst in the Outskirts of Auriga OB1, Viewed Face-On
Lynne A. Hillenbrand, Adolfo S. Carvalho, Dan Stern +5
We present a newly appreciated FU Ori outburst event that began in 2019 and reached a peak in early 2021. Suspected young stellar object WISE J054452.25+333009.6 experienced substa…
A patchy CO exosphere on Ganymede revealed by the James Webb Space Telescope
Dominique Bockelée-Morvan, Olivier Poch, Françcois Leblanc +25
Jupiter's icy moon Ganymede has a tenuous exosphere produced by sputtering and possibly sublimation of water ice. To date, only atomic hydrogen and oxygen have been directly detect…
Short-Timescale Spatial Variability of Ganymede's Optical Aurora
Zachariah Milby, Katherine de Kleer, Carl Schmidt +1
Ganymede's aurora are the product of complex interactions between its intrinsic magnetosphere and the surrounding Jovian plasma environment and can be used to derive both atmospher…
JWST Spectrophotometry of the Small Satellites of Uranus and Neptune
Matthew Belyakov, M. Ryleigh Davis, Zachariah Milby +2
We use 1.4-4.6 micron multi-band photometry of the small inner Uranian and Neptunian satellites obtained with the James Webb Space Telescope's near-infrared imager NIRCam to charac…
Mass supply from Io to Jupiter's magnetosphere
L. Roth, A. Blöcker, K. de Kleer +24
Since the Voyager mission flybys in 1979, we have known the moon Io to be both volcanically active and the main source of plasma in the vast magnetosphere of Jupiter. Material lost…
The Optical Aurorae of Europa, Ganymede and Callisto
Katherine de Kleer, Zachariah Milby, Carl Schmidt +2
The tenuous atmospheres of the Galilean satellites are sourced from their surfaces and produced by a combination of plasma-surface interactions and thermal processes. Though thin,…
