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…
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…
Deuterated water and the formation of the satellites of Uranus
Michael E. Brown, Matthew Belyakov, Swaroop Chandra +5
The satellites of Uranus orbit in a low-eccentricity, equatorial plane that is tilted by 98 degrees relative to the solar system -- a geometry that mirrors Uranus's extreme axial t…
JWST/MIRI Finds ISM-like Amorphous Silicates in Interstellar Comet 3I/ATLAS
Matthew Belyakov, Ian Wong, Carey M. Lisse +7
We present the first spectroscopic mineralogical analysis of the dust coma of an interstellar object (ISO) from JWST mid-infrared spectroscopy of 3I/ATLAS (3I). 3I exhibits a stron…
The Volatile Inventory of 3I/ATLAS as seen with JWST/MIRI
Matthew Belyakov, Ian Wong, Bryce T. Bolin +4
We present the first spectroscopic characterization of an interstellar object at mid-infrared wavelengths. Post-perihelion observations of 3I/ATLAS using the JWST/MIRI medium-resol…
Deuterated water ice on the satellites of Saturn
Michael E. Brown, Samantha K. Trumbo, M. Ryleigh Davis +1
The deuterium to hydrogen ratio in water ice in a planetary body carries important information on the history of water processing and delivery in the protostellar nebula. For a gia…
Palomar and Apache Point Spectrophotometry of Interstellar Comet 3I/ATLAS
Matthew Belyakov, Christoffer Fremling, Matthew J. Graham +7
On July 1st 2025 the third interstellar object, 3I/ATLAS or C/2025 N1 (ATLAS), was discovered, with an eccentricity of and perihelion of au. We…
A JWST study of CO on the satellites of Saturn
Michael E. Brown, Samantha K. Trumbo, Matthew Belyakov +2
Solid state CO has been detected throughout the outer solar system, even at temperatures where crystalline CO is unstable, requiring that the CO be trapped in a separat…
Spectroscopic Mapping of Callisto with HST/STIS and Implications for its Surface Composition
M. Ryleigh Davis, Samantha K. Trumbo, Michael E. Brown +1
We present global, spatially resolved ultraviolet-visible spectra of Callisto obtained with HST/STIS and explore possible compositions of Callisto's surface material. We map the st…
Pwyll and Manannán Craters as a Laboratory for Constraining Irradiation Timescales on Europa
M. Ryleigh Davis, Michael E. Brown
We examine high spatial resolution Galileo/NIMS observations of the young (~1 My - 20 My) impact features, Pwyll and Manannán craters, on Europa's trailing hemisphere in an effort…
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…
The Spatial Distribution of the Unidentified 2.07 \textmu m Absorption Feature on Europa and Implications for its Origin
M. Ryleigh Davis, Michael E. Brown, Samantha K. Trumbo
A weak absorption feature at 2.07 \textmu m on Europa's trailing hemisphere has been suggested to arise from radiolytic processing of an endogenic salt, possibly sourced from the i…
Spectroscopic mapping of Io's surface with HST/STIS: SO frost, sulfur allotropes, and large-scale compositional patterns
Samantha K. Trumbo, M. Ryleigh Davis, Benjamin Cassese +1
Io's intense volcanic activity results in one of the most colorful surfaces in the solar system. Ultraviolet and visible-wavelength observations of Io are critical to uncovering th…
