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…
Multiband Color Monitoring of 3I/ATLAS through Ground-Based Relay Observations
Ariel Graykowski, Bryce Bolin, Laura-May Abron +140
We present multiband, long-baseline photometric observations of interstellar comet 3I throughout its 2025--2026 apparition using coordinated ground-based global relay observations.…
Gemini and Apache Point Multi-band Optical Imaging Characterization of Fragmenting Long-period Comet C/2025 K1 (ATLAS)
Carl Ingebretsen, Bryce T. Bolin, Meredith A. MacGregor +8
We present results from multi-band g, r, and i, observations of C/2025 K1 (ATLAS) taken with the Gemini North 8.1-m/GMOS imager on 2025 December 6 and December 24, and u, g, r, i,…
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…
Nereid as a Regular Satellite of Neptune
Matthew Belyakov, M. Ryleigh Davis, Ian Wong +2
Nereid, Neptune's third largest moon, is considered to be a captured irregular satellite due to its highly eccentric orbit. However, among irregular satellites, Nereid is an outlie…
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…
