JWST Reveals Refractory-Rich Water Ice in Interstellar Comet 3I/ATLAS: Evidence for a Continuum of Grain Properties across Protoplanetary Disks
Silvia Protopapa, Michael S. P. Kelley, Martin A. Cordiner +12
We present JWST/NIRSpec PRISM observations of the interstellar comet 3I/ATLAS obtained on 2025 August 6 (Epoch 1), 2025 December 22 (Epoch 2), and 2026 April 1 (Epoch 3), spanning…
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…
Mars, a Post-Habitable Planet?
Matteo Crismani, Richard Cartwright, Michael Chaffin +3
Mars provides a critical analog to once habitable exoplanets that have since lost their surface liquid water. The current atmospheric state of Mars retains the chemical fingerprint…
JWST and Gemini Observations of the Active Centaur 450P/LONEOS: Nucleus and Coma Characterizations
Charles A. Schambeau, Michael S. P. Kelley, Maria Womack +16
Between 2019 and 2024, we used the Gemini-N and JWST observatories to conduct a detailed case study of the active Centaur 450P/LONEOS, whose orbit was significantly altered by a cl…
Coma Physics of an Interstellar Object: JWST Spatial-Spectral Mapping of 3I/ATLAS
Nathan X. Roth, Martin A. Cordiner, Stefanie N. Milam +17
We report a survey of molecular emission from cometary volatiles using the James Webb Space Telescope (JWST) toward interstellar object 3I/ATLAS carried out on UT 2025 December 22…
