Water D/H in 3I/ATLAS as a Probe of Formation Conditions in Another Planetary System
Luis E. Salazar Manzano, Teresa Paneque-Carreño, Martin A. Cordiner +17
Water reservoirs in the Solar System exhibit a deuterium enrichment that links back to the physical environment at the time of stellar birth. Gas-phase and ice-grain deuterium enri…
Monitoring Volatile Evolution in Disrupting Comet D/2021 A1 (Leonard) with NOEMA and APEX
Timothy N. Proudkii, Nathan X. Roth, Jérémie Boissier +8
We report a pre-perihelion survey of volatile emissions from comet D/2021 A1 (Leonard) with the Northern Extended Millimeter Array (NOEMA; UT 2021 Nov. 5, 21, and Dec. 1) and the A…
Isotopic Evidence for a Cold and Distant Origin of the Interstellar Object 3I/ATLAS
Martin Cordiner, Nathan X. Roth, Marco Micheli +16
Interstellar objects provide the only directly observable samples of icy planetesimals formed around other stars, and can therefore provide insight into the diversity of physical a…
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…
An Enriched Methane D/H Ratio in the Interstellar Object 3I/ATLAS
Nathan X. Roth, Martin Cordiner, Stefanie Milam +15
Interstellar objects are interlopers from other planetary systems, and their volatile compositions provide a glimpse into planet formation around their host star. We present near-i…
A Multi-Wavelength Study of Comet C/2022 E3 (ZTF): Complementary ALMA and JWST Investigations of Water and Methanol in Cometary Comae
K. D. Foster, M. A. Cordiner, Nathan X. Roth +7
Long-period comets, which are often considered to be representative of material in the protoplanetary disk that formed the Solar System, are ideal to investigate the question of ch…
