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…
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 Volatile Composition and Thermal Physics in Comet C/2022 E3 (ZTF) Measured Near Closest Approach to Earth with NASA-IRTF
Nathan X. Roth, Michael A. DiSanti, Boncho P. Bonev +9
The 2023 perihelion passage of comet C/2022 E3 (ZTF) afforded an opportunity to measure the abundances and spatial distributions of coma volatiles in an Oort cloud comet at high sp…
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…
A D/H Ratio Consistent with Earth's Water in Halley-type Comet 12P from ALMA HDO Mapping
M. A. Cordiner, E. L. Gibb, Z. Kisiel +18
Isotopic measurements of Solar System bodies provide a primary paradigm within which to understand the origins and histories of planetary materials. The D/H ratio in particular, he…
