High water D/H ratio of the interstellar object 3I/ATLAS is consistent with a low-metallicity origin
Kenji Furuya, Martin Cordiner, Dominique Bockelée-Morvan +5
Recent JWST observations have revealed unusually high C/C ratios in carbon-bearing molecules of the interstellar object 3I/ATLAS, consistent with formation in a lower…
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…
Perihelion observations of interstellar comet 3I/ATLAS with the IRAM 30-m telescope
N. Biver, D. Bockelée-Morvan, R. Moreno +6
3I/ATLAS is the third interstellar comet identified as passing through the Solar System. Its high outgassing activity and favourable perihelion passage on October 29, 2025 UT provi…
Observations of Exocomets
Judith Korth, Azib Norazman, Raphäel Bendahan-West +6
Active small bodies in extrasolar systems, the extrasolar analogues of Solar System comets, provide insights into the orbital evolution and physical processes shaping planetary sys…
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…
