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…
CHOH and HCN in Interstellar Comet 3I/ATLAS Mapped with the ALMA Atacama Compact Array: Distinct Outgassing Behaviors and a Remarkably High CHOH/HCN Production Rate Ratio
Nathan X. Roth, Martin A. Cordiner, Dominique Bockelée-Morvan +15
We report the detection of methanol (CHOH) toward interstellar comet 3I/ATLAS using the Atacama Compact Array of the Atacama Large Millimeter/Submillimeter Array (ALMA) on UT 2…
The Evolution in Coma Molecular Composition of Comet C/2017 K2 (PanSTARRS) Across the HO Sublimation Zone: ALMA Imaging of an HO-Dominated Coma
Nathan X. Roth, Stefanie N. Milam, Martin A. Cordiner +8
We report a survey of molecular emission from cometary volatiles using the Atacama Large Millimeter/Submillimeter Array (ALMA) toward comet C/2017 K2 (PanSTARRS) carried out on UT…
Isotopic composition of cometary water and the origin of Earth's oceans
Dariusz C. Lis, Martin Cordiner, Nicolas Biver +4
Studies of the water content and isotopic composition of water-rich asteroids and comets are of key interest for understanding the late accretion stage of the Solar System cometary…
The Ongoing Decline in Activity of Comet 103P/Hartley 2
Ariel Graykowski, Guillaume Langin, David Chiron +102
We report photometric observations of Comet 103P/Hartley 2 during its 2023 apparition. Our campaign, conducted from August through December 2023, combined data from a global networ…
First Detection of Molecular Activity in the Largest Known Oort Cloud Comet: ALMA Imaging of C/2014 UN271 (Bernardinelli-Bernstein) at 16.6 au from the Sun
Nathan X. Roth, Stefanie N. Milam, Martin A. Cordiner +12
We report observations of comet C/2014 UN271 (Bernardinelli-Bernstein) carried out on UT 2024 March 8 and 17 at a heliocentric distance () of 16.6 au using the Atac…
Low NH/HO ratio in comet C/2020 F3 (NEOWISE) at 0.7 au from the Sun
Maria N. Drozdovskaya, Dominique Bockelée-Morvan, Jacques Crovisier +7
A lower-than-solar elemental nitrogen content has been demonstrated for several comets, including 1P/Halley and 67P/C-G with independent in situ measurements of volatile and refrac…
Gas and dust productions of comet 103P/Hartley 2 from millimetre observations: interpreting rotation-induced time variations
J. Boissier, D. Bockelée-Morvan, N. Biver +7
Comet 103P/Hartley 2 made a close approach to the Earth in October 2010. It was the target of an extensive observing campaign and was visited by the Deep Impact spacecraft (mission…
Millimetre continuum observations of comet C/2009 P1 (Garradd)
J. Boissier, D. Bockelée-Morvan, O. Groussin +7
Little is known about the physical properties of the nuclei of Oort cloud comets. Measuring the thermal emission of a nucleus is one of the few means for deriving its size and cons…

J. Boissier, D. Bockelée-Morvan, N. Biver +4
Comet 17P/Holmes underwent a dramatic outburst in October 2007, caused by the sudden fragmentation of its nucleus and the production of a large quantity of grains scattering sunlig…
