A JWST Study of Stardust. I. Infrared Spectroscopy of Comet 81P/Wild 2 and Overall Composition
Nathan X. Roth, Stefanie N. Milam, Diane H. Wooden +11
We report observations of comet 81P/Wild 2, target of the Stardust sample return mission, on UT 2023 March 20 and 24 at a heliocentric distance () of 1.85 au using the NIRSpec…
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…
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…
High nitrogen and carbon isotopic ratios in the interstellar comet 3I/ATLAS
C. Opitom, J. Manfroid, D. Hutsemékers +13
Interstellar objects provide a unique opportunity to further our understanding of the planetary formation process by studying in detail material formed around another star. Their i…
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…
Satellites and small bodies with ALMA: Insights into Solar System formation & evolution
Katherine de Kleer, Michael E. Brown, Martin Cordiner +1
Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large M…
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…
Zonal winds in Titan's middle atmosphere from a stellar occultation observed with Keck adaptive optics
Theresa C. Marlin, Eliot F. Young, Katherine de Kleer +9
We present spatially resolved Keck/NIRC2 images of a stellar occultation by Titan on September 5, 2022 and compare them to predictions from concurrent ALMA observations and a suite…
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…
Evidence for Surprising Heavy Nitrogen Isotopic Enrichment in Comet 46P/Wirtanen's Hydrogen Cyanide
M. A. Cordiner, K. Darnell, D. Bockeleé-Morvan +9
46P/Wirtanen is a Jupiter-family comet, probably originating from the Solar System's Kuiper belt, that now resides on a 5.4 year elliptical orbit. During its 2018 apparition, comet…
Chemical composition of comets C/2021 A1 (Leonard) and C/2022 E3 (ZTF) from radio spectroscopy and the abundance of HCOOH and HNCO in comets
N. Biver, D. Bockelee-Morvan, B. Handzlik +14
We present the results of a molecular survey of long period comets C/2021 A1 (Leonard) and C/2022 E3 (ZTF). Comet C/2021 A1 was observed with the IRAM 30-m radio telescope in Novem…
Thermal physics of the inner coma: ALMA studies of the methanol distribution and excitation in comet C/2012 K1 (PanSTARRS)
M. A. Cordiner, N. Biver, J. Crovisier +11
We present spatially and spectrally-resolved observations of CHOH emission from comet C/2012 K1 (PanSTARRS) using The Atacama Large Millimeter/submillimeter Array (ALMA) on 201…
