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…

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…

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…
