JWST Spatial-Spectral Mapping of Green Comet C/2022 E3 (ZTF)
Stefanie N. Milam, Nathan X. Roth, Geronimo L. Villanueva +9
We report a survey of molecular emission from cometary volatiles using the James Webb Space Telescope (JWST) toward Oort cloud comet C/2022 E3 (ZTF) carried out on UT 2023 February…
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…
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…
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…
The interstellar heritage of comets
Karen Willacy, Liton Majumdar, Boncho Bonev +5
Comets have similar compositions to interstellar medium ices, suggesting at least some of their molecules maybe inherited from an earlier stage of evolution. To investigate the deg…
