IFU Observations of Comet 3I/ATLAS = C/2025 N1 (ATLAS) using the Hobby-Eberly Telescope with the VIRUS Instrument
Anita Cochran, Gregory Zeimann, Emmanuel Jehin +2
We observed interstellar object 3I/ATLAS = C/2025 N1 (ATLAS) on 9 December 2025 UT with the VIRUS spectrograph on the Hobby-Eberly Telescope. VIRUS is a low spectral resolving powe…
Observations of [O I] emission in Comets C/2014 Q2 (Lovejoy) and C/2007 N3 (Lulin): Possible Influence of Solar Activity on Oxygen Line Ratios
Ella J. Mayfield, Adam J. McKay, Michael S. P. Kelley +1
Observing [O I] emission to calculate an "oxygen line ratio" has been proposed as a potential proxy for direct CO measurement in comets. However, the photochemistry governing […
Watching a Comet Turn On: High Spectral Resolving Power Observations of Comet C/2017 K2 (PanSTARRS)
Anita L. Cochran, Adam J. McKay, Youssef Moulane
We report high spectral resolving power optical observations of comet C/2017\,K2 (PanSTARRS) as it approached the Sun. This comet was discovered when it was 16\,{\sc au} from the S…
Inferring the CO2 Abundance in Comet 45P/Honda-Mrkos-Pajdušáková from [O I] Observations: Implications for the Source of Icy Grains in Cometary Comae
Mikayla R. Huffman, Adam J. McKay, Anita L. Cochran
The study of cometary composition is important for understanding our solar system's early evolutionary processes. Carbon dioxide (CO2) is a common hypervolatile in comets that can…
What Does It Mean to be a "Depleted" Comet? High Spectral Resolution Observations of the Prototypical Depleted Comet 21P/Giacobini-Zinner from McDonald Observatory
Anita L. Cochran, Tyler Nelson, Adam J. McKay
We present high spectral resolution optical observations of comet 21P/Giacobini-Zinner from six nights in 2018. The observations were obtained with the Tull coude spectrograph on t…
The Crucial Role of Ground- and Space-Based Remote Sensing Studies of Cometary Volatiles in the Next Decade (2023-2032)
Nathan X. Roth, Dennis Bodewits, Boncho Bonev +15
The study of comets affords a unique window into the birth, infancy, and subsequent history of the solar system. There is strong evidence that comets incorporated pristine interste…
