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…
