The vertical profile of CO in the atmosphere of Neptune from JCMT and IRAM observations
Résumé
In this paper, we will present a new observation of CO in the atmosphere of Neptune, obtained with the James Clerck Maxwell Telescope (JCMT) in the CO(6-5) line at 691.473GHz. We will present a joint analysis of this line and the CO(2-1) and CO(3-2) lines (published previously in [5, 6]) with the photochemical model we have developed in [10]. We will derive new constraints on the CO vertical profile in the upper atmosphere of Neptune and thus on the origin of this species.
