Neptune’s carbon monoxide profile and phosphine upper limits from Herschel/SPIRE: Implications for interior structure and formation

Abstract:

On Neptune, carbon monoxide and phosphine are disequilibrium species, and their abundance profiles can provide insights into interior processes and the external space environment. Here we use Herschel/SPIRE (Spectral and Photometric Imaging REceiver) observations from 14.9–51.5 cm-1 to obtain abundances from multiple CO and PH3 spectral features. For CO, we find that nine CO bands can be simultaneously fitted using a step profile with a 0.22 ppm tropospheric abundance, a 1.03 ppm stratospheri...
