First Detection of CO2 Emission in a Centaur: JWST NIRSpec Observations of 39P/Oterma
Abstract
JWST NIRSpec observed 39P on July 27, 2022, pre-perihelion, while at 5.82 au from the Sun. CO2 gas emission was detected; CO and H2O were not detected but 1-sigma upper limits were determined. These results are compared against other comets and Centaurs.
