General Circulation Model Constraints on the Detectability of the CO2-CH4 Biosignature Pair on TRAPPIST-1e with JWST

Terrestrial exoplanets such as TRAPPIST-1e will be observed in a new capacity with the JWST/Near Infrared Spectrograph (NIRSpec), which is expected to be able to detect CO _2 , CH _4 , and O _2 signals, if present, with multiple coadded transit observations. The CO _2 -CH _4 pair in particular is th...
