Predictions of observation for a 1-bar atmosphere produced from a low fo₂ and high fo₂ rocky interior for GJ 1132b. (Top left panel) Emission spectra of the high fo₂ and low fo₂ 1-bar atmosphere. Blackbody emission spectra at different temperatures are plotted for comparison (dashed curves). (Top right panel) Contribution function calculated with HELIOS to assess the pressure and temperature probed in emission with different spectral bins for the high fo₂ case. (Bottom panels) Transit spectra focusing on the NIRSpec range of JWST, with the contribution of the different species on the observed signatures for the low fo₂ scenario (left) and high fo₂ scenario (right).
