Image Details
Caption: Figure 10.
Left panel: the left portion shows a comparison between the P-T profile from F. Yan et al. (2020), who used HARPS-N emission spectroscopy, and the the P-T profile constrained by A. G. Sreejith et al. (2023), who used CUTE NUV transit observations. The right portion shows the emission contribution function for the fiducial spectral template using the CUTE P-T profile. A strong neutral iron emission line core is indicated. Right panel: similar to the S/N maps of Figure 6, but shown for the fiducial spectral template that uses the P-T profile from CUTE and with chemical profiles computed using FASTCHEM. This spectral template is detected at S/N = 9.9.
