Photospheric emission of WASP-80 obtained from MARCS models (black line) and the MUSCLES SED of GJ832 (red line) rescaled in such a way as to reproduce the XUV emission of WASP-80 derived from the X-ray measurements and the scaling relations of King et al. (2018). The MARCS model has been convolved to a resolution comparable to that of the MUSCLES spectrum of GJ832 in the optical and infrared. The blue line shows the average XUV stellar emission at the distance of the planet. For reference, the vertical dashed lines indicate, from left to right, the position of the hydrogen ionisation threshold (≈912 Å), the position of the metastable He I ionisation threshold (≈2600 Å), and the approximate position of the He I features (≈10 830 Å).
