Transmission radii for cloud-free, hot-Jupiter exoplanets at solar composition for a planetary effective temperature of 1800 K, calculated with petitCODE (Mollière et al. 2015, 2017). The planet mass and radius were chosen to be identical to the values of Jupiter, and an internal temperature of T_int = 200 K was used. The opacity of TiO and VO was neglected. The host star was chosen to be a solar twin. Solid lines denote results obtained with the new Na wing profiles (presented in this paper), whereas dashed lines denote the results obtained with the Na lines reported in Allard et al. (2003). The inset plot shows the self-consistent temperature profiles for these cases, as calculated with petitCODE. In the example shown here the weaker absorption in the new Na wing profiles leads to more greenhouse heating in the deep layers of the atmosphere, while the upper layers are slightly cooler than what was obtained with the old profiles.
