Transmission spectra (left), and dayside emission spectra (right) of our GCM simulations, for the short (blue solid line), and long (orange solid line) haze formation timescales. Dotted green lines show the spectrum before the radiative-feedback from haze was introduced. We include the available transmission spectra for HD 189733b from Cubillos et al. (2023), Sing et al. (2016), and Fu et al. (2024), as well as the MIRI LRS dayside emission data from Inglis et al. (2024) for illustration.
