Haze (tholin and soot) models from B. Jacobs et al. (2023) for two metallicities: [M/H] = 0 (solid) and [M/H] = 1 (dashed). The various formation rates are shown in cool colors for the tholins and in warm colors for the soots. The haze models are compared to the NIRISS/SOSS eclipse spectrum of WASP-80 b. If the aerosols are hazes, they could consist of soots or tholins, with formation rates for tholins most likely lower than 10−11.5 g cm−2 s−1.
