Temperature plots for the WASP-76 b simulation (Schneider et al. 2022b) computed using the expeRT/MITgcm (Carone et al. 2020; Schneider et al. 2022c). Left: pressure–temperature profiles plotted at different longitudes on the planetary equator. Solid and dashed lines correspond to longitudes respectively eastwards and westwards of the substellar point. An isothermal upper atmosphere is assumed for pressures p < 10⁻⁵ bar. Right: temperature map as equatorial slice, plotted as a function of longitude and pressure. At the evening and morning limbs, radial lines indicate the opening angle that is probed during transit (32°), using the method of Wardenier et al. (2022).
