Top panel: context of TOI-1431b, marked with a star symbol, with respect to all other known ultra hot Jupiter planets (T_eq > 2000 K). The planet-to-star distance (semi major axis) is shown in the horizontal axis, and the equilibrium temperature of the exoplanets is shown in the vertical axis. We note that only those planets with R_p > 0.6 R_J are shown. Bottom panel: context of TOI-1431b, marked with a star symbol, with respect to all the UHJ with known surface gravity (we excluded all planets whose masses have only upper limits). The equilibrium temperature is shown in the vertical axis and surface gravity of the planets in the horizontal axis. The marked planets are planets which atmospheres were studied before. For both figures the V band magnitude of the host star is colour-coded and the markers sizeis indicative of planet’s radius. The data is extracted from TEPCat catalogue (Southworth 2011).
