The position of HD 202772A b (red) in the space of mass, radius, and irradiation, compared to the population of known transiting gas giant planets (black). In the left panel, the solid lines mark theoretical models taken from Baraffe et al. (2014) for no core (black) and a 100 MEarth core (gray). The dashed lines are isodensity contours. Data were obtained from the NASA Exoplanet Archive (Akeson et al. 2013) on 2018 September 15.
