Left panel: predicted thickness (radius fraction, d) of the interior layers of TOI-771 b as computed with ExoMDN. The panel also features a sketch of the planet showing the radius fractions corresponding to the posterior distributions of the inner core, mantle, water layer, and gas envelope in dark grey, light grey, dark blue, and light blue, respectively. The total uncertainty on the planetary radius is shown with the dashed black outer rings, while the uncertainties on each layers thickness are shown by coloured rectangles. Right panel: predicted mass fraction (w) of the interior layers of TOI-771 b as computed with ExoMDN.
