Posterior distributions of key parameters from our atmospheric retrievals with (blue) and without (orange) informed stellar heterogeneity priors, as well as the best-fit pressure–temperature profile. The blue dotted lines illustrate the normal priors applied to fhet, Thet, and Tphot for the run with informed priors. The black line in the Mp panel represents the dynamical mass constraint of J. H. Livingston et al. (2026) for comparison.
