Top panel: Exo-REM [M/H] predictions (dashed black lines) based on three inversions: GRAVITY with continuum (0.82 ± 0.02), GRAVITY without continuum (0.24 ± 0.12), and all datasets combined (0.50 ± 0.01). Colored regions show simulated population predictions from Schneider&Bitsch (2021a) center around the predicted mass (5 M_Jup ≤ M ≤ 15 M_Jup) and semi-major axis (5 au ≤ a ≤ 15 au) for β Pic b: in yellow are planets form if the disk is plain (i.e., no evaporation and condensation), while in blue are planets form when the full model is included. Bottom panel: similar to the top panel, but for C/O predictions. All Exo-REM predictions cluster near C/O ∼ 0.55, so only one dashed line is shown. Dashed blue and red lines mark the maximum C/O values explored by Exo-REM and BT-Settl, respectively.
