Atmospheric temperature profiles for TWA 27A (a) and TWA 28 (b). Left panels: retrieved profiles from JWST/NIRSpec observations (G140H+G235H+G395H, blue lines) and excluding G140H (green lines), with 1-, 2-, and 3σ confidence intervals (shaded regions). CRIRES+ profile for TWA 28 (González Picos et al. 2024) and a cloud-less Sonora Diamondback model at Teff = 2400 K, log g = 4.0 (Morley et al. 2024) are shown for comparison. Right panels: residuals between median G140H+G235H+G395H profiles and other datasets.
