JWST high-contrast spectroscopy with speckle modelling: Atmospheric retrievals of the T-dwarf companion HD 19467 B

Context. High-contrast medium-resolution spectroscopy with JWST can resolve molecular and isotopic features in cool substellar atmospheres, but for close-in companions, the extracted spectra can be biased by wavelength-dependent residual stellar contamination. Aims. We assess the impact of residual...
