Multimodal atmospheric characterization of β Pictoris b: Adding high-resolution continuum spectra from GRAVITY

We present the first VLTI/GRAVITY observations at R~4000 of Beta Pic b. These four high S/N (~20) K-band spectra conserve both the pseudo-continuum and molecular absorption patterns. We analyze them with four self-consistent forward model grids (Exo-REM, ATMO, BT-Settl, Sonora) exploring Teff, log(g), metallicity, C/O, and, 12CO/13CO ratio. We also upgrade our forward modeling code ForMoSA to account for the data multi-modality and combine the GRAVITY epochs with published 1-5 µm photometry, low- to medium-resolution spectra (0.9-7 µm), and high-resolution echelle spectra (2.1-5.2 µm). This repository includes all the observations and a useful set of outputs from the inversion analyses, including best-fit models. A README file is included to document the file structure, units, and relevant references. You may also find an additional exemple.ipynb notebook to help you extract the data.
