Atmospheric evolution through outgassing and escape on young molten rocky exoplanets

This upload contains the data, figures, and plotting scripts associated with our paper on atmospheric evolution via outgassing and escape on young molten rocky exoplanets, submitted to Astronomy & Astrophysics in February 2026. Included are simulations performed with and without atmospheric escape, using the JANUS or AGNI atmospheric modules. This dataset does not include all individual simulations generated by the PROTEUS code for the 0.194 Msun and 1 Msun grids used in this study. For the grid study, we provide only 2 csv files (one for each stellar type), which contain all input parameters for each case along with the corresponding final outputs. The table below presents the repository structure, showing the main data, figures, and scripts included in this upload.
