MESAlab: A Python pipeline for MESA grid processing with integrated GYRE/MESA-RSP execution

Abstract

Modules for Experiments in Stellar Astrophysics (MESA) is a widely used open-source code for modeling stellar evolution. Many applications of the code rely on large computational grids containing thousands of models, which can be time-consuming to analyze. The mesalab package was developed to automate this post-processing. This Python-based, modular pipeline supports the analysis of large MESA grid outputs and can identify selected evolutionary features, such as the blue loop phase of the evolution of classical Cepheids. The pipeline can automatically prepare input files for and launch MESA-RSP and GYRE to investigate the pulsation properties associated with these evolutionary phases. The pipeline also includes tools for visualizing evolutionary tracks, including Hertzsprung-Russell diagrams and Gaia color-magnitude diagrams.
