MESAlab: a Pipeline for Mapping the Blue Loop with MESA runs (2509.08946v1)

Abstract: Modules for Experiments in Stellar Astrophysics (MESA; (Paxton2011, 2013, 2015, 2018, 2019, Jermyn 2023) is a widely used open-source software for modelling stellar evolution. In many studies, the computational grids covers thousands of models (e.g., Joyce et al 2024), which requires a tremendous amount of time and computational effort to process. To streamline data analysis, the mesalab package was developed. This Python-based pipeline is designed to simplify the post-processing of MESA outputs by automatically identifying various stellar evolutionary phases, with a specific focus on the blue loop'' -- a blue-ward excursion in the Hertzsprung-Russell Diagram (HRD) for intermediate-mass stars often associated with peculiar pulsational phenomena likestrange modes.''
