Simultaion of Pre-Supernova Multiple Giant Eruptions in Massive Stars

The dataset accompanying this study includes all essential components required to execute the MESA (Modules for Experiments in Stellar Astrophysics) code for our numerical simulations focused on accretion mechanics in massive stars. It features a complete inlist file that specifies all the input physics, control parameters, and computational settings necessary for the stellar evolution modeling. Also included are the rn and mk files, which are critical for compiling the MESA source code and ensuring proper code functionality on the user's system. The dataset further provides comprehensive history.data and profile.data files generated during the simulations. The history.data file records the global stellar parameters (such as luminosity, surface temperature, stellar radius, total mass, central entropy, and various forms of energy) as functions of time, while the profile.data files store internal structure data at selected time steps offering spatial resolution for variables such as density, temperature, composition, and energy generation rates throughout the star's interior. To facilitate visualization and analysis, the dataset includes Python scripts designed to extract and plot key parameters from the MESA output. These scripts generate graphs that track the evolution of stellar properties over time and with radius, supporting a detailed understanding of the physical processes occurring during MGEs.
