Wind Accretion in Massive Binaries Experiencing High Mass Loss Rates I. Dependency on Mass Ratio and Orbital Period

The dataset accompanying this study contains all essential components required to run the MESA (Modules for Experiments in Stellar Astrophysics) code for our numerical simulations investigating wind accretion in a binary system, as well as its dependence on orbital period and mass ratio. It includes a complete inlist file that defines the input physics, control parameters, and computational settings necessary for stellar evolution modeling. Additionally, the dataset provides the rn and mk files, which are used to compile the MESA source code and ensure proper execution on the user's system. The dataset also includes the run_star_extras.f90 file, along with key output files generated during the simulations—namely, history.data and profile.data. The history.data file records the star’s global parameters (e.g., luminosity, surface temperature, stellar radius, total mass, central entropy, and energy contributions) as functions of time. In contrast, the profile.data files provide detailed snapshots of the star’s internal structure at selected time steps, offering spatially resolved data on quantities such as density, temperature, chemical composition, and energy generation rates. To support data analysis and visualization, the dataset includes Python scripts that extract and plot key stellar parameters from the MESA outputs.
