Asteroseismic Signatures of Stellar Merger Simulations with MESA

Simulation data and run files from Rui and Fuller 2021, modeling stellar mergers using the Modules for Experiments in Stellar Astrophysics (MESA) software. The data includes inlists, run files, and selected output for single star models and various merger scenarios between red giants and main sequence stars. The work was authored by Nicholas Z. Rui of the California Institute of Technology.

Use Cases

• Training or validating stellar evolution models based on the provided MESA simulation outputs.
• Analyzing asteroseismic signatures of post-merger stars based on the described stellar profile data.
• Comparing different stellar merger scenarios (e.g., red giant + main sequence, main sequence + main sequence) based on the categorized simulation directories.
• Reproducing or extending the results of the cited paper using the included inlist and run files.

Strengths

• Includes the specific MESA version (r12778) used for reproducibility.
• Data is organized into specific subdirectories (e.g., single, rg+ms, ms+ms) corresponding to distinct simulation scenarios described in the paper.
• Provides modified source code (run_star_extras.f) for modeling stellar mergers.

Limitations

• Row count and total data size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred from the MESA output files after download.
• Last update date is unknown; freshness unverified.
