COSMIC-METISSE EEP Files: Stellar Evolution Tracks for Four Models

Four model tarballs, each about 900Mb, contain EEP files for running the COSMIC-METISSE stellar evolution code. Each unpacked directory, totaling about 3.6Gb, includes separate 'hydrogen' and 'helium' track folders. The data is from Maclean et al., 2026, and was last updated on 2026-06-29.

Use Cases

• Simulate binary star system evolution based on the provided stellar evolution tracks.
• Compare stellar outcomes using the four different physical models (standard, new CBM, new winds, new winds+new CBM).
• Initialize population synthesis studies by setting path variables to the hydrogen and helium track folders.

Strengths

• Provides four distinct physical models for stellar evolution, allowing for comparative studies.
• Each model's data is packaged in a self-contained tarball of about 900Mb with a clear folder structure.
• Includes explicit citation instructions linking the data to the originating 2026 research paper.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific file formats for the underlying track data are unknown.
• Description metadata is limited; actual data quality and structure require manual inspection after download.
