Evolution of accretor stars in massive binaries: broader implications from modeling ζ Ophiuchi

Input and output files for MESA r15140 described in Renzo & Gotberg 2021. We used the MESA SDK x86_64-linux-20.12.1. `fiducial.tar.xz` contains the MESA work directories and output for the evolution of the model described in Sec. 3, one for the evolution in a binary, and one after detachment to finish the main sequence of the accreting star. `single_stars.tar.xz` contains rotating single star models labeled according to their initial mass, and for each mass non-rotating (no-rot) and rotating models (labelled based on the initial omega/omega_crit) are provided. The other tarballs contain structures similar to `best_model.tar.gz` with parameter variations (see Sec. 6 and README.org). All parameter variations described in the paper can be obtained by modifying one (or more) parameters from the input files contained in these folders. A git repository for this project is available on github
