Properties of binary systems in a one-dimensional approximation

We present numerically obtained tables of properties of stars in a binary system as a function of the effective potential:  volume-equivalent radii of the equipotential surfaces, effective accelerations averaged over the same equipotential surfaces and the properties of the L1 plane cross-sections. The tables are obtained for binaries where the ratios of the primary star mass to the companion star mass are from 10-6 to 105 and include equipotential surfaces up to the star's outer Lagrangian point. We supply a sample code showing how to use our tables to get the average effective accelerations in one-dimensional stellar codes.

Updates will be available at https://github.com/AliPourmand/1D_binary_star_properties. Paper describing the tables can be found on ApJ, DOI 10.3847/1538-4357/acd4c1, https://iopscience.iop.org/article/10.3847/1538-4357/acd4c1 If you make use of the provided tables or the code, we ask you to cite the paper (and zenodo deposit if such reference is allowed).
