star_plus_point_mass
This test case checks the evolution of one star plus a point mass, including mass transfer to the point mass.
This test case has 1 part. Click to see a larger version of a plot.
Part 1 (
inlist_project
) loads a pre-built 5 Msun zero-age main sequence model as the donor and a 10 Msun point mass as the companion. The binary system has an initial period of 1 day, and is evolved until the central hydrogen mass fraction of the donor drops below 1e-2. Compare the evolutions bewlow with those in star_plus_point_mass_explicit_mdot.
