## Example Directories

**work:** Contains inlists, run\_star\_extras, and run\_binary_\extras needed to reproduce our results. These were adapted from the reproduction package of A&A 650, A107 (2021). A small number of models did not converge using the default controls. These can be made to complete by either setting the control make\_gradr\_sticky\_in\_solver\_iters = .true. (see inlist1, this works for models with small initial periods) or by relaxing delta\_HR\_limit and delta\_HR\_hard\_limit (see run\_binary\_extras line 900).
