[Mesa-users] Requesting help with binary core-collapse modeling

[Jared Goldberg]

We'll need a bit more information on why the solver fails. Is the solver
failing because of mass transfer or some binary phenomenon? Which star is
failing? Is it the core or surface of the star that is having issues?

Also, on the setup: is there anything in run_star_extras or binary_extras?
(can you send a full working directory?)

PS -- if you're exploding stripped donors, note that the test_suite is
designed for a H-rich envelope and a lot of the steps involve tracking
where in the star the shock is relative to the He core. I'm happy to
correspond off-list (or on-list) about how to blow up stripped things with
a similar setup as ccsn_IIp.

Best,
~Jared
