[Mesa-users] Small timesteps in binary evolution towards LMXB formation

[Ebraheem Farag]

Hello Ndiogou,

Your inlists are pretty barebones. You might need to add some additional
inlist options from something like
$MESA_DIR/star/test_suite/20M_pre_ms_to_core_collapse to get your model to
get that 13 Msun model past Oxygen burning.

Timesteps, op_split_burn, probably turning on hydro (v_flag) for core
collapse. See 'inlist_common' and 'inlist_to_cc' in
$MESA_DIR/star/test_suite/20M_pre_ms_to_core_collapse.
