This test case shows an example of making a 0.4 Msun, Z=0.02 metallicity, helium model - a B-type subdwarf (sdB) star.
This test case has 1 part. Click to see a larger version of a plot.
- Part 1 (
inlist_make_sdb) first loads a prebuilt helium core model
start_core_he_burn.modthat comes from the 1M_pre_ms_to_wd test case (specifically
inlist_to_end_core_he_burnis modified to stop when the mass fraction of helium dropes below 0.95). Then the hydrogen envelope is removed with
relax_initial_mass_to_remove_H_env = .true.as a model for a common envelope event removal of the envelope. The model is then evolved until the mass fraction of carbon rises above 0.05 :
