wd_cool_0.6M

This test case the checks the evolution of a cooling, element diffusing 0.6 Msun white dwarf.

This test case has 1 part. Click to see a larger version of a plot.

  • Part 1 (inlist_relax_mass) loads co_wd_settled.mod, a 0.596 Msun carbon-oxygen white dwarf model with hydrogen-rich outer layers, produced from final.mod produced by make_co_wd as of version 14731 :

The evolution then commences with element diffusion activated, and the run terminates when the central temperature drops below 1e6 K:
