1M_pre_ms_to_wd

This test case checks the evolution of a 1 Msun, Z=0.02 metallicity from the pre-main sequence to a white dwarf.

This test case has six parts. Click to see a larger view of a plot.

  • Part 1 (inlist_start_header) builds a 1 Msun, Z=0.02 metallicity pre-main-sequence model.

  • Part 2 (inlist_to_end_core_h_burn) continues the evolution until core hydrogen depletion (mass fraction h1_center < 1e-4).

  • Part 3 (inlist_to_start_he_core_flash_header) continues the evolution until the onset of core helium ignition (power from he burning > 10).

  • Part 4 (inlist_to_end_core_he_burn) continues the evolution until core helium depletion (mass fraction he4_center < 1e-4).

  • Part 5 (inlist_to_end_agb) continues the evolution through the thermal pulses until the end of the AGB phase of evolution (hydrogen-rich envelope mass < 1e-2 Msun).

  • Part 6 (inlist_to_wd) continues the evolution until the luminosity of the cooling white dwarf reaches L < 0.1 Lsun.
