This test case checks that the evolution of a 7 |Msun|, metal-poor Z = 0.001, model reaches the AGB.

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

* Part 1 (``inlist_start``) creates a pre-main sequence model.

* Part 2 (``inlist_7M_prems_to_AGB``) continues the evolution as core hydrogen and helium burning proceed, terminating when log10(L/Lsun)=4.3 is reached. The model executes a blue loop as helium depletes, with the red edge and blue edge of the classical Cepheid instability strip boundaries shown in the HR diagram:
