Caption: Figure 10.
Transitions in stellar physics lead to non-monotonic Minit–age relations in (at least) two cases. This figure demonstrates two cases where non-monotonicity occurs. Both panels show the Minit–age relations of three successive EEPs, denoted by different colors; the first and last EEPs (orange and green, respectively, in both panels) exhibit normal, monotonic behavior. The intermediate EEP (blue) exhibits non-monotonic behavior. Left: the transition from radiative to convective core on the MS. Right: the transition between degenerate and non-degenerate onset of core He burning (Girardi et al. 2013). Both panels show a sequence of EEPs during which the non-monotonic behavior appears. The dashed horizontal lines in each panel indicate isochrone ages for which multiple stars would appear in the same EEP (if allowed to).
