Fig. 12.


Ages derived from interpolation of the full H-rich sample (213 objects, see Fig. 10) with the Z = 0.01 model grid of Miller Bertolami (2016). Upper panel: masses derived from interpolation in the HR diagram. Lower panel: masses derived from interpolation in the Kiel diagram (log g − log Teff). The vertical dashed line indicates the canonical value of 30 Kyr value beyond which PNe are not expected to survive.
