Evolutionary Tracks and Observational Constraints
Abstract
We have performed stellar calculations for initial masses between 1 and 7 Modot from the main sequence through the AGB towards the stage of white dwarfs. Our calculations indicate that massive central stars fade much slower than hitherto assumed leading to the prediction that the least luminous central stars should have masses of 0.65 Modot. It is emphasized that post- AGB timescales depend strongly on the AGB history. Furthermore, we discuss the possibility of two thermal pulses during the post-AGB evolution.
