Notes. Mi: Initial mass of the model (at ZAMS). MWD: final WD mass. HeCF: Full He-core flash at the beginning of the core He-burning phase. τpre-WDMS: Lifetime from the ZAMS to the onset of WD cooling branch. : mass of the H-free core at the first thermal pulse (defined as those regions with XH < 10−4). MH: Mass of the H content at the maximum effective temperature at the beginning of the WD cooling branch. : mass of the H content at the ZZ Ceti instability strip. NC/NO: C/O ratio as a number fraction at the end of the TP-AGB phase.
