摘要：
We explore whether the systematic difference between asteroseismological and spectroscopic masses in PG 1159-type stars can be understood in terms of uncertainties in mass-loss rates and/or third dredge-up efficiencies in the TP-AGB. We find that neither of them can account for the discrepancy.
