Abstract (from CDS):
The derived dust mass-loss rates are in the range 5x10–10 to 3x10–8M☉/yr for the observed AGB stars in Sgr dSph and around 5x10–9M☉/yr for those in Fornax; while values obtained with the two different methods are of the same order of magnitude. The mass-loss rates for these stars are higher than the nuclear burning rates, so they will terminate their AGB phase by the depletion of their stellar mantles before their core can grow significantly. Some observed stars have lower mass-loss rates than the minimum value predicted by theoretical models.
