Fig. 3


Mass-loss rates and luminosities derived from the DUSTY models fitting of the AGB star SEDs in our Galactic bulge sample. In cases where ranges of luminosities and mass-los rates are given in Table 3, we plot the average. Stars with envelopes of unknown chemistry are plotted with asterisks. The classical limit for mass-loss rates caused by radiation pressure on dust is shown by a dashed line, and the empirical mass-loss rate upper boundary for AGBs and red supergiants in the Large Magellanic Cloud found by van Loon et al. (1999) is plotted as a dotted line. Also the maximum luminosity achievable by AGB stars is marked by the vertical dash-dot line.
