| Abstract: |
Preliminary results from an ongoing project to compute a grid of post-AGB
models is presented. Our preliminary results show that stellar evolution
computations that include an updated treatment of the microphysics predict
post-AGB timescales that are several times shorter that predicted by older
models. Also the mass-luminosity relation of post-AGB models deviates from
that of older grids. In addition, our results suggest only a slight
metallicity dependence of the post-AGB timescales. We expect these results to
have significant consequences for models of the formation of planetary
nebulae and their luminosity function. |
