We present a new grid of stellar model calculations for stars on theAsymptotic Giant Branch between 1.0 and .Our grid consists of 10 chemical mixtures with 5 metallicities between Z=0.0005and Z=0.04, and with both solar-like and -elementenhanced metal ratios for each metallicity. We treat consistently thecarbon-enhancement of the stellar envelopes by using opacity tableswith varying C/O-ratio and by employing theoretical mass loss rates forcarbon stars. The low temperature opacities have been calculatedspecifically for this project. For oxygen stars we use an empiricalmass loss formalism. The third dredge-up is naturally obtained byincluding convective overshooting. Our models reach effectivetemperatures in agreement with earlier synthetic models, which includedapproximative carbon-enriched molecular opacities and show goodagreement with empirically determined carbon-star lifetimes. A fractionof the models could be followed into the post-AGB phase, for which weprovide models in a mass range supplementing previous post-AGBcalculations. Our grid constitutes the most extensive set ofAGB-models, calculated with the latest physical input data and treatingcarbon-enhancement due to the third dredge-up most consistently.Key words: stars: evolution - stars: AGBand post-AGB - stars: interiors
