We present new synthetic stellar models for the thermally-pulsing asymptotic giant branch (TP-AGB) phase of low- and intermediate-mass stars. These models are particularly suitable for population synthesis studies, as they i) cover the whole mass range of interest (0.8-5.0 M_{sun}), ii) span a wide range in metallicity (0.0001 ≤ Z ≤ 0.03), iii) include several important improvements in the adopted input physics (e.g.variable molecular opacities), and iv) are calibrated on basic observables so as to provide a realistic description of the contribution from AGB stars to both resolved and integrated properties of galaxies.

Abstract
We present new synthetic stellar models for the thermally-pulsing asymptotic giant branch (TP-AGB) phase of low- and intermediate-mass stars. These models are particularly suitable for population synthesis studies, as they i) cover the whole mass range of interest (0.8-5.0 M_{sun}), ii) span a wide range in metallicity (0.0001 ≤ Z ≤ 0.03), iii) include several important improvements in the adopted input physics (e.g.variable molecular opacities), and iv) are calibrated on basic observables so as to provide a realistic description of the contribution from AGB stars to both resolved and integrated properties of galaxies.
