Abstract
Asymptotic Giant Branch (AGB) stars are among the major polluters of the interstellar medium. These objects produce both light (C, N, O, F, Na) and heavy elements (via the slow neutron capture process, the s-process). We have devoted a long-standing project to study the physical and chemical properties of AGB stars. Our models are available on the on-line FRUITY database, which currently provides the surface isotopic compositions and yields from hydrogen to lead of low-mass AGB stars (1.3 ≤ M/M☉ ≤ 3.0). We present a new set of intermediate-mass AGB models (4.0, 5.0 and 6.0 M☉ with -2.15 ≤ [Fe/H] ≤ +0.15). We discuss their physical and chemical properties, highlighting the differences with respect to the set already on-line. Moreover, we check the reliability of our models by comparing them to observed quantities, such as the initial-to-final mass relation and AGB luminosity functions.
