| 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. |
