Element production, stellar evolution and stellar explosions
Oral contribution
We present fully three dimensional models of the core helium flash in low mass stars.
These hydordynamical models show that the simple 1D hydrostatic models are not too
misleading! New results, for rotating models, will be reported.

Element production, stellar evolution and stellar explosions
Oral contribution
In massive stars evolution the s-process is activated at different temperatures,
during He-burning and during C-burning.
In the convective C Shell, the s-process affects the previous Core He-burning s
yields, and the final results carry the signature of both the two following neutron
capture processes.
A detailed analysis of the s-process in massive stars is presented, in particular...

Element production, stellar evolution and stellar explosions
Oral contribution
We present a new set of low mass AGB Stars models having the same mass (2 Msun) and
different metallicities (Z=1e-4, Z=e-3 and Z=1.5e-2, corresponding to the most
recent evaluation of the solar metallicity).
For each mass we present the evolution from the Pre Main Sequence up to the end of
the Thermally Pulsing AGB Phase.
The introduction of an exponential decay of the convective...
