14. 3D Hydrodynamical Models of the Core Helium Flash

John Lattanzio (Monash University)

30/06/2006, 14:00

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.

60. The s-process in massive stars: the Shell C-burning contribution

Marco Pignatari (Universita' di Torino)

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...

22. Light and heavy elements nucleosynthesis in low mass AGB Stars

Sergio Cristallo (Osservatorio Astronomico Teramo (INAF, Italy))

30/06/2006, 14:40

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...
