Uncertaities due to convection and production of s-nuclei in massive stars
M. L. Pumo, G. Contino, A. Bonanno +1
We have investigated the role of the convective overshooting on the production of s-nuclei during core He-burning phase in stellar models with different initial mass and metallicit…
Convective overshooting and production of s-nuclei in massive stars during their core He-burning phase
M. L. Pumo, G. Contino, A. Bonanno +1
With the "post-processing" technique we explore the role of the convective overshooting on the production of s-nuclei in stellar models of different initial mass and metallicity ($…
The "double final fate" of super-AGB stars and its possible consequences for some astrophysical issues
M. L. Pumo, P. Ventura, F. D'Antona +1
Super-AGB stars can conclude their evolution either as neon-oxygen white dwarfs or as electron-capture supernovae. We discuss the possible consequences of the existence of this "do…
Super-AGB stars: evolution and associated nucleosynthesis
M. L. Pumo, L. Siess, R. A. Zappala'
Based on evolutionary computations of 90 stellar models, we have analysed the impact of initial composition and core overshooting on the post-He-burning evolution and the associate…
Sources of uncertainties in the s-process in massive stars: convection and reaction rates
V. Costa, M. L. Pumo, A. Bonanno +1
Current models of s-nucleosynthesis in massive stars ( to ) are able to reproduce some main features of the abundance distributions of heavy i…
A search for very young Planetary Nebulae
G. Umana, L. Cerrigone, C. Trigilio +1
Despite numerous efforts, the transition from Asymptotic Giant Branch (AGB) stars to Planetary Nebulae (PN) is a poorly understood phase of stellar evolution. We have therefore car…
The synthesis of the light Mo and Ru isotopes: how now, no need for an exotic solution ?
V. Costa, M. Rayet, R. A. Zappalà +1
The most detailed calculations of the p-process call for its development in the O/Ne layers of Type II supernovae. In spite of their overall success in reproducing the solar system…
