First full evolutionary computation of the He-flash induced mixing in Population II stars
S. Cassisi, H. Schlattl, M. Salaris +1
The core helium-flash in low-mass stars with extreme mass loss occurs after the tip of the RGB, when the H-rich envelope is very thin. The low efficiency of the H-shell source enab…

Some clues on the tilt of the Horizontal Branches in metal-rich clusters
G. Raimondo, V. Castellani, S. Cassisi +2
We discuss some clues on the large tilt observed in the Horizontal Branch of the metal-rich galactic globular clusters NGC 6388 and NGC 6441. This not yet understood feature is inv…

The surface carbon and nitrogen abundances in models of ultra metal-poor stars
H. Schlattl, M. Salaris, S. Cassisi +1
We investigate whether the observed high number of carbon- and nitrogen-enhanced extremely metal-poor stars could be explained by peculiar evolutionary properties during the core H…
