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…

NGC1866: New analysis from HST-WFPC2 observations of the inner regions

E. Di Carlo, G. Raimondo, E. Brocato +2

We report new results on the LMC globular cluster NGC 1866 obtained by analyzing F555W and F814W images from WFPC2@HST. On the basis of the CMD we derive information on the cluster…

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…

Surface Brightness Fluctuations: a theoretical point of view

M. Cantiello, G. Raimondo, E. Brocato +1

We present new theoretical evaluations of optical and near-IR Surface Brightness Fluctuations (SBF) magnitudes for single-burst stellar populations in the age range t=5-15 Gyr and…

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…
