We briefly summarize the impact of the chemical peculiarities associated to the multiple population phenomenon in Galactic Globular Clusters, on the evolutionary prop- erties

Abstract. This paper is aimed at emphasizing some of the main hints, constraints and dif- ficulties we currently have in trying to understand how globular clusters formed, along

Due to the radiative lev- itation effects (that alter the surface chemical abundances of BSSs hotter than ∼7800-8000 K, see Lovisi et al. 2012), reliable upper limits for the

How does this number compare to the duty cycle of the most common DNe among the intrinsic CV population. As already noted above, theory predicts that the vast majority of CVs should

If one increases the mass loss on the red gi- ant branch beyond the value required for the hottest extreme HB stars, however, the result is not a hotter EHB star, but a

Such an evolutionary channel predicts that red giant stars undergoing violent mass-loss events ap- proach the tip of the red giant branch with a total mass that is too small for

The recently discovered globular clusters can be classified into two groups: (1) low galactic latitude, very reddened globular clus- ters, and (2) very low surface brightness
