| Abstract | We use the combination of photometric and spectroscopic data of 47 Tuc stars to reconstruct the possible formation of a second generation of stars in the central regions of the cluster, from matter ejected by massive asymptotic giant branch (AGB) stars diluted with pristine gas. The yields from massive AGB stars with the appropriate metallicity (Z = 0.004, i.e. [Fe/H] = -0.75) are compatible with the observations in terms of extension and slope of the patterns observed, involving oxygen, nitrogen, sodium and aluminium (...) we estimate that the initial first-generation population in 47 Tuc was about 7.5 times more massive than the cluster current total mass. |
