Multiple populations in the old and massive Small Magellanic Cloud globular cluster NGC121
E. Dalessandro, E. Lapenna, A. Mucciarelli +3
We used a combination of optical and near-UV Hubble Space Telescope photometry and FLAMES/ESO-VLT high-resolution spectroscopy to characterize the stellar content of the old and ma…
Searching in the dark: the dark mass content of the Milky Way globular clusters NGC288 and NGC6218
A. Sollima, F. R. Ferraro, L. Lovisi +8
We present an observational estimate of the fraction and distribution of dark mass in the innermost region of the two Galactic globular clusters NGC 6218 (M12) and NGC 288. Such an…
Lost and found: evidence of Second Generation stars along the Asymptotic Giant Branch of the globular cluster NGC 6752
E. Lapenna, C. Lardo, A. Mucciarelli +7
We derived chemical abundances for C, N, O, Na, Mg and Al in 20 asymptotic giant branch (AGB) stars in the globular cluster NGC 6752. All these elements (but Mg) show intrinsic sta…
NLTE effects on AGB stars in 47 Tucanae
Emilio Lapenna, Alessio Mucciarelli, Barbara Lanzoni +4
We present the iron abundance of 24 asymptotic giant branch (AGB) stars members of the globular cluster 47 Tucanae, obtained with high-resolution spectra collected with the FEROS s…
