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…
Multiple stellar populations in Magellanic Cloud clusters. III. The first evidence of an extended main sequence turn-off in a young cluster: NGC1856
A. P. Milone, L. R. Bedin, G. Piotto +7
Recent studies have shown that the extended main-sequence turn off (eMSTO) is a common feature of intermediate-age star clusters in the Magellanic Clouds (MCs). The most simple exp…
The evolutionary properties of intermediate-mass stars
S. Cassisi
We briefly review the main problems related to the computation of the evolution of intermediate-mass stars: the treatment of turbulent convection and the occurrence of blue loops d…
On the White Dwarf distances to Galactic Globular Clusters
M. Salaris, S. Cassisi, E. Garcia-Berro +2
We analyze in detail various possible sources of systematic errors on the distances of globular clusters derived by fitting a local template DA white dwarf sequence to the cluster…
HST observations of the LMC field around SN87A: distance determinations with Red Clump and Tip of the Red Giant Branch stars
Martino Romaniello, Maurizio Salaris, Santi Cassisi +1
We have used HST-WFPC2 multiband observations of a field around SN 1987A in the Large Magellanic Cloud to measure its distance from the Sun. The observations allowed us to carefull…
