Identifier: http://hdl.handle.net/1959.14/261805
Description: We present aluminium abundances for a sample of about 100 red giant stars in each of the Galactic globular clusters 47 Tuc (NGC 104) and M 4 (NGC 6121). We have derived homogeneous abundances from int ... More

Identifier: http://hdl.handle.net/1959.14/274639
Description: We obtained FLAMES GIRAFFE+UVES spectra for both first- and second-generation red giant branch (RGB) stars in the globular cluster (GC) NGC 362 and used them to derive abundances of 21 atomic species ... More

Identifier: http://hdl.handle.net/1959.14/185997
Description: We studied the distribution of aluminum abundances among red giants in the peculiar globular cluster NGC 1851. Aluminum abundances were derived from the strong doublet Al i 8772-8773 Ãmeasured on inte ... More

Identifier: http://hdl.handle.net/1959.14/299838
Description: We present a detailed chemical tagging of individual stellar populations in the Galactic globular cluster (GC) NGC 1851. Abundances are derived from FLAMES spectra for the largest sample of giants (12 ... More

Identifier: http://hdl.handle.net/1959.14/299887
Description: Globular clusters have been recognized to host multiple stellar populations. A spectacular example of this is the massive cluster NGC 2808, where multiple populations have been found along the horizon ... More

Identifier: http://hdl.handle.net/1959.14/299983
Description: We present the abundance analysis of a sample of more than 120 red giants in the globular cluster (GC) NGC 1851, based on FLAMES spectra. We find a small but detectable metallicity spread. This spread ... More

Identifier: http://hdl.handle.net/1959.14/299990
Description: The determination of the Ba abundance in globular cluster (GC) stars is a very powerful test to address several issues in the framework of multiple population scenarios. We measured the Ba content for ... More

Identifier: http://hdl.handle.net/1959.14/300200
Description: We present the first chemical composition study of two unevolved stars in the globular cluster NGC 2808, obtained with the X-shooter spectrograph at VLT. NGC 2808 shows three discrete, well-separated ... More
