Identifier: http://hdl.handle.net/1959.14/359625
Description: We present the abundance analysis of 82 red giant branch stars in the dense, metal-poor globular cluster NGC 6093 (M 80), the largest sample of stars analysed in this way for this cluster. From high-r ... More

Identifier: http://hdl.handle.net/1959.14/300062
Description: The stars in a globular cluster (GC) have always been considered coeval and of the same metallicity. Recently, this assumption has been challenged on the basis of spectroscopic and photometric observa ... More

Identifier: http://hdl.handle.net/1959.14/300406
Description: We study the radial distribution of stars from different stellar generations in the globular cluster NGC 3201. From recently published multicolour photometry, a radial dependence of the location of st ... More
