Identifier: http://hdl.handle.net/1959.14/1066690
Description: We used FLAMES+GIRAFFE (Medusa mode) at the VLT to obtain moderately high resolution spectra for 30 red horizontal branch (RHB) stars, 4 RR Lyrae variables, and 17 blue horizontal branch (BHB) stars i ... More

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/1959.14/299643
Description: We discuss a variety of photometric indices assembled from the uvby Strömgren system. Our aim is to examine the pros and cons of the various indices to find the most suitable one(s) for studying the p ... More

Identifier: http://hdl.handle.net/1959.14/299782
Description: ω Centauri, the largest globular cluster of the Milky Way, is composed of several stellar populations, which can be seen in both photometry and spectroscopy. The history of how these different populat ... More

Identifier: http://hdl.handle.net/1959.14/300046
Description: Homogeneous abundances of light elements, a-elements, and Fe-group elements from high-resolution FLAMES spectra are presented for 76 red giant stars in NGC 6715 (M 54), a massive globular cluster (GC) ... 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
