Deep FORS1 observations of the double Main Sequence of omega Centauri
A. Sollima, F. R. Ferraro, M. Bellazzini +3
We present the results of a deep photometric survey performed with FORS1@VLT aimed at investigating the complex Main Sequence structure of the stellar system omega Centauri. We con…

The RR Lyrae Period - K Luminosity relation for Globular Clusters: an observational approach
A. Sollima, C. Cacciari, E. Valenti
The Period - metallicity - K band luminosity (PLK) relation for RR Lyrae stars in 15 Galactic globular clusters and in the LMC globular cluster Reticulum has been derived. It is ba…

New Metallicities of RR Lyrae Stars in omega Centauri: Evidence for a Non He-Enhanced Metal-Intermediate Population
A. Sollima, J. Borissova, M. Catelan +4
We present new spectroscopic metal abundances for 74 RR Lyrae stars in omega Cen obtained with FLAMES. The well-known metallicity spread is visible among the RR Lyrae variables. Th…
