The soundtrack of RR Lyrae in Omega Cen at high-frequency
A. Calamida, S. K. Randall, M. Monelli +8
We present preliminary Sloan u',g'-band light curves for a sample of known RR Lyrae variables in the Galactic globular cluster Omega Cen. Results are based on the partial reduction…
NGC5694: another extra-galactic globular cluster
A. Mucciarelli, M. Bellazzini, M. Catelan +5
We discuss the chemical composition of six giant stars of the outer Halo globular cluster NGC5694, through the analysis of UVES@FLAMES high-resolution spectra. The cluster has an a…
Multiple populations in Galactic globular clusters: a survey in the Strömgren system
J. Alonso-García, M. Catelan, P. Amigo +10
We are coming to believe that stellar populations in globular clusters are not as simple as they were once thought to be. A growing amount of photometric and spectroscopic evidence…
Theoretical Modeling of the RR Lyrae Variables in NGC 1851
Andrea Kunder, Maurizio Salaris, Santi Cassisi +5
The RR Lyrae instability strip (IS) in NGC 1851 is investigated, and a model is presented which reproduces the pulsational properties of the RR Lyrae population. In our model, a st…
