The Carina Project IX: on Hydrogen and helium burning variables
G. Coppola, M. Marconi, P. B. Stetson +14
We present new multi-band (UBVI) time-series data of helium burning variables in the Carina dwarf spheroidal galaxy. The current sample includes 92 RR Lyrae-six of them are new ide…

The Carina Project. VIII. The α-element abundances
M. Fabrizio, M. Nonino, G. Bono +16
We have performed a new abundance analysis of Carina Red Giant (RG) stars from spectroscopic data collected with UVES (high resolution) and FLAMES/GIRAFFE (high and medium resoluti…

On a new theoretical framework for RR Lyrae stars I: the metallicity dependence
M. Marconi, G. Coppola, G. Bono +7
We present new nonlinear, time-dependent convective hydrodynamical models of RR Lyrae stars computed assuming a constant helium-to-metal enrichment ratio and a broad range in metal…
