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…

On the distance of the globular cluster M4 (NGC 6121) using RR Lyrae stars: II. Mid-infrared period-luminosity relations
J. R. Neeley, M. Marengo, G. Bono +12
New mid-infrared period-luminosity (PL) relations are presented for \rrl{} variables in the globular cluster M4 (NGC 6121). Accurate photometry was obtained for 37 \rrl{} variables…

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…
