The Cepheids of NGC1866: A Precise Benchmark for the Extragalactic Distance Scale and Stellar Evolution from Modern UBVI Photometry
I. Musella, M. Marconi, P. B. Stetson +8
We present the analysis of multiband time-series data for a sample of 24 Cepheids in the field of the Large Magellanic Cloud cluster NGC1866. Very accurate BVI VLT photometry is co…
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 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…
STREGA: STRucture and Evolution of the GAlaxy. I. Survey Overview and First Results
M. Marconi, I. Musella, M. Di Criscienzo +28
STREGA (STRucture and Evolution of the GAlaxy) is a Guaranteed Time survey being performed at the VST (the ESO VLT Survey Telescope) to map about 150 square degrees in the Galactic…
The Carina Project. VI. The helium burning variable stars
G. Coppola, P. B. Stetson, M. Marconi +14
We present new optical (BVI) time-series data for the evolved variable stars in the Carina dwarf spheroidal galaxy. The quality of the data and the observing strategy allowed us to…
RR Lyrae the Stellar Beacons of the Galactic Structure
Giuseppe Bono, Massimo Dall'Ora, Filippina Caputo +5
We present some recent findings concerning the use of RR Lyrae as distance indicators and stellar tracers. We outline pros and cons of field and cluster RR Lyrae stars and discuss…
