The Carina Project. X. On the kinematics of old and intermediate-age stellar populations
M. Fabrizio, G. Bono, M. Nonino +14
We present new radial velocity (RV) measurements of old (horizontal branch) and intermediate-age (red clump) stellar tracers in the Carina dwarf spheroidal. They are based on more…
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…
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…
On the distance of the globular cluster M4 (NGC 6121) using RR Lyrae stars: I. optical and near-infrared Period-Luminosity and Period-Wesenheit relations
V. F. Braga, M. Dall'Ora, G. Bono +16
We present new distance determinations to the nearby globular M4 (NGC~6121) based on accurate optical and Near Infrared (NIR) mean magnitudes for fundamental (FU) and first overton…
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…
Variable stars in the ultra-faint dwarf spheroidal galaxy Ursa Major I
Alessia Garofalo, Felice Cusano, Gisella Clementini +6
We have performed the first study of the variable star population of Ursa Major I (UMa I), an ultra-faint dwarf satellite recently discovered around the Milky Way by the Sloan Digi…
Stellar Archaeology in the Galactic halo with Ultra-Faint Dwarfs: VII. Hercules
Ilaria Musella, Vincenzo Ripepi, Marcella Marconi +13
We present the first time-series study of the ultra-faint dwarf galaxy Hercules. Using a variety of telescope/instrument facilities we secured about 50 V and 80 B epochs. These dat…
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…
Distance to Galactic globulars using the near-infrared magnitudes of RR Lyrae stars: IV. The case of M5 (NGC5904)
G. Coppola, M. Dall'Ora, V. Ripepi +6
We present new and accurate near-infrared (NIR) J, K-band time series data for the Galactic globular cluster (GC) M5 = NGC5904. Data were collected with SOFI at the NTT (71 J + 120…
Sersic galaxy with Sersic halo models of early-type galaxies: a tool for N-body simulations
G. Coppola, F. La Barbera, M. Capaccioli
We present spherical, non-rotating, isotropic models of early-type galaxies with stellar and dark-matter components both described by deprojected Sersic density profiles, and prove…
The SDSS-UKIDSS Fundamental Plane of Early-type Galaxies
F. La Barbera, G. Busarello, P. Merluzzi +3
We derive the Fundamental Plane (FP) relation for a sample of 1430 early-type galaxies in the optical (r band) and the near-infrared (K band), by combining SDSS and UKIDSS data. Wi…
