A theoretical scenario for Galactic RR Lyrae in the Gaia database: constraints on the parallax offset
Marcella Marconi, Roberto Molinaro, Vincenzo Ripepi +5
On the basis of an extended set of nonlinear convective RR Lyrae pulsation models we derive the first theoretical light curves in the Gaia bands and the corresponding intensity-wei…
The VMC Survey -- XXXVII. Pulsation periods of dust enshrouded AGB stars in the Magellanic Clouds
M. A. T. Groenewegen, A. Nanni, M. -R. L. Cioni +9
(abridged)Variability is a key property of stars on the asymptotic giant branch (AGB). Their pulsation period is related to the luminosity and mass-loss rate of the star. The long-…
The VMC Survey - XXXIII. The tip of the red giant branch in the Magellanic Clouds
M. A. T. Groenewegen, M. -R. L. Cioni, L. Girardi +6
In this paper JK_s data from the VISTA Magellanic Cloud (VMC) survey are used to investigate the tip of the red giant branch (TRGB) as a distance indicator. A linear fit to recent…
On a new method to estimate distance, reddening and metallicity of RR Lyrae stars using optical/near-infrared (,,,,,) mean magnitudes: Centauri as a first test case
G. Bono, G. Iannicola, V. F. Braga +26
We developed a new approach to provide accurate estimates of metal content, reddening and true distance modulus of RR Lyrae stars (RRLs). The method is based on homogeneous optical…
Gaia Data Release 1 - The Cepheid & RR Lyrae star pipeline and its application to the south ecliptic pole region
G. Clementini, V. Ripepi, S. Leccia +24
We present an overview of the Specific Objects Study (SOS) pipeline developed within the Coordination Unit 7 (CU7) of the Gaia Data Processing and Analysis Consortium (DPAC), the c…
On the RR Lyrae stars in globulars: IV. Centauri Optical UBVRI Photometry
V. F. Braga, P. B. Stetson, G. Bono +31
New accurate and homogeneous optical UBVRI photometry has been obtained for variable stars in the Galactic globular Cen (NGC 5139). We secured 8202 CCD images covering a time i…
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. 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 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…
The VMC ESO Public Survey
M. -R. L. Cioni, P. Anders, G. Bagheri +31
The VISTA near-infrared YJKs survey of the Magellanic Clouds system (VMC) has entered its core phase: about 40% of the observations across the Large and Small Magellanic Clouds (LM…
STEP: The VST survey of the SMC and the Magellanic Bridge. I. Overview and first results
V. Ripepi, M. Cignoni, M. Tosi +23
STEP (the SMC in Time: Evolution of a Prototype interacting late-type dwarf galaxy) is a Guaranteed Time Observation survey being performed at the VST (the ESO VLT Survey Telescope…
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…
CORS Baade-Wesselink distance to the LMC NGC 1866 blue populous cluster
R. Molinaro, V. Ripepi, M. Marconi +6
We used Optical, Near Infrared photometry and radial velocity data for a sample of 11 Cepheids belonging to the young LMC blue populous cluster NGC 1866 to estimate their radii and…
CoRoT\,102699796, the first metal-poor Herbig Ae pulsator: a hybrid Sct- Dor variable?
V. Ripepi, F. Cusano, M. Di Criscienzo +7
We present the analysis of the time series observations of CoRoT\,102699796 obtained by the CoRoT satellite that show the presence of five independent oscillation frequencies in th…
CORS Baade-Wesselink method in the Walraven photometric system: the Period-Radius and the Period-Luminosity relation of Classical Cepheids
R. Molinaro, V. Ripepi, M. Marconi +4
We present a new derivation of the CORS Baade-Wesselink method in the Walraven photometric system. We solved the complete Baade-Wesselink equation by calibrating the surface bright…
