    The Carina Project. I. Bright Variable Stars
    We present new BV time series data of the Carina dwarf spheroidal galaxy (dSph). Current data cover an area of ~0.3 deg2 around the center of the galaxy and...
  • Publication
    The Carina Project. II. Stellar Populations
    We present a new (V, B-V) color-magnitude diagram of the Carina dwarf spheroidal galaxy (dSph) that extends from the tip of the red giant branch (RGB) down to V...
  • Publication
    The Carina Project. VI. The Helium-burning Variable Stars
    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...

    The Carina Project. VII. Toward the Breaking of the Age-Metallicity Degeneracy of Red Giant Branch Stars Using the C U, B, I Index
    We present an analysis of photometric and spectroscopic data of the Carina dSph galaxy, testing a new approach similar to that used to disentangle multiple...
  • Publication
    The Carina Project. VIII. The α-element abundances
    We have performed a new abundance analysis of Carina red giant (RG) stars from spectroscopic data collected with UVES (high spectral resolution) and FLAMES...
  • Publication
    The Carina Project. X. On the Kinematics of Old and Intermediate-age Stellar Populations1,2
    We present new radial velocity (RV) measurements of old (horizontal branch) and intermediate-age (red clump) stellar tracers in the Carina dwarf spheroidal...

    The Carina Project: Absolute and Relative Calibrations
    We discuss the reduction strategy adopted to perform the relative and the absolute calibration of the Wide Field Imager (WFI) available at the 2.2m ESO/MPI...
  • Publication
    The Carina Project: bright variables
    We present recent results on variable stars in the Carina Dwarf Galaxy based on B,V time series data collected over three consecutive nights with the Wide Field...
  • Publication
    The Carina Project: color magnitude diagram and radial distribution
    We present B, V photometric data of the Carina Dwarf Spheroidal Galaxy (dSph), collected with the Wide Field Imager (WFI) available at the 2.2m MPI/ESO...
