    Imaging the heart of astrophysical objects with optical long-baseline interferometry

    The number of publications of aperture-synthesis images based on optical long-baseline interferometry measurements has recently increased due to easier access to visible and infrared interferometers. The inter...

    Chemical Analysis of Extragalactic Carbon Stars

    We have performed the chemical analysis of extragalactic carbon stars from VLT/UVES spectra. The derived individual abundances of metals and s-elements as well as the well known distance of the selected stars ...

    Evidence of Mixing in Extremely Metal-Poor Giants

    Thirty five extremely metal-poor (EMP) giants (22 of them with a metallicity [Fe/H] ≤ -3.0) have been observed with UVES at the VLT. In these stars the abundance of lithium carbon and nitrogen and also the 12C/13

    Sulphur in the Early Ages of the Galaxy

    We present here the results of the measurement of the sulphur abundance in very metal-poor stars. Our sample covers the [-4;-2] range of metallicity, and thus allows us to constraint the chemical evolution mod...

    Abundance of Heavy Elements in Extremely Metal-Poor Stars

    In the framework of the VLT Large program “First Stars” (165.N-0276(A)), we have measured the abundance of 13 heavy elements using high quality UVES spectra. In this paper, we report on the abundance of Sr and...
