    Lucky Imaging Adaptive Optics of the brown dwarf binary GJ569Bab
    The potential of combining Adaptive Optics (AO) and Lucky Imaging (LI) to achieve high-precision astrometry and differential photometry in the optical is...
  • Publication
    Lucky Imaging of M subdwarfs
    Context: The knowledge of the binary properties of metal-poor and solar-metallicity stars can shed light on the potential differences between the formation...
  • Publication
    Lucky imaging speckle statistics applied to halo suppression
    In ground based astronomy, the Lucky Imaging (LI) technique consists of selecting the best quality pictures among those that have been taken with a short...

    Lucky spectroscopy, an equivalent technique to lucky imaging. II. Spatially resolved intermediate-resolution blue-violet spectroscopy of 19 close massive binaries using the William Herschel Telescope
    Context. Many massive stars have nearby companions. These hamper a characterization of massive stars through spectroscopy. Aims: We continue to obtain spatially...

    Luminosity and mass functions of the three main sequences of the globular cluster NGC 2808
    High-precision HST photometry has revealed that the globular cluster (GC) NGC 2808 hosts a triple main sequence (MS) corresponding to three stellar populations...
  • Publication
    Luminosity functions for galaxies and quasars in the Spitzer Wide-area Infrared Extragalactic Legacy Survey
    We construct rest-frame luminosity functions (LFs) at 3.6, 4.5, 5.8, 8 and 24 μm over the redshift range 0 z 2 for galaxies and 0 z 4 for optical quasi...

    Luminosity-colour relations for red clump stars
    We calibrated the absolute magnitudes M V , M J , M_{Ks} and M g of red clump stars in terms of colours. M V and M g are strongly dependent on colour, while the...

    Luminosity-colour relations for thin-disc main-sequence stars
    In this study we present the absolute magnitude calibrations of thin-disc main-sequence stars in the optical , and in the near-infrared . Thin-disc stars are...
