    Low-amplitude rotational modulation rather than pulsations in the CoRoT B-type supergiant HD 46769
    Aims: We aim to detect and interpret photometric and spectroscopic variability of the bright CoRoT B-type supergiant target HD 46769 (V = 5.79). We also attempt...

    Low-frequency gravity waves in blue supergiants revealed by high-precision space photometry
    Almost all massive stars explode as supernovae and form a black hole or neutron star. The remnant mass and the impact of the chemical yield on subsequent star...

    Low-frequency photospheric and wind variability in the early-B supergiant HD 2905
    Context. Despite important advances in space asteroseismology during the last decade, the early phases of evolution of stars with masses above 15 M⊙ (including...

    Low-mass low-metallicity AGB stars as an efficient i-process site explaining CEMP-rs stars
    Context. Among carbon-enhanced metal-poor (CEMP) stars, some are found to be enriched in slow-neutron capture (s-process) elements (and are then tagged CEMP-s)...

    Low-resolution spectroscopy of main sequence stars belonging to 12 Galactic globular clusters. I. CH and CN band strength variations
    Context. Globular clusters show star-to-star abundance variations for light elements that are not yet well understood. The preferred explanation involves a self...

    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...

    Lucky Spectroscopy, an equivalent technique to Lucky Imaging. Spatially resolved spectroscopy of massive close visual binaries using the William Herschel Telescope
    Context. Many massive stars have nearby companions whose presence hamper their characterization through spectroscopy. Aims: We want to obtain spatially resolved...

    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...

    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...
