    Linking the primordial composition of planet building disks to the present-day composition of rocky exoplanets
    Context. The composition of rocky planets is strongly driven by the primordial materials in the protoplanetary disk, which can be inferred from the abundances...
  • Publication
    Links between the dynamical evolution and the surface color of the Centaurs
    Context. The Centaurs are a transitional population of minor bodies of the solar system and the evolutionary link between the trans-Neptunian objects and the...
  • Publication
    Lithium abundance and rotation of seismic solar analogues. Solar and stellar connection from Kepler and Hermes observations
    Context. Lithium abundance A(Li) and surface rotation are good diagnostic tools to probe the internal mixing and angular momentum transfer in stars. Aims: We...
  • Publication
    Lithium Abundances in a Flux-Limited Sample of Galactic Carbon Stars
    Lithium abundances, or upper limits, have been derived for 161 galactic carbon stars, selected from the Two Micron Sky Survey, using high resolution, high...
  • Publication
    Lithium and Hα in stars and brown dwarfs of sigma Orionis.
    We present intermediate- and low-resolution optical spectra around Hα and Li I lambda 6708 Åfor a sample of 25 low mass stars and 2 brown dwarfs with confirmed...

    Lithium and zirconium abundances in massive Galactic O-rich AGB stars
    Lithium and zirconium abundances (the latter taken as representative of s-process enrichment) are determined for a large sample of massive Galactic O-rich AGB...
  • Publication
    Lithium depletion boundary, stellar associations, and Gaia
    Context. Stellar ages are key to improving our understanding of different astrophysical phenomena. However, many techniques to estimate stellar ages are highly...
  • Publication
    Lithium in ROSAT-discovered candidate members in the Alpha Persei cluster
    We present lithium observations of 23 X-ray selected candidate members of alpha Per, which are part of a larger sample of stars identified through two ROSAT...
  • Publication
    Lithium in stars with exoplanets
    We present a comparison of the lithium abundances of stars with and without planetary-mass companions. New lithium abundances are reported in 79 planet hosts...
