    Chemical abundances of planet-host stars. Results for alpha and Fe-group elements
    In this paper, we present a study of the abundances of Si, Ca, Sc, Ti, V, Cr, Mn, Co, and Ni in a large set of stars known to harbor giant planets, as well as...

    Fine structure in the local interstellar medium.
    The authors examine, using K I and Na I absorptions, a generally conical volume out to some 200 pc from the Sun placing constraints on a number of the...

    Fluorine in the Solar Neighborhood: No Evidence for the Neutrino Process
    Asymptotic giant branch (AGB) stars are known to produce “cosmic” fluorine, but it is uncertain whether these stars are the main producers of fluorine in the...

    Gaia Early Data Release 3. The Gaia Catalogue of Nearby Stars
    Aims: We produce a clean and well-characterised catalogue of objects within 100 pc of the Sun from the Gaia Early Data Release 3. We characterise the catalogue...

    Habitable Planets Eclipsing Brown Dwarfs: Strategies for Detection and Characterization
    Given the very close proximity of their habitable zones, brown dwarfs (BDs) represent high-value targets in the search for nearby transiting habitable planets...

    Inflow of Gas to the Solar Neighborhood during Evolution of the Galactic Disk
    We discuss several lines of evidence indicating that gas is flowing into the solar neighborhood and go on to offer a theoretical framework to explain this...
