    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...

    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...
