    Spectroscopic parameters for solar-type stars with moderate-to-high rotation. New parameters for ten planet hosts
    Context. Planetary studies demand precise and accurate stellar parameters as input for inferring the planetary properties. Different methods often provide...

    Spectroscopic stellar parameters for 582 FGK stars in the HARPS volume-limited sample. Revising the metallicity-planet correlation
    To understand the formation and evolution of solar-type stars and planets in the solar neighborhood, we need to obtain their stellar parameters with high...

    Spectroscopic study of Ceres' collisional family candidates
    Context. Despite the observed signs of large impacts on the surface of Ceres, there is no confirmed collisional family associated with this dwarf planet. After...

    Spectroscopic variability of two Oe stars
    Context. The two Oe stars HD 45 314 and HD 60 848 have recently been found to exhibit very different X-ray properties: whilst HD 60 848 has an X-ray spectrum...

    Spectroscopic [Fe/H] for 98 extra-solar planet-host stars. Exploring the probability of planet formation
    We present stellar parameters and metallicities, obtained from a detailed spectroscopic analysis, for a large sample of 98 stars known to be orbited by...

    Spectroscopy and multiband photometry of the afterglow of intermediate duration γ-ray burst GRB 040924 and its host galaxy
    Aims: We present optical photometry and spectroscopy of the afterglow and host galaxy of gamma-ray burst GRB 040924. This GRB had a rather short duration of T90...

    Spectroscopy at the solar limb. I. Average off-limb profiles and Doppler shifts of Ca II H
    Aims: We present constraints on the thermodynamical structure of the chromosphere from ground-based observations of the Ca ii H line profile near and off the...

    Spectroscopy of early-type star candidates in M 33 and NGC 6822. II
    We present ground-based spectra of early-type star candidates in the Local Group galaxies M 33 and NGC 6822 taken at the 4.2 m William Herschel Telescope (La...
