    Benchmark stars, benchmark spectrographs. Detailed spectroscopic comparison of ESPRESSO, PEPSI, and HARPS data for Gaia benchmark stars
    Context. Gaia benchmark stars are selected to be calibration stars for different spectroscopic surveys. Very high-quality and homogeneous spectroscopic data for...
  • Publication
    Benchmark tests of transmission spectroscopy using transiting white dwarfs
    Context. Ground-based transit observations are affected by both telluric absorption and instrumental systematics, which can affect the final retrieved...

    Beryllium abundances in late-type Hyades dwarf stars.
    We have observed, with high spectral resolution, the BeII resonance doublet at λ 3131A in five G and K-type main-sequence stars belonging to the Hyades open...

    Beryllium abundances in parent stars of extrasolar planets: 16 Cygni A & B and rho (1) CANCRI
    The (9) Be ii lambda 3131 Angstroms doublet has been observed in the solar-type stars 16 Cyg A & B and in the late G-type star rho (1) Cnc, to derive their...

    Beryllium abundances in stars hosting giant planets
    We have derived beryllium abundances in a wide sample of stars hosting planets, with spectral types in the range F7V-K0V, aimed at studying in detail the...

    Beryllium abundances in stars with planets. Extending the sample
    Context. Chemical abundances of light elements such as beryllium in planet-host stars allow us to study the planet formation scenarios and/or investigate...

    Beryllium anomalies in solar-type field stars
    We present a study of beryllium (Be) abundances in a large sample of field solar-type dwarfs and sub-giants spanning a large range of effective temperatures...
