    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...

    Beyond the Nyquist frequency: Asteroseismic catalog of undersampled Kepler late subgiants and early red giants
    Subgiants and early red giants are crucial for studying the first dredge-up, a key evolutionary phase in which the convective envelope deepens, mixing...

    Beyond traditional diagnostics: Identifying active galactic nuclei using spectral energy distribution fitting in DESI data
    Aims. Active galactic nuclei (AGN) are typically identified through their distinctive X-ray or radio emissions, mid-infrared (MIR) colors, or emission lines...

    Biases in galaxy cluster velocity dispersion and mass estimates in the small N<SUB>gal</SUB> regime
    Aims: We present a study of the statistical properties of three velocity dispersion and mass estimators: biweight, gapper, and standard deviation for a small...

    Bidimensional spectroscopy of NGC 4214: evolutionary state and interstellar extinction
    We have mapped spectrophotometrically the star--forming regions in the center of the nearby SBm galaxy NGC 4214 with the aim of analyzing the spatial...
