    beta Centauri: An eccentric binary with two beta Cep-type components
    We introduce our observational study of the orbital motion and the intrinsic variability of the double-lined spectroscopic binary beta Cen. Using 463 high...

    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...

    Bimodal dust emission in three classical Seyfert galaxies: NGC 3227, NGC 4051 and NGC 4151.
    Far Infrared observations of the Seyfert galaxies NGC 3227, NGC 4051 and NGC 4151 are presented. These are the first data from a complete sample of Seyfert...

    Binarity at LOw Metallicity (BLOeM): A spectroscopic VLT monitoring survey of massive stars in the SMC
    Surveys in the Milky Way and Large Magellanic Cloud have revealed that the majority of massive stars will interact with companions during their lives. However...

    Binarity at the L/T brown dwarf transition. Adaptive optics search for companions
    Context: Current atmospheric models cannot reproduce some of the characteristics of the transition between the L dwarfs with cloudy atmospheres and the T dwarfs...

    Binary frequency of planet-host stars at wide separations. A new brown dwarf companion to a planet-host star
    Aims: The aim of the project is to improve our knowledge on the multiplicity of planet-host stars at wide physical separations. Methods: We cross-matched...

    Binary star population of the Sculptor dwarf galaxy
    Aims: We aim to compute the binary fraction of "classical" dwarf spheroidal galaxies (dSphs) that are satellites of the Milky Way (MW). This value can offer...

    Black hole feeding and star formation in NGC 1808
    We report on Atacama Large Millimeter Array (ALMA) observations of CO(3−2) emission in the Seyfert2/starburst galaxy NGC 1808, at a spatial resolution of 4 pc...
