    Baade's window and APOGEE. Metallicities, ages, and chemical abundances
    Context. Baade's window (BW) is one of the most observed Galactic bulge fields in terms of chemical abundances. Owing to its low and homogeneous interstellar...

    Balloon 090100001: A bright, high amplitude sdB pulsator
    We report the discovery of pulsations in the light curve of Balloon 090100001, a bright sdB star (B=11.8) from the balloon-borne survey of Bixler et al. (1991)...

    Balloon 090100001: A short and long period pulsating sdB star
    We report the discovery of long period oscillations in the light curve of the bright sdB pulsator Balloon 090100001. We find at least three peaks in the low...

    Balmer lines emission region in NGC 3516: Kinematical and physical properties
    We have studied the Balmer line shapes of NGC 3516 in order to find the structure of central Emission Line Region (ELR) and the physical parameters of the...

    Bar pattern speed evolution over the last 7 Gyr
    Context. The tumbling pattern of a bar is the main parameter characterising its dynamics. From numerical simulations, its evolution since bar formation is...

    Bar pattern speeds in CALIFA galaxies. I. Fast bars across the Hubble sequence
    Context. The bar pattern speed (Ωb) is defined as the rotational frequency of the bar, and it determines the bar dynamics. Several methods have been proposed...

    Bar pattern speeds in CALIFA galaxies. II. The case of weakly barred galaxies
    Context. About 35% of the nearby disc galaxies host a weak bar for which different formation scenarios, including the weakening of a strong bar and tidal...
  • Publication
    Bar pattern speeds in CALIFA galaxies. III. Solving the puzzle of ultrafast bars
    Context. More than 10% of barred galaxies with a direct measurement of the bar pattern speed host an ultrafast bar. These bars extend well beyond the corotation...

    Bar-driven injection of intergalactic matter into galactic halos
    Aims:The non-conservative gravitational potential of barred galaxies, or of any other non-axisymmetric structure, produces a loss of energy in infalling...
