    B fields in OB stars (BOB): Concluding the FORS 2 observing campaign
    Aims: The B fields in OB stars (BOB) Collaboration is based on an ESO Large Programme to study the occurrence rate, properties, and ultimately the origin of...

    B fields in OB stars (BOB): Low-resolution FORS2 spectropolarimetry of the first sample of 50 massive stars
    Within the context of the collaboration "B fields in OB stars" (BOB), we used the FORS2 low-resolution spectropolarimeter to search for a magnetic field in 50...
  • Publication
    B fields in OB stars (BOB): on the detection of weak magnetic fields in the two early B-type stars β CMa and ɛ CMa. Possible lack of a "magnetic desert" in massive stars
    Only a small fraction of massive stars seem to host a measurable structured magnetic field, whose origin is still unknown and whose implications for stellar...

    B polarization of the CMB from Faraday rotation
    We study the effect of Faraday rotation due to a uniform magnetic field on the polarization of the cosmic microwave background. Scalar fluctuations give rise...

    B-type supergiants in the Small Magellanic Cloud: rotational velocities and implications for evolutionary models
    High-resolution spectra for 24 SMC and Galactic B-type supergiants have been analysed to estimate the contributions of both macroturbulence and rotation to the...
  • Publication
    B-type supergiants in the SMC: Chemical compositions and comparison of static and unified models
    High-resolution UCLES/AAT spectra are presented for nine B-type supergiants in the SMC, chosen on the basis that they may show varying amounts of nuclear...

    B1359+154: A Six-Image Lens Produced by a z ~= 1 Compact Group of Galaxies
    Hubble Space Telescope (HST) V- and I-band observations show that the gravitational lens B1359+154 consists of six images of a single zs=3.235 radio source and...

    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...

    BACCHUS Analysis of Weak Lines in APOGEE Spectra (BAWLAS)
    Elements with weak and blended spectral features in stellar spectra are challenging to measure and require specialized analysis methods to precisely measure...
