    BS Indi: An enigmatic object in the Tucana association
    BS Ind (=HD 202947) is a young K0V star in the Tucana association. Photometric observations with the Hipparcos satellite show an eclipse-like light-curve with...

    Building the cosmic infrared background brick by brick with Herschel/PEP
    The cosmic infrared background (CIB) includes roughly half of the energy radiated by all galaxies at all wavelengths across cosmic time, as observed at the...

    Bulges of disk galaxies at intermediate redshifts. I. Samples with and without bulges in the Groth Strip survey
    Context: Analysis of bulges to redshifts of up to z ˜ 1 have provided ambiguous results as to whether bulges as a class are old structures akin to elliptical...

    Bulges of disk galaxies at intermediate redshifts. II. Nuclear, disk, and global colors in the Groth Strip
    Context: The chronology of bulge and disk formation is a major unsolved issue in galaxy formation, which impacts on our global understanding of the Hubble...

    Burst-properties as a function of mass accretion rate in GX 3+1
    GX 3+1 is a low-mass X-ray binary that is persistently bright since its discovery in 1964. It was found to be an X-ray burster twenty years ago proving that the...

    Bursts, eclipses, dips and a refined position for the luminous low-mass X-ray binary in the globular cluster Terzan 6
    GRS 1747-312 is a bright transient X-ray source in the globular cluster Terzan 6 with quasi-periodic outbursts approximately every 4.5 months. We carried out 2...

    C and N abundances of main sequence and subgiant branch stars in NGC 1851
    We present the first chemical analysis of stars on the double subgiant branch (SGB) of the globular cluster NGC 1851. We obtained 48 Magellan IMACS spectra of...

    C, S, Zn and Cu abundances in planet-harbouring stars
    We present a detailed and uniform study of C, S, Zn and Cu abundances in a large set of planet host stars, as well as in a homogeneous comparison sample of...

    C/O vs. Mg/Si ratios in solar type stars: The HARPS sample
    Context. Aims: We aim to present a detailed study of the magnesium-to-silicon and carbon-to-oxygen ratios (Mg/Si and C/O) and their importance in determining...
