    Absence of nuclear polycyclic aromatic hydrocarbon emission from a compact starburst: The case of the type-2 quasar Mrk 477
    Mrk 477 is the closest type-2 quasar, at a distance of 163 Mpc. This makes it an ideal laboratory for studying the interplay between nuclear activity and star...

    Absence of radio-bright dominance in a near-infrared selected sample of red quasars
    Context. The dichotomy between red and blue quasars is still an open question. It is debated whether red quasars are simply blue quasars that are observed at...

    Absence of significant cross-correlation between WMAP and SDSS
    Aims: Several authors have claimed to detect a significant cross-correlation between microwave WMAP anisotropies and the SDSS galaxy distribution. We repeat...

    Absolute dimensions and apsidal motion of the eclipsing binaries V889 Aquilae and V402 Lacertae
    Context. Double-lined eclipsing binaries allow the direct determination of masses and radii, which are key for testing stellar models. With the launch of the...

    Absolute dimensions of the low-mass eclipsing binary system NSVS 10653195
    Context. Low-mass stars in eclipsing binary systems show radii larger and effective temperatures lower than theoretical stellar models predict for isolated...

    Absolute motions of globular clusters. II. HST astrometry and VLT radial velocities in NGC 6397
    In this paper we present a new, accurate determination of the three components of the absolute space velocity of the Galactic globular cluster NGC 6397 (l≃338°...

    Abundance anomalies in hot horizontal branch stars of the galactic globular cluster NGC1904
    We present abundance measurements, based on high-resolution optical spectroscopic data obtained with the Ultraviolet and Visual Echelle Spectrograph mounted on...

    Abundance ratios of volatile vs. refractory elements in planet-harbouring stars: hints of pollution?
    We present the [ X/H] trends as a function of the elemental condensation temperature TC in 88 planet host stars and in a volume-limited comparison sample of 33...

    Abundance to age ratios in the HARPS-GTO sample with Gaia DR2. Chemical clocks for a range of [Fe/H]
    Aims: The purpose of this work is to evaluate how several elements produced by different nucleosynthesis processes behave with stellar age and provide empirical...
