    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...

    Abundance trend with condensation temperature for stars with different Galactic birth places
    Context. During the past decade, several studies reported a correlation between chemical abundances of stars and condensation temperature (also known as Tc...

    Abundances of disk and bulge giants from high-resolution optical spectra. I. O, Mg, Ca, and Ti in the solar neighborhood and Kepler field samples
    Context. The Galactic bulge is an intriguing and significant part of our Galaxy, but it is hard to observe because it is both distant and covered by dust in the...
