    Chemical composition of Galactic OB stars. II. The fast rotator ζ Ophiuchi
    ζ Oph, HD 149757, is an O9.5 Vnn star with a very high projected rotational velocity (v sin i ≥ 340 km s-1). It is also a classical runaway star due to its high...

    Chemical composition of the young massive cluster NGC 1569-B
    Context. The chemical composition of young massive clusters (YMCs) provides stellar population information on their host galaxy. As potential precursors of...

    Chemical distribution of H II regions towards the Galactic anticentre
    Context. The study of the radial variations of metallicity across the Galactic disc is a powerful method for understanding the history of star formation and...

    Chemical evolution of elliptical galaxies with a variable IMF. A publicly available code
    Growing evidence in recent years suggests a systematic variation of the stellar initial mass function (IMF), being top-heavy for starburst galaxies and possibly...

    Chemical evolution of ultra-faint dwarf galaxies in the self-consistently calculated integrated galactic IMF theory
    The galaxy-wide stellar initial mass function (gwIMF) of a galaxy in dependence on its metallicity and star formation rate can be calculated by the integrated...

    Chemical tagging of the Ursa Major moving group. A northern selection of FGK stars
    Context. Stellar kinematic groups are kinematically coherent groups of stars that might have a common origin. These groups spread through the Galaxy over time...
  • Publication
    Chemically tagging the Hyades Supercluster. A homogeneous sample of F6-K4 kinematically selected northern stars
    Stellar kinematic groups are kinematical coherent groups of stars that might have a common origin. These groups are dispersed throughout the Galaxy over time by...

    Chemodynamics of the Milky Way. I. The first year of APOGEE data
    Context. The Apache Point Observatory Galactic Evolution Experiment (APOGEE) features the first multi-object high-resolution fiber spectrograph in the near...

    CHEOPS and TESS view of the ultra-short-period super-Earth TOI-561 b
    Context. Ultra-short-period planets (USPs) are a unique class of super-Earths with an orbital period of less than a day, and hence they are subject to intense...
