    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...

    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...

    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...

    CHEOPS finds KELT-1b darker than expected in visible light. Discrepancy between the CHEOPS and TESS eclipse depths
    Recent studies based on photometry from the Transiting Exoplanet Survey Satellite (TESS) have suggested that the dayside of KELT-1b, a strongly irradiated brown...

    CHEOPS geometric albedo of the hot Jupiter HD 209458 b
    We report the detection of the secondary eclipse of the hot Jupiter HD 209458 b in optical/visible light using the CHEOPS space telescope. Our measurement of 20...

    CHEOPS in-flight performance. A comprehensive look at the first 3.5 yr of operations
    Context. Since the discovery of the first exoplanet almost three decades ago, the number of known exoplanets has increased dramatically. By beginning of the...

    CHEOPS observations of KELT-20 b/MASCARA-2 b: An aligned orbit and signs of variability from a reflective day side
    Context. Occultations are windows of opportunity to indirectly peek into the dayside atmosphere of exoplanets. High-precision transit events provide information...

    CHEOPS observations of the HD 108236 planetary system: a fifth planet, improved ephemerides, and planetary radii
    Context. The detection of a super-Earth and three mini-Neptunes transiting the bright (V = 9.2 mag) star HD 108236 (also known as TOI-1233) was recently...
