    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 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...

    Chromospheric polarimetry through multiline observations of the 850 nm spectral region III: Chromospheric jets driven by twisted magnetic fields
    We investigate the diagnostic potential of the spectral lines at 850 nm for understanding the magnetism of the lower atmosphere. For that purpose, we use a...

    Chromospheric polarimetry through multiline observations of the 850-nm spectral region - II. A magnetic flux tube scenario
    In this publication, we continue the work started in Quintero Noda et al., examining this time a numerical simulation of a magnetic flux tube concentration. Our...

    Chromospheric reversals in the emergence of an ephemeral region
    Context: The behaviour of both ephemeral regions and moving magnetic features has been often described for the photospheric layer, but not for the chromosphere...
