    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 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 activities and kinematics for solar type dwarfs and subgiants: analysis of the activity distribution and the AVR
    Aims: In this work we present chromospheric activity indices, kinematics, radial-velocities, and rotational velocities for more than 850 FGK-type dwarfs and...
