    Confidence levels of evolutionary synthesis models. II. On sampling and Poissonian fluctuations
    In terms of statistical fluctuations, stellar population synthesis models are only asymptotically correct in the limit of a large number of stars, where...

    Confirmation of a Sub-Saturn-size Transiting Exoplanet Orbiting a G Dwarf: TOI-1194 b and a Very Low Mass Companion Star: TOI-1251 B from TESS
    We report the confirmation of a sub-Saturn-size exoplanet, TOI-1194 b, with a mass of about ${0.456}_{-0.051}^{+0.055}$ M J, and a very low mass companion star...

    Confirmation of TiO absorption and tentative detection of MgH and CrH in the atmosphere of HAT-P-41b
    Understanding the role of optical absorbers is critical for linking the properties of the dayside and terminator atmospheres of hot Jupiters. This study aims to...

    Connecting photometric and spectroscopic granulation signals with CHEOPS and ESPRESSO
    Context. Stellar granulation generates fluctuations in photometric and spectroscopic data whose properties depend on the stellar type, composition, and...

    Constraining clumpy dusty torus models using optimized filter sets
    Recent success in explaining several properties of the dusty torus around the central engine of active galactic nuclei has been gathered with the assumption of...

    Constraining Lorentz Invariance Violation Using the Crab Pulsar Emission Observed up to TeV Energies by MAGIC
    Spontaneous breaking of Lorentz symmetry at energies on the order of the Planck energy or lower is predicted by many quantum gravity theories, implying non...

    Constraining magnetic-activity modulations in three solar-like stars observed by CoRoT and NARVAL
    Context. Stellar activity cycles are the manifestation of dynamo process running in the stellar interiors. They have been observed from years to decades thanks...
