    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 an exoplanet using the transit color signature: Kepler-418b, a blended giant planet in a multiplanet system
    Aims: We announce confirmation of Kepler-418b, one of two proposed planets in this system. This is the first confirmation of an exoplanet based primarily on the...

    Confirmation of an He I evaporating atmosphere around the 650-Myr-old sub-Neptune HD 235088 b (TOI-1430 b) with CARMENES
    HD 235088 (TOI-1430) is a young star known to host a sub-Neptune-sized planet candidate. We validated the planetary nature of HD 235088 b with multiband...

    Confirmation of the planet hypothesis for the long-period radial velocity variations of β Geminorum
    Aims.Our aim is to confirm the nature of the long period radial velocity measurements for β Gem first found by Hatzes & Cochran (1993). Methods: .We present...

    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...
