    Titanium chemistry of WASP-121 b with ESPRESSO in 4-UT mode
    Transit spectroscopy usually relies on the integration of one or several transits to achieve the signal-to-noise ratio (S/N) necessary to resolve spectral...

    TMCalc - a fast code to derive Teff and [Fe/H] for FGK stars
    We present a new direct spectroscopic calibration for a fast estimation of the stellar metallicity [Fe/H]. This calibration was computed using a large sample of...

    To clump or not to clump. The impact of wind inhomogeneities on the optical and NIR spectroscopic analysis of massive OB stars
    Context. Winds of massive stars have density inhomogeneities (clumping) that may affect the formation of spectral lines in different ways, depending on their...

    TOI-1055 b: Neptunian planet characterised with HARPS, TESS, and CHEOPS
    Context. TOI-1055 is a Sun-like star known to host a transiting Neptune-sized planet on a 17.5-day orbit (TOI-1055 b). Radial velocity (RV) analyses carried out...

    TOI-1130: A photodynamical analysis of a hot Jupiter in resonance with an inner low-mass planet
    The TOI-1130 is a known planetary system around a K-dwarf consisting of a gas giant planet, TOI-1130 c on an 8.4-day orbit that is accompanied by an inner...

    TOI-1135 b: A young hot Saturn-size planet orbiting a solar-type star
    Despite the thousands of planets in orbit around stars known to date, the mechanisms of planetary formation, migration, and atmospheric loss remain unresolved...

    TOI-1199 b and TOI-1273 b: Two new transiting hot Saturns detected and characterized with SOPHIE and TESS
    We report the characterization of two planet candidates detected by the Transiting Exoplanet Survey Satellite (TESS), TOI-1199 b and TOI-1273 b, with periods of...

    TOI-1201 b: A mini-Neptune transiting a bright and moderately young M dwarf
    We present the discovery of a transiting mini-Neptune around TOI-1201, a relatively bright and moderately young early M dwarf (J ≈ 9.5 mag, ~600-800 Myr) in an...

    TOI-1268b: The youngest hot Saturn-mass transiting exoplanet
    We report the discovery of TOI-1268b, a transiting Saturn-mass planet from the TESS space mission. With an age of less than 1 Gyr, derived from various age...
