    TOI-2257 b: A highly eccentric long-period sub-Neptune transiting a nearby M dwarf
    Context. Thanks to the relative ease of finding and characterizing small planets around M-dwarf stars, these objects have become cornerstones in the field of...

    TOI-2266 b: A keystone super-Earth at the edge of the M dwarf radius valley
    We validate the Transiting Exoplanet Survey Satellite (TESS) object of interest TOI-2266.01 (TIC 8348911) as a small transiting planet (most likely a super...

    TOI-2285b: A 1.7 Earth-radius planet near the habitable zone around a nearby M dwarf
    We report the discovery of TOI-2285b, a sub-Neptune-sized planet transiting a nearby (42 pc) M dwarf with a period of 27.3 d. We identified the transit signal...

    TOI-257b (HD 19916b): a warm sub-saturn orbiting an evolved F-type star
    We report the discovery of a warm sub-Saturn, TOI-257b (HD 19916b), based on data from NASA's Transiting Exoplanet Survey Satellite (TESS). The transit signal...

    TOI-269 b: an eccentric sub-Neptune transiting a M2 dwarf revisited with ExTrA
    We present the confirmation of a new sub-Neptune close to the transition between super-Earths and sub-Neptunes transiting the M2 dwarf TOI-269 (TIC 220 479 565...

    TOI-3884 b: A rare 6-R<SUB>E</SUB> planet that transits a low-mass star with a giant and likely polar spot
    The Transiting Exoplanet Survey Satellite mission identified a deep and asymmetric transit-like signal with a periodicity of 4.5 days orbiting the M4 dwarf star...

    TOI-4336 A b: A temperate sub-Neptune ripe for atmospheric characterization in a nearby triple M-dwarf system
    Context. Small planets transiting bright nearby stars are essential to our understanding of the formation and evolution of exoplanetary systems. However, few...

    TOI-4438 b: a transiting mini-Neptune amenable to atmospheric characterization
    We report the confirmation and mass determination of a mini-Neptune transiting the M3.5 V star TOI-4438 (G 182-34) every 7.44 days. A transit signal was...
