    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...

    TOI-1416: A system with a super-Earth planet with a 1.07 d period
    TOI-1416 (BD+42 2504, HIP 70705) is a V =10 late G- or early K-type dwarf star. TESS detected transits in its Sectors 16, 23, and 50 with a depth of about 455...

    TOI-1442 b and TOI-2445 b: Two potentially rocky ultra-short period planets around M dwarfs
    Context. Exoplanets with orbital periods of less than one day are known as ultra-short period (USP) planets. They are relatively rare products of planetary...

    TOI-1468: A system of two transiting planets, a super-Earth and a mini-Neptune, on opposite sides of the radius valley
    We report the discovery and characterization of two small transiting planets orbiting the bright M3.0V star TOI-1468 (LSPM J0106+1913), whose transit signals...

    TOI-1801 b: A temperate mini-Neptune around a young M0.5 dwarf
    We report the discovery, mass, and radius determination of TOI-1801 b, a temperate mini-Neptune around a young M dwarf. TOI-1801 b was observed in TESS sectors...

    TOI-2084 b and TOI-4184 b: Two new sub-Neptunes around M dwarf stars
    We present the discovery and validation of two TESS exoplanets orbiting nearby M dwarfs: TOI-2084 b, and TOI-4184b. We characterized the host stars by combining...

    TOI-2196 b: Rare planet in the hot Neptune desert transiting a G-type star
    The hot Neptune desert is a region hosting a small number of short-period Neptunes in the radius-instellation diagram. Highly irradiated planets are usually...

    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...
