    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...

    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...
