    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...

    TOI-4860 b, a short-period giant planet transiting an M3.5 dwarf
    We report the discovery and characterisation of a giant transiting planet orbiting a nearby M3.5V dwarf (d = 80.4pc, G = 15.1 mag, K=11.2mag, R * = 0.358 ± 0...

    TOI-5005 b: A super-Neptune in the savanna near the ridge
    Context. The Neptunian desert and savanna have recently been found to be separated by a ridge, an overdensity of planets in the period range of ≃3–5 days. These...

    TOI-519 b: A short-period substellar object around an M dwarf validated using multicolour photometry and phase curve analysis
    Context. We report the discovery of TOI-519 b (TIC 218795833), a transiting substellar object (R = 1.07 R Jup) orbiting a faint M dwarf (V = 17.35) on a 1.26 d...

    TOI-5678b: A 48-day transiting Neptune-mass planet characterized with CHEOPS and HARPS★
    Context. A large sample of long-period giant planets has been discovered thanks to long-term radial velocity surveys, but only a few dozen of these planets have...

    TOI-663: A newly discovered multi-planet system with three transiting mini-Neptunes orbiting an early M star
    We present the detection of three exoplanets orbiting the early M dwarf TOI-663 (TIC 54962195; V = 13.7 mag, J = 10.4 mag, R ★ = 0.512 ± 0.015 R ⊙, M ★ = 0.514...
