PublicationTOI-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...

PublicationTOI-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...

PublicationTOI-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...

PublicationTOI-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...

PublicationTOI-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...

PublicationTOI-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...

PublicationTOI-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...

PublicationTOI-674b: An oasis in the desert of exo-Neptunes transiting a nearby M dwarf
Context. The NASA mission TESS is currently doing an all-sky survey from space to detect transiting planets around bright stars. As part of the validation...
