cds-question@unistra.frexoplanetsf-starsinfrared-photometryvisible-astronomyspectroscopyradial-velocityWe report the discovery and orbital characterization of three new transiting warm giant planets. These systems were initially identified as presenting single-transit events in the light curves generated from the full-frame images of the Transiting Exoplanet Survey Satellite. Follow-up radial velocity measurements and additional light curves were used to determine the orbital periods and confirm the planetary nature of the candidates. The planets orbit slightly metal-rich late F- and early G-type stars. We find that TOI4406b has a mass of MP=0.30{+/-}0.04MJup, a radius of RP=1.00{+/-}0.02RJup, and a low-eccentricity orbit (e=0.15{+/-}0.05) with a period of P=30.08364{+/-}0.00005days. TOI2338b has a mass of M =5.98{+/-}0.20MJup, a radius of RP=1.00{+/-}0.01RJup, and a highly eccentric orbit (e=0.676{+/-}0.002) with a period of P=22.65398{+/-}0.00002days. Finally, TOI2589b has a mass of MP=3.50{+/-}0.10MJup, a radius of RP=1.08{+/-}0.03RJup, and an eccentric orbit (e=0.522{+/-}0.006) with a period of P=61.6277{+/-}0.0002days. TOI4406b and TOI2338b are enriched in metals compared to their host stars, while the structure of TOI2589b is consistent with having similar metal enrichment to its host star.2023AJ....165..227Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/165/227CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/ApJ/757/18 : Radial velocities 16 hot Jupiter host stars (Albrecht+, 2012)J/A+A/546/A14 : Limb-darkening for CoRoT, Kepler, Spitzer (Claret+, 2012)J/A+A/552/A16 : Limb-darkening for CoRoT, Kepler, Spitzer.
