TESS radial velocities of TOI-4406, -2338 and -2589

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.
