We present the discovery and characterization of three transiting planets orbiting the F8V star HD 28109 (= TOI-282). The two outer planets were identified by TESS and followed up by our team; these planets are fluffy Neptunes with orbital periods of 56 and 84.3 days, a period ratio very close to that of the first-order 3:2 mean motion resonance. A third, inner planet with an orbital period of 22.9 days was discovered in the TESS photometry and radial velocity follow-up. This planet is at the border of the super-Earth / sub-Neptune regime with a density of Earth. The results are currently published in Dransfield et al. (MNRAS).
