Abstract
Results. We report the discovery of a warm super-Jovian companion around HD114082 based on a 109.8 +/- 0.4 day signal in the combined RV data from FEROS and HARPS, and on one transit event in the TESS photometry. The best-fit model indicates a 8.0 +/- 1.0M(Jup) companion with a radius of 1.00 +/- 0.03 R-Jup in an orbit with a semi-major axis of 0.51 +/- 0.01 au and an eccentricity of 0.4 +/- 0.04. The companions orbit is in agreement with the known near edge-on debris disk located at similar to 28 au. HD114082 b is possibly the youngest (15 +/- 6 Myr), and one of only three young ( <100 Myr) giant planetary companions for which both their mass and radius have been determined observationally. It is probably the first properly model-constraining giant planet that allows distinguishing between hot and cold-start models. It is significantly more compatible with the cold-start model.
