Planets around young stars trace the early evolution of planetary systems. We report the discovery and validation of two planetary systems with ages lesssim300 Myr from observations by the Transiting Exoplanet Survey Satellite (TESS). The $40\mbox{--}320$Myr old G star TOI-251 hosts a ${2.74}_{-0.18}^{+0.18}\,{R}_{\oplus }$mini-Neptune with a $4.94$day period. The $20\mbox{--}160$Myr old K star TOI-942 hosts a system of inflated Neptune-sized planets, with TOI-942b orbiting in a period of $4.32$days with a radius of ${4.81}_{-0.20}^{+0.20}\,{R}_{\oplus }$and TOI-942c orbiting in a period of $10.16$days with a radius of ${5.79}_{-0.18}^{+0.19}\,{R}_{\oplus }$. Though we cannot place either host star into a known stellar association …

The interiors of giant planets remain poorly understood. Even for the planets in the Solar System, difficulties in observation lead to large uncertainties in the properties of planetary cores. Exoplanets that have undergone rare evolutionary processes provide a route to understanding planetary interiors. Planets found in and near the typically barren hot-Neptune ‘desert’1,2 (a region in mass–radius space that contains few planets) have proved to be particularly valuable in this regard. These planets include HD149026b3, which is thought to have an unusually massive core, and recent discoveries such as LTT9779b4 and NGTS-4b5, on which photoevaporation has removed a substantial part …
