Abstract

Detecting planets around young stars, and in particular measuring their masses, is a key step to test models of planet formation and evolution, and migration mechanisms. Nowadays, with the TESS photometric observations providing interesting transiting candidates, members of young (e.g., Taurus, Cepheus) and intermediate age (e.g. Coma Ber, Hyades) associations are becoming popular targets for radial velocity (RV) follow-up campaigns. Among others, they are monitored by the Italian GAPS (Global Architecture of Planetary Systems) long-term project, which takes advantage of the HARPS -N and GIANO spectrographs mounted at the TNG . In my talk I will give a brief overview of recent results which are contributing to populating the mass-radius diagram of young planets. In particular, I will discuss some promising systems monitored by GAPS , presenting results and underlining critical points which have emerged during a four-years long experience.
