A statistical study on young giant planets from radial velocity surveys 


The study of the close to 5000 exoplanets and brown dwarfs companions known to date has evidenced the importance of early evolution stages of planet formation processes. Yet, a better understanding of these processes can be obtained by constraining the occurrence rates of these objects at young ages. In this seminar will be presented the results of 3 large radial velocity surveys that were dedicated to the search for short period (P<1000 days) young giant planets with the aim to deduce their occurrence rate.
