•RV: thanks to 1 m/s precision observations, a new huge population of low mass <strong>planets</strong><br />
has emerged in the last few years (mostly <strong>planets</strong> found by HARPS).<br />
•bi (tri?) modal distribution: minimum at about 30 Earth masses. Imprint of formation?<br />
•neptunian bump: strong increase between 30-15 ME.<br />
•overall maximum at small masses<br />
•more than 50% of solar-type stars harbor at least one planet of any mass and with<br />
period up to 100 days (!)
