Studying Planet Formation with a Sample of 5000

Abstract
A large number of transiting super-Earths have now been discovered. But how they are formed, and how they relate to known extra-solar planets and to planets in our own Solar System, remain unsolved. In this talk, I will discuss some recent progress regarding their masses, their composition, and their family portrait, leading to the conclusion that super-Earths are composed of a single population that is surprisingly uniform in their bulk properties. This and other results suggest that some key ingredients are currently missing in our picture of planet formation. As an aside, census also indicates that planetary systems like our own, with low-mass terrestrials inside and cold giants outside, are likely rare in the Milky Way.
