A Statistical Comparison of Exoplanet and Protoplanetary Disk Properties The Kepler survey has shown that exoplanets smaller than Neptune are extremely common and can be found around a wide variety of stars. Combined with large surveys of star forming regions, it becomes possible to connect the population of exoplanets to the protoplanetary disks in which they form. In this talk, I will explore the relations between exoplanets and their host stars, in particular how planet occurrence rates depend on stellar mass and metallicity. Most surprising, planets occur more frequently around low-mass M dwarfs than around sun-like stars, in contrast to the lower protoplanetary disk masses observed with ALMA for low-mass stars. These results indicate that inward migration of planetary building blocks plays a crucial role during planet formation, and that planets in protoplanetary disks form early and efficiently. I will highlight the areas where the census of disks and exoplanets is incomplete and where current and future surveys can map this terra incognita.
