Cold Planet Demographics from Microlensing and Radial Velocity Surveys

I present a preliminary analysis of cold planet demographics using results from gravitational microlensing and radial velocity surveys. Unlike published exoplanet demographics analyses, I present microlensing results using host star mass measurements and limits, so the host mass dependence of the exoplanet distribution can be measured. The combination of microlensing and radial velocity surveys allows us to take advantage of the wide range of orbital separation sensitivity from the radial velocity data and the sensitivity down to low masses with the microlensing data.
