Exoplanet Demographics: Population Statistics of Hot Super-Earths and Cold Jupiters – Gijs Mulders

Exoplanets are a diverse population reflecting the range in possible outcomes of the planet formation process. Yet there are also patterns in the demographics of exoplanets with certain types of planets and planetary systems being much more common than others.
In this talk I will paint a consistent picture of exoplanet demographics consisting of two main planet populations: hot super-Earths and cold Jupiters. These exoplanet populations are constrained by transit, radial velocity, direct imaging, and micro-lensing surveys. I will place these results in the context of the solar system, showing that it is neither an extreme outlier nor a typical system.
While some stars have both hot super-earths and cold giant planets, other stars have only one or the other, highlighting the variety of planetary systems architectures. The demographics of these planetary systems is still in its infancy but provides new ways of understanding how planets form and why the solar system — with cold giant planets but lacking close-in super-earths — looks the way that it does.
