Erik Petigura kicks off Day 3 of #exoplanets5 with exoplanet demographics.

Erik draws a parallel to stellar „demographics“ as seen in the HR diagrams and how our view of the stellar population with sample size.

Looking at the period distribution we see that Jovian planets are a lot less common than super-earths. We also see a 3/4 day pile up.

If we look at metallicity we see that small and distant planets form around any kind of metallicity star while giants and close-in prefer high-met.
