Planetary radius vs stellar age diagram of evaporation (H and He I) detections (blue circles), non-detections (red crosses), and non-conclusive observations (orange down-pointing triangles). Planetary radii and stellar ages are from Table M.1. The top panel shows the summed histogram of evaporation detections (blue line) and non-detections (red line) across stellar age. The grey points represent all known planets with radius and age determined with precision better than 30% and 50%, respectively (data from NASA Exoplanet Archive).
