- Abstract
We present a uniform analysis of the atmospheric escape rate of Neptune-like planets with known radius and mass. We find that nearly 15% of Neptunes exhibit extremely high mass-loss rates, that defy evolution and composition models of their atmospheres. We conclude that at least one of the established techniques to constrain the size or mass of exoplanets is consistently producing biased values for Neptune planets.
