GJ 1132 b is estimated to have received at least 50 times the cumulative XUV flux of modern Earth with over 95% probability across models, supporting its classification as an atmosphere-free world.
Numerical inversion of GJ 486b's escape history shows strong degeneracy between initial hydrogen atmosphere and water inventory, yielding a probabilistic stellar age of 2.90^{+2.47}_{-2.27} Gyr when using a planet-formation prior.
Varying the adiabatic index from 1.2 to 1.4 in exoplanet evolution models shows that higher gamma produces puffier initial envelopes that contract faster with accelerated mass loss, so using gamma=1.4 overestimates mass-loss effects on young planets.

Inversion of Hydrogen-rich Atmosphere and Water Content for GJ 486b

The Effect of Adiabatic Index on Radius Evolution and the Mass Loss
Varying the adiabatic index from 1.2 to 1.4 in exoplanet evolution models shows that higher gamma produces puffier initial envelopes that contract faster with accelerated mass loss, so using gamma=1.4 overestimates mass-loss effects on young planets.
