Hydrogen loss from Proxima b for different XUV prescriptions.
| XUV prescription | H loss (EOH) | ||
| HZ (1.5 S⊕) | HZ (0.9 S⊕) | Lifetime | |
| 90 Myr | 200 Myr | 4.8 Gyr | |
|
|
|||
| Eq. (2) | 0.47 | 0.90 | 15.6 |
| Eq. (3) | 1.07 | 1.98 | 24.4 |
Notes. The following assumptions are made: the initial time is 10 Myr, the mass and radius of Proxima b are 1.3 M⊕ and 1.07 R⊕, respectively, and the initial water content is considered infinite.
