Numerical simulation of possible surface temperatures on Proxima b (3:2 resonance)
A numerical simulation of possible surface temperatures on Proxima b performed with the Laboratoire de Météorologie Dynamique's Planetary Global Climate Model. Here it is hypothesised that the planet possesses an Earth-like atmosphere and that it is covered by an ocean (the dashed line is the frontier between the liquid and icy oceanic surface). Two models exist for the planet's rotation. Here the planet is in a so-called 3:2 resonance (a natural frequency for the orbit), and is seen as a distant observer would do during one full orbit. Another model is that it is trapped in a so-called synchronous rotation.
Two additional papers about Proxima b's possibility for habitability are described at proximacentauri.info.Credit:
