The Habitability of Proxima Centauri b: Environmental States and Observational Discriminants

Lustig-Yaeger, Jacob; Meadows, Victoria S.; Arney, Giada N. +11 more

Proxima Centauri b provides an unprecedented opportunity to understand the evolution and nature of terrestrial planets orbiting M dwarfs. Although Proxima Cen b orbits within its star's habitable zone, multiple plausible evolutionary paths could have generated different environments that may or may not be habitable. Here, we use 1-D coupled climat…
