Otherwise, the transition region is the place to be. By the way, the average equilibrium temperature of Proxima b is estimated to be something like -30°C, far below freezing, and would have to be lifted to nice levels by the greenhouse effect. The same happens on Earth as well, albeit to a slightly lesser degree.
There's no mention of its possible mass in the articles I've read, but it seems to me that orbiting so close, and so quickly, it cannot have that much to it -- meaning it might have trouble retaining an atmosphere.
