Stormy ‘Space Weather’ for M-dwarf Planets?

Proxima Centauri b, that highly interesting world around the nearest star, is about 0.05 AU out from its primary.
The figure leaps out to anyone new to red dwarf stars, because it’s so very close to the star itself, well within
the orbit of Mercury in our own system. But these are small, dim stars compared to our Sun, and hugging the star
is essential to remain in the habitable zone. That also makes for very short years — Proxima b completes an orbit
every 11.2 days.
