Red Stars, Green Planets: Evaluating Planetary Habitability in Light of M-Dwarf Superflares

M-dwarf stars frequently emit high-energy flares; superflares, with energies of at least $10^{33}$ erg, are not uncommon. Repeated superflares can render planets uninhabitable, but at the same time, M-dwarfs do not emit the ultraviolet radiation that ...
