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 ...

Radio detection of late-type (G-K) dwarf stars in the Pleiades

, 1995
We report deep 3.6 cm radio observations of a small sample of the most rapidly rotating G-K dwarf stars in the Pleiades. Of the four ultrafast rotators (UFRs) observed, three were detected.
