The Lower Main Sequence

The Lower Main Sequence. UV Ceti Stars M dwarf flare stars About half of M dwarfs are flare stars (and a few K dwarfs, too) A flare star brightens by a few tenths up to a magnitude in V (more in the UV) in a few seconds, returning to its normal luminosity within a few hours
