Abstract

This review summarizes our present understanding of the properties of M dwarf chromospheres and coronae determined from x-ray emission and ultraviolet and optical emission lines. These data permit estimates of the energy balance and heating rates for both dM and dMe stars and the presence of active regions. Two important questions are whether the dynamo is qualitatively different for the fully convective stars and whether the outer layers of dM stars are heated acoustically.
