M Dwarf

(small, cool main-sequence star in stellar class M)

An M Dwarf is a small M-Type Star (M). The term Red Dwarf includes M Dwarfs, but sometimes also includes small K-Type Stars (K) (K Dwarfs). Early M Dwarfs (at the hotter end of the scale) are now considered likely places to observe Extra Solar Planets within a Habitable Zone (HZ), one reason being M dwarfs are very common. But given their their evolution, such planets are more likely to have experienced a longer period of stellar activity, giving it time to remove the planet's Atmosphere.

Examples include: AD Leonis (AD Leo), Barnard's Star, Lacaille 9352, Lalande 21185, Ross 154, Ross 248, Scholz's Star, and Wolf 359.
