M dwarfs are a type of star that is smaller and cooler than the Sun, with masses ranging from 0.08 to 0.6 times that of the Sun. They are the most common type of star in the Milky Way galaxy, making up about 70% of all stars. M dwarfs are of particular interest to astronomers because they are relatively easy to study and are thought to be key players in the formation and evolution of planetary systems. Research on M dwarfs often focuses on studying their magnetic fields, flare activity, and the presence of exoplanets orbiting these stars. Understanding M dwarfs can provide valuable insights into the nature of stars and their planetary systems, as well as the potential for habitable exoplanets.
