These stars lack a radiative zone, meaning that helium does not accumulate at the core and they only die when all hydrogen in the entire star is used up.
The flares of one of these objects named AU Mic have been studied in detail by the Crimean Astrophysical Observatory. Scientists recently found a rocky planet about twice the size of Earth orbiting Gliese 876, which is one of these objects. These stars lack a radiative zone, meaning that helium does not accumulate at the core and they only die when all hydrogen in the entire star is used up. Stars of this type near Earth include Wolf 359, Barnard's Star, and the closest star to Earth, Proxima Centauri, which cannot be seen without a telescope despite their proximity. Main sequence stars of K or M class, for 10 points, name this most common type of star in the galaxy, which is heavier than a brown dwarf.
