Known red dwarf stars

WebAug 10, 2024 · Red dwarf stars — also known as M dwarfs — comprise about 75% of all stars in the Milky Way. They’re much cooler and smaller than the Sun and, since some of them lack the internal layers that Sun-like stars have, their churning guts and fast rotation make them prone to extreme magnetic activity, such as flares. The spectral standards for M type stars have changed slightly over the years, but settled down somewhat since the early 1990s. Part of this is due to the fact that even the nearest red dwarfs are fairly faint, and their colors do not register well on photographic emulsions used in the early to mid 20th century. The study of mid- to late-M dwarfs has significantly advanced only in the past few decad…
