Red dwarfs are very-low-mass stars. As a result, they have relatively low pressures, a low fusion rate, and hence, a low temperature. The energy generated is the product of nuclear fusion of hydrogen into helium by way of the proton–proton (PP) chain mechanism. Hence, these stars emit relatively little light, sometimes as little as 1⁄10,000 that of the Sun, although this would still i… Web10 de ago. de 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.

Web5 de abr. de 2016 · A red dwarf is formed by gravitational compression and heating of an interstellar gas cloud, just like any other star.
