flare star
A flare star is a type of variable star that can undergo unpredictable dramatic increases in brightness for a few minutes due to intense magnetic activity. They are usually faint and are most often red dwarfs, although less massive brown dwarfs or more massive Sun-like stars can also be flare stars. The increase in brightness is believed to result from a star’s magnetic field changing rapidly, releasing vast amounts of energy in the process.

Flare star
A flare star is a variable star that can undergo unpredictable dramatic increases in brightness for a few minutes. It is believed that the flares on flare stars are analogous to solar flares in that they are due to magnetic reconnection in the atmospheres of the stars. The brightness increase is across the spectrum, from X rays to radio waves. The first known flare stars were discovered in 1924. However, the best-known flare star is UV Ceti, discovered in 1948. Today similar flare stars are classified as UV Ceti type variable stars in variable star catalogs such as the General Catalogue of Variable Stars. Flares can happen once every few days, or, as in the case of Barnard's Star, much less frequently. Most flare stars are dim red dwarfs, although recent research indicates that less massive brown dwarfs might also be capable of flaring. The more massive RS Canum Venaticorum variables are also known to flare, but it is understood that these flares are induced by a companion star in a binary system which causes the magnetic field to become tangled. Additionally, nine stars similar to the Sun have also been seen to undergo flare events. It has been proposed that the mechanism for this is similar to that of the RS CVn variables in that the flares are being induced by a companion, namely an unseen Jupiter-like planet in a close orbit.
