| has gloss | (noun) a red dwarf star in which luminosity can change several magnitudes in a few minutes flare star |
| has gloss | eng: A flare star is a variable star which 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 (V1396 Cygni and AT Microscopii) 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 (using the abbreviation UV) in variable star catalogs such as the General Catalogue of Variable Stars. Flares can happen once every few days or in the case of Barnard's Star much less frequently. |

| has gloss | cat: Una estrella fulgurant és una estrella variable que pot experimentar dramàtics augments impredictibles del seu esclat dalguns minuts o unes poques hores. Lesclat augmenta en tot l'espectre, des dels raigs x a les ones de ràdio. Les estrelles fulgurants son febles nanes vermelles, encara que recents investigacions indiquen que les nanes marrons podrien també produir fulguracions. |

| has gloss | fin: Flare-muuttuja tai UV Ceti-muuttuja on punainen kääpiötähti, jossa tapahtuu nopeita leimahduksia, "flareja". Ne ovat Auringon tavallisia flare-purkauksia huomattavasti voimakkaampia ja niiden syntymekanismi saattaa olla erilainen kuin Auringolla. Flaretähtiä merkitään muuttuvien tähtien luetteloissa lyhenteellä UV. |
