Artist's view of an eruptive star - Flare star. Artwork - An eruptive star is a variable star that can manifest a dramatic and imforeseeable increase in luminosite from a few minutes to a few hours. From X-rays to radios, the spectrum increases in intensity. Eruptive stars are red dwarves, although recent research indicates that brown dwarves may also be capable of eruptions. A flare star is a variable star which can undergo unpredictable dramatic increases in brightness for a few minutes or a few hours. The brightness increase is across the spectrum, from X - rays to radio waves. Flare stars are dim red dwarfs, although recent research indicates that brown dwarfs might also be capable of flaring
