| flare star (flâr) Pronunciation Key
A variable star that sporadically displays sudden increases in brightness, sometimes becoming six times as bright in a matter of only a few minutes, after which it gradually fades back to its normal brightness. The cause of this phenomenon is thought to be an event similar to a solar flare, but on a more intense scale with a much higher emission of x-rays. |
