The stars are boiling! This is because of the energy generated in the center of the star that wants to escape. If this does not happen quickly enough, the star starts to 'boil' in the outer layers causing vibrations that result in light variations, like in the Sun. Such oscillations have now been discovered, but in a much hotter star.
