It is plausile that characteristic sonic modulation of the generation of the stellar wind or the characteristic spectrum from the parent star might affect the aurorae of the planets in detectable ways. This should take place in a part of the electromagnetic spectrum that is isolatable from the overwhelming energy of the parent star's radiation.
