I had previously discussed the amplitude of the ~0.88-day signal
of Boyajian's star (or KIC 8462852.) If you look at the amplitude series alongside gradual dimming of the star throughout the Kepler mission (Montet and Simon, 2016), it appears there's a relationship, even though amplitude changes are real and not an artifact of dimming. Montet dimming is thought to be very unique to Boyajian's star. It follows that if the 0.88-day signal is independent of major dips, our peculiar star happens to be affected by two unique but independent mechanisms.
