HD 208727 is a suspected member of the enigmatic MAIA variables and shows the largest yet observed amplitude in light variation for any of the potential members. Proven beyond doubt pulsation would pose a serious problem for stellar modelling and opacities, because either opacity source for driving pulsation has to be a different or new identified, yet unkown, pulsation mechanism. We conclude from our investigation that rotation is a more likely explanation for the light variability of HD 208727.
