The light curves taken so far are VERY unusual. Something interesting and unanticipated is going on at that star. Spectra of the F type star there (when nothing is happening) show a VERY ordinary F type star.
I offer an explanation that is IHMO more plausible. There is one or more super earth orbiting close near the Roche limit. At this distance the surface is likely mostly molten and the atmosphere consist of metallic rock vapor. Tidal stress is progressively but unevenly stripping the rock vapor atmosphere and distending and disintegrating the planet. Every now and then a big chunk comes off due to tidal stress, and with it a big puff of rock vapor is liberated and enter orbit around the star. Darkening occurs when a large amount of rock vapor is released, recovery occurs either as photo pressure blows away the rock vapor, or some of the vapor is accreted back onto the planet on become incorporated into the star. The lack of periodicity and the variability in the magnitude of darkening is the artifact of the chaotic nature of the gradual stripping of a planet by thermal heating and tidal stress.
Does the absorption spectrum of the star change during a darkening event?
