Tabby’s Star

Apparently the riddle of Tabby’s Star has been solved, the weird light fluctuations (which aren’t due to alien megastructs, if they were we would only be seeing infrared due to waste heat emissions, instead the patterns are consistent with those of dust) are due to tidal disruptions of an icy exomoon of a planet orbiting Tabby’s Star. In other words, an exomoon is being shred to bits by the star itself and the resulting chaos is what’s causing the dimmings.

Similar explanations have been proposed for the other oddly dimming stars out there, just how common is this phenomenon of moonnapping?

Note that this is only preliminary, further research is needed, and that such a coincidence could explain these odd dimmings seems unlikely.
