Avalanche statistics suggest Tabby's star is near a continuous phase transition
PS> Having to wait 20 seconds between searches on this forum really sucks.
This is the most promising gesture in the direction of an explanation to date. What would make it more than a gesture is a phase transition mechanism. Likely it is some variant of the ionization transition that drives normal periodic variables. A rare peculiarly of dynamics and geometry could disturb the reformation of the ionization layers and break the periodicity.
It's a brilliant idea. I wish I'd thought of it.
The color represents displacement not temperature
Now there is another hypothesis:
"The slow dimming of Tabby’s star and the sudden dips in its light may be caused by an orbiting cloud of debris left over from when it partially gobbled a planet."

You need to get the area of the star blocked from view by the orbiting junk to vary....
