I was hoping this wasn't based on simulations but actually detected by observation. Interesting that this backs the accretion theory of lunar formation -- as against the giant impact theory.

Dan simulations might be better than observation for figuring out how these things could happen.  I am pondering if this might explain what we are seeing in Tabby’s star: a huge synestia formed recently out at a Saturn-ish radius perhaps a few thousand Saturn-ring radius.

 

If this is the right explanation, we won’t see any further dips of Tabby’s star for the next couple decades.  If it is wrong, we will see another dip in just a couple years from now, and we will again be puzzled at where the IR signature went.

 

Cool!
