That is definitely quite bizarre. But it's amazing that they can actually figure this out from groundbased observations....

So, when will we have this modeled in Celestia? It would be a very interesting stop in a tour of the universe!

Gravity darkening, eh? That is interesting... it is also oppositee i effect to the emission disk supposedly surrounding Be or B-emission stars like Dschubba or Achernar

in Be stars, the spin supposedly flings out a disk around the equator which is brighter than the star;
Dscubba for example is brighter when the disk is larger and so on.

Anyone know anything about this?

Regulus is darker around the equator, because the gravity is weaker at the equator, and the star is less copmpressed apparently.
