Did we have a dedicated Kepler-16 thread, I didn't find one?
Question as to why Kepler-16b is on a near-circular orbit (e=0.0069) when the inner binary is eccentric (e=0.16)
The curiously circular orbit of Kepler-16b
http://arxiv.org/abs/1308.0596Attempts to model the planet's migration through the circumbinary disc - need a massive disc in which the planet does not open a significant gap. Still further effects to incorporate into the model though.
