news. There are three epochs missing in the data I sent you. My code had a bug where it cut them off, but I have fixed it now. So you have 3 new transits to add in.

Interesting news: The priority of the two solutions that I mentioned in the previous email switched with the new data. Now, the solution with a smaller planet near 5:3 gives chi2$=$5.8 (!) for 8 degrees of freedom. This one improved enormously. The solution with the Jupiter-mass planet near 5:2 now gives chi2=28.9, and can be rejected.

I am starting to be confident that we have finally obtained the correct and unique solution.

To summarize: In all likelihood we have here a system of two planets, the outer non-transiting planet should have mass about 25% lower than Saturn. It should be near the 5:3 resonance (period ratio 1.6967), low eccentricities and low inclinations.

We had 15 transits of KOI-872b and things were converging toward the solution near the 5:3 resonance, which is the correct one. And our excitement was building up...

Woah - that’s a hell of a fit!

Transit wise -
