Also, the fact that the transit must occur so late strongly suggests a spin-orbit misalignment as their RM measurements can't be symmetric. http://www.astronomy.ohio-state.edu/~jdeast/demonex/HD80606b.R.2009-02-13.jpg Congrats to Claire Moutou and co-authors!

Congratulations to the French/Swiss (and Portuguese) team and also to the Systemic team that "put their money on this one" ! Luis Fantastic !

I wonder what the longest period eclipsing binary is and how 80606's period compares. I also wonder about all the studies of orbital precession that could be aided by the enormous lever arm on 80606's impact parameter. This planet is a gift from the gods. Amazing. 111 day period. I wonder what the longest period eclipsing binary is and how 80606′s period compares.

What a catch! Hats off to Moutou et al. Now to fill in the blanks on the light curve and Rossiter time series. Wow, that’s really impressive. What a catch! Hats off to Moutou et al.

Now to fill in the blanks on the light curve and Rossiter time series.
