I’m very pleased to be able to announce that HD 80606b is a transiting planet!
It looks like priority of discovery goes Claire Moutou and the French and Swiss team, who beat at least one other team to submission by a matter of hours. I’m attaching a draft of the French and Swiss Team’s paper that was just sent to me. Congratulations to Everyone involved!
Here’s the preprint.
Details to follow…
Way cool!!
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.
Amazing. 111 day period. 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.

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

Our observations the night before show no ingress as of BJD=2454875.985, so according to their figure 1, that rules out b < 0.75 and a total duration of less than 13.2 hours.
Also, the fact that the transit must occur so late strongly suggests a spin-orbit misalignment as their RM measurements can’t be symmetric.

Congrats to Claire Moutou and co-authors!
I mean our observations rule out a total duration of **more** than 13.2 hours.
