Abstract:
We recently reported the photometric and spectroscopic detection of
the primary transit of the 111-day-period, eccentric extra-solar
planet HD 80606b, at Observatoire de Haute-Provence, France. The whole
egress of the primary transit and a section of its central part were
observed, allowing the measurement of the planetary radius, and
evidence for a spin-orbit misalignment through the observation of the
Rossiter-McLaughlin anomaly. The ingress not having been observed for
this long-duration transit, uncertainties remained in the parameters
of the system. We present here a refined, combined analysis of our
photometric and spectroscopic data, together with further published
radial velocities, ground-based photometry, and Spitzer photometry
around the secondary eclipse, as well as new photometric measurements
of HD 80606 acquired at Mount Hopkins, Arizona, just before the
beginning of the primary transit.
