Abstract / Description:Very recently, we were able to measure CO absorption features in the atmosphere of the non-transiting planet τ Boo b for the very first time. This allowed us to unravel a long-term mystery in planet atmosphere studies, the determination of the orbital inclination of a non-transiting planet and the exact planetary mass, respectively being 46o and 5.7 M_Jup. In light of these new results, we reanalyzed a UVES/VLT data set taken by us with the goal to detect starlight reflected from this hot Jupiter. In the previous analysis of these data, we found a candidate signal of low confidence (2σ), indicating a geometric albedo of the planetary atmosphere lower than 0.4 and an orbital inclination of 41o, which is close to the recently measured value. We reanalyzed these data by adopting updated orbital parameters and find as result that the candidate signal of marginal significance now appears at an orbital inclination of 43o.
