The hypothesis that the planet transits could not be firmly discarded from our first photometric monitoring of a transit window because of the uncertainty coming from the modeling of the photometric baseline. To obtain a firm result, two more transit windows were observed and a global Bayesian analysis of the three IRAC time series and the HARPS radial velocities was performed. Unfortunately, the hypothesis that the planet transited during the observed phase window is firmly rejected, while the probability that the planet does transit but that the eclipse was missed by our observations is nearly negligible (0.26%) Objects: -------------------------------------------- RA (2000) DE Designation(s) -------------------------------------------- 05 54 04.2 -60 01 24 HD 40307 = GJ 2046 -------------------------------------------- File Summary:
