Eccentricity 0.045 ± 0.024
ω
Tperi
Radius 0.973 ± 0.03 RJ
Inclination 88.7 +1.3-1.3°

Remarks

17 Mar. 09:Fernandez et al 2009 find a period which "differs by 2.5 from previously published period. More data are needed to tell whether the period is actually variable (as it would be in the presence of an additional body) or if the timing errors have been underestimated."
