23 Dec 2011: Tha semi-majors axis is derived from the stellar radius and the ratio a/Rs given by Fressin et al. 2011. The semi-major axis derived the the stellar mass and the orbital period is 0.138 ± 0.002 AU.
The mass limit is derived from RV measurements. "Theoretical considerations give 0.66 MEarth < MP < 3.04 MEarth" (Fressin et al. 2011)
