Remarks

2 Dec 2015: The parent star is an eclipsing binary with an orbital period 11 d. The mass given in this page is the sum of the primary and secondary masses. The full parameters are:
Star A: M = 1.22 ± 0.01 MSun, R = 1.79 ± 0055 RSun, T = 6210 u 100 K
Star B: M = 0.97 ± 0.0039 MSun, R = 0.966 ± 0055 RSun, T = 5770 u 125 K

Remarks

02 Dec 2015: Three planetary transits have been observed as of Dec 2015, two for the primary star, the third one at the time of eclipse of the parent eclipsing binary star.   The planet revolves around an 11-day period eclipsing binary   (Kostov et al. 2015).
