According to Vogt, we wind up with a planet with minimum mass of 2.2 times that of Earth orbiting at 0.13 AU, «solidly in the star's classical liquid water Habitable Zone.» (centauri-dreams.org)
While Star C is a much closer stellar companion of Star A than Star B, it apparently lies near the theoretical minimum mass limit of 0.75 to 0.80 Solar for core fusion of hydrogen (more from Palomar Adaptive Optics System Results). (solstation.com)
Blackman and Lucchini determined the minimum power and minimum mass flows that these accretion processes needed to produce to account for the properties of the observed jets. (sciencedaily.com)
