Remarks

19 Apr 2016: Rameau et al. (2016) "suggest that either two planets on moderately eccentric orbits or three to four planets with inhomogeneous masses and orbital properties are possible." (Galicher et al. 2014): The planet has a very red color probably due to high content of atmospheric dust.

(Rameau et al. 2013b): the semi-major axis is inferred by a projected distance of 55.7±2.5 AU.
