13 Sep 2011: Planet Gl 581 g not found by Forveille et al. 2011 either with keplerian fit or circular orbits for Gl 581 b,c,d,e
02 Nov 2010: Anglada-Escude (2010) investigates the degeneracy deriving from the aliasing of eccentric harmonics of an already detected planet and finds that "though the statistical degeneracy is clearly present, the existence of GJ 581g remains well supported by the available data".
