Remarks

9 SepT 13: data suggest that the planets and debris disk are consistent with being aligned at a level similar to the Solar System (Kennedy et al., 2013) 5 Jun 2013: The 2/1 MMR solution given here is for a coplaner inclined dynamical fit (Tan et al. 2013). Slightly different solutions are presented by Tan et al. (2013) for purely keplerian trajectories and for coplanar edge-on dynamical fits.
10 May 01: Li detected in the atmosphere of the star; interpreted as engulfment of aplanet (or planets) by the star (Israelian et al. 2001)
22 Nov. 00: From astrometry Han et al (2000) claim a preliminary mass of 36 MJ andinc
