Remarks

19 Nov 2010: The star is on a higly eccentric galactic orbit, with a distance from 7 to 16 kpc and claimed to be of extragalactic origin (Setiawan et al. 2010)

Remarks

29 Dec 2013: A reanalysis of RV data by Jones & Jenkins (2014) leads to retract this planet candidate.
19 Nov 2010: Personal note (JS): the extra-galactic origin of the star does not prove that the planet b is also of extragalactic origin.
