From 2003 to 2012, the star was under observance from HARPS.
In 2012, two eccentric hot Neptune-mass planets were deduced by radial velocity. They were published in January 2013. These are close to a 1:4 resonance. The system is like HD 69830.
A third Neptune in the Venus zone was hypothesised from the data.
