Planetary system
In 1998 the California and Carnegie Planet Search team, after following a suggestion by Kevin Apps, a Briton who at the time was an undergraduate student found a possible planet orbiting the star. There were also indications of another, more distant body orbiting the star and this claim was published in 2006. This planet was confirmed in 2009.
