A planetary system?
Back in 1991 Duquennoy & Mayor reported the possible presence of a low-mass object (of likely substellar nature) orbiting the red giant 13 Bootis. They set a minimum mass of 30 times that of Jupiter (likely a brown dwarf) and estimated an orbital period of 1.35 years. So far there has been no confirmation about the presence a substellar object.
