candidate companion

(CC)
(possible object apparently orbiting a known object)

A candidate companion (CC) is a theorized companion to a known object, something apparently orbiting it. The term is used before the presence of the companion is confirmed, or in some cases, the when a second known object is theorized to be some object's companion. For a star, such a candidate companion might be an extra-solar planet, or might be another star, such as a binary-star companion. Brown dwarfs and stellar remnants are possibilities.
