The A and B stars are both K-type main-sequence stars, both somewhat smaller and cooler than the Sun. The two are gravitationally bound and separated at 310 AU. The binary semimajor axis is 390 AU.[1]
The third star in the visual triple, BD−06°3533, is a physically unrelated background star.[2]
Properties
HD 106515 AB is a wide binary system which was first observed by Jérôme de Lalande in 1795.[2]
The discovery of HD 106515 Ab was announced in a preprint submitted on September 12, 2011.[3] The discovery was made using radial velocity measurements obtained at the CORALIE spectrograph located at La Silla Observatory.[1] Confirmation of the discovery was made by a separate team using the Galileo National Telescope at the Roque de los Muchachos Observatory on the island of La Palma in the Canary Islands, Spain.[4] Initially announced as an exoplanet,[3] astrometric observations in 2021 have found that the true mass is significantly higher than its minimum mass predicted from radial velocity, so it is likely a brown dwarf.[5] A 2022 study found a true mass closer to the minimum mass, but the parameters are less well constrained.[6]
