Veramendi & Gonzalez (2014) provide an orbital solution for binarity of Mu Lup C but no mass estimate for the secondary component. However modelling of radial velocities points to a substellar mass for the secondary well below the H-D burning limit (m_Cb sin i = 37 M_Jup). Tokovinin (2018) confirm this mass estimate.
Semimajor axis estimate for a host star's mass of 2.31 M_Sol.

Tertiary component of a quadruple system whose two inner components are separated by 1.1 arcseconds (98 AUs at 89 pc). The tertiary star lies 23.3 arcseconds away (2073 AUs at 89 pc), however it is not excluded that the star is actually unrelated and farther away (119 pc).
