Notes. References can be found in Sect. 5.4. ‘...’ indicates that the multiplicity in the corresponding separation range has not been studied yet.
Detected by Sana et al. (2014) at 2.81 mas through PIONIER observations (same as spectroscopic companion).
Binary companion not detected through interferometry, but through proper motion anomaly from Gaia DR2 (Kervella et al. 2019).
Detected by Sana et al. (2014) at 0.77 mas through PIONIER observations (likely same as spectroscopic companion).
