No remarks

Furlan et al. (2017) report two faint optical companions 0.045 and 3.248 arcseconds away (17.3 and 1250 AUs at 385 pc). Estimated luminosity for the latter companion seems compatible with a T-type brown dwarf (L ~ 5.3e-05 L_Sol), whereas the formes is possibly an ultracool M or L dwarf.
Michel & Mugrauer (2024) do not detect these companions but report a way farther (a = 5003 AUs) M dwarf secondary star.
