Furlan et al. (2017) report up to three companions 0.108, 2.38 and 3.918 arcseconds away (28.6, 630 and 1038 AUs at 265 pc). Estimated luminosities suggest the innermost companion to be likely a fainter M dwarf and the outer ones, if confirmed, as possible L to T-type brown dwarfs.
Sullivan et al. (2024) confirm the stellar companion 0.11 arcseconds away, whose most likely spectral type is M5V.
