RAT 18 BC: Initially added as 16313-2433 RAT 18AB, but the primary is also
the B component of 16312-2434 BOV 56.
BC: Spectroscopy indicates the C component is a cool substellar object
(M8-L0; Teff = 1800-2600K), not a background dwarf star, with spectral
shape indicative of young, low surface gravity planet-mass companions.
Currie et al. (2014) estimate the mass of the companion at 6-15 Mjup.
They find some evidence of an additional companion at ~0.5" of roughly
equal brightness, although preliminary analysis indicates it is a
background object. Cre2014
BC: Primary is the T-Tauri type variable ROXs 42B. Kraus et al. (2014)
estimate the mass of the companion at 10 +/- 4 Mjup. The D component
is a background star. KsA2014
