| CHR 151 | Aa,Ab: This newly-discovered pair was unresolved in our earlier survey | |
| for duplicity among high-velocity stars (Lu et al. 1987). Abt & | McA1987c | |
| Biggs (1972) list a single radial velocity of -89.3 km/s for this | AbH1972 | |
| object, published in 1950. Additional observations, both by speckle | ||
| and by spectroscopy, are needed for confirmation of its duplicity and | ||
| its high velocity. | Hrt1992b | |
| B is BD-07@4426. |
