discov_num notes refcode
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.
