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. |

B is BD-07@4426. |
