discov_num notes refcode
HEI 299 L722-22. Astrometric binary now resolved.
Too poor astrometric orbit (Innes 1998) and too few resolved Inn1988
observations (cf. Heintz 1990) to give definite orbit. Present Hei1990a
solution at least preferable to `X' HIP solution.
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 0.17 +/- 0.02, 0.39, and 0.50 Msun, respectively. Mlk2012
