discov_num notes refcode
HDO 150 zet Sgr = 38 Sgr = Ascella. Spectrum composite; A2III+A4IV.
Masses and bolometric magnitudes are derived for the two components
of this system by Mason et al. (1999), based on assumed spectral types Msn1999a
and available parallaxes.
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 5.24 +/- 0.37, 3.45, and 2.46 Msun, respectively. Mlk2012
H 5 78 AB,C: H V 78.
