SEE 334 AB: lam Sco = 35 Sco = Shaula. Variable. Spectroscopic binary.
TNG 1 Aa,Ab: The combined solution orbit by Tango et al. (2006) determines Tng2006
component masses of 10.4 +/- 1.3 Msun and 8.1 +/- 1.0 Msun. There is
also a pre-MS subcomponent to A with a mass of 1.8 +/- 0.2 Msun. The
dynamical parallax is 112 +/- 5 mas, about a factor of two smaller
than the Hipparcos value of 216 +/- 42. The dynamical value is much
more accurate. Two components have calculated effective temperatures
of 25000 +/- 1000 and 21000 +/- 1000 degrees Kelvin, respectively.
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 77.47 +/- 30.56, 22.63, 10.96 Msun, respectively. Mlk2012
