A: sig Sco = 20 Sco = Alniyat. This system is comprised of a 33d SB |
|
|
components Aa1 and Aa2), with a third component (Ab) at 0.4" from the |
|
|
spectroscopic pair and a fourth component at about 20". The primary |
|
|
is a beta Cep variable. |
|
|
North et al. derive masses of 18.4 +/- 5.4 and 11.9 +/- 3.1 Msun for |
Nor2007 |
|
the two spectroscopic components; spectral types for the primary and |
|
|
secondary appear to be B1III and B1V, and the age is about 10Myr. |

|
1976.471: These measurements cannot be that of the SB system observed |
|
|
by Struve et al. (1961 ApJ, 133, 509) but probably relates to the more |
|
|
distant companion observed by Nather et al (1974) at a lunar |
Chu1974 |
|
occultation. The system is also a photometric variable. |

Aa1,Aa2: Malkov et al. (2012) derive dynamical, photometric, and |

|
spectroscopic masses 56.66 +/- 21.97, 15.64, 16.98 Msun, respectively. |
