STFA 16 A: the 2 Ori A = 43 Ori. Spectroscopic binary, P = 21d.
B: the 2 Ori B = BD-05@ 1320.
C component is primary of 05355-0525 S 490.
STFA 17 AD: This is the the 1 / the 2 Ori system
D component = C component of 05353-0523 STF 748.
CHR 249 The A component (CHR 249 Aa,Ab) was resolved on 3 occasions, but the
distant STFA 17B component was observed to be single. Hipparcos HIP1997b
results confirm the Aa,Ab pair. The spectral classification for Lev1991b
the B component is from Morrell & Levato (1991). Msn1998a
Classification of the C component is from Hoffleit et al. (1983). Hof1983
GVT 2 Ac is a 8-12 solar mass companion. Gvt2018
GVT 2 Bb is a 1.6 +/- 0.7 solar mass companion. Gvt2018
GVT 2 Cb is a 1.7 +/- 0.2 solar mass companion. Gvt2018
