COO 157 A semiregular variable, V766 Cen.
CSU 1 Aa,Ac: Chesneau et al. (2014) imaged a close companion to the
supergiant V766 Cen, using VLTI/AMBER. Based on visual photometry,
they estimate the orbital period at 1304 +/- 6d. Csu2014
Wittkowski et al (2017) used VLTI/PIONIER for followup H-band imaging.
At the 2014 epoch they believe the companion was behind the primary.
They conclude the companion is most likely a cool giant or supergiant
with a mass ~5 Msun. Wtk2017
