discov_num notes refcode
I 422 Light and radial velocity variable.
Primary is eclipsing variable V871 Cen (period 2.0842 day). Zas2010
This is another complicated multiple system with three visual pairs at
0.36", 1.7", and 9.6". The AB pair further contains an eclipsing
binary (Otero 2007, Open European Journal on Variable Stars 72, 1;
P=2.08d) and a spectroscopic binary with a period of 2.8d (Sana et al. Sna2011a
2011). This brings the number of stars with 10" to six. It is not
currently possible to determine which component of the AB pair is the
eclipsing one and which is the spectroscopic one. Sna2014
