discov_num notes refcode
SNA 26 The primary is V1051 Cen, a detached Algol-type eclipsing binary. A
known O+O SB2 (Gies et al. 2002; P~9.7d). Given the distance to the Gie2002
IC 2944 cluster, this additional component at 61mas is not the
spectroscopic companion, thus making HD 101131 a hierarchical triple. Sna2014
