discov_num notes refcode
BSO 7 B is CPD-62@2205.
BSO 7B is the optical companion of HD 101436 (Lindroos 1985). Lnd1985
Both stars were observed and appeared to be single. Msn1998a
Additional diverse radial velocities for HD 101413 are reported by Wes1965
Thackeray & Wesselink (1965) and Conti et al. (1977). Cti1977
SNA 28 Ba,Bb: HD 101413 is a 3 to 6-month period SB2 (Sana et al. 2011), with Sna2011a
the spectroscopic companion being a likely mid-B star. The 54mas
companion is too far away and too bright to be associated with the
spectroscopic companion. Sna2014
