HJ 4360 Trumpler 16 MJ 238. Both A and B components were observed with the
speckle camera and appeared to be single. Levato et al. (1991) derive Lev1991a
a single-lined spectroscopic orbit for HD 93161 but they
do not indicate which component is the binary. Howarth et al. (1997
MNRAS 284, 265) and Penny (1996) found large radial velocity changes Pny1996b
in closely spaced IUE spectra, and Howarth et al. argue that both
components are short-period binaries. Msn1998a
A comp is SB, types O8V and O9V, period 8.566 +- 0.004d. Spectral type
of B component is O6.5V(f) and presents radial velocity variations. Naz2005
The position angle has been flipped about the E/W axis for the HST Nel2004
observation.
The B component is noted as SB1 by Chini et al. (2012). Both A and B Cii2012
are bright enough for an interferometric analysis of the SAM data, but
no companion was found. Sna2014
SNA 14 Ca,Cb: The C component was reported as SB1 by Chini et al. (2012). Cii2012
Further observations are desirable to confirm the reality of the tight
Ca/Cb/Cc triple. Sna2014
This star (component C of HD 93161) was observed with the speckle
camera and appeared to be single. Msn1998a
