RMK 16 the Mus. Wolf-Rayet binary, second brightest in the sky.
The classification is from Houk & Cowley (1975 Michigan Spectral
Catalogue, vol. 1). Moffat & Seggewiss (1977 A&A 54, 607) found
evidence of orbital motion in the WR star, but the O star appeared
stationary. We found a possible binary companion at a separation of
0".04 which needs confirmation, but if correct, this suggests that the
system is triple, consisting of a WR SB1 plus a distant O star. The
visual B component was observed and appeared to be single. Msn1998a
The primary is the WR+O spectroscopic binary theta Mus = WR 48. B is
reported as SB by both Chini et al. (2012) and Sota et al. Cii2012
(2014, ApJS 211, 10). Sna2014
