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). |
