AB: Fullerton (1990) discovered the short-period spectroscopic |
Ful1990 |
|
variation, and subsequently Wiemker (1992 MS Thesis, Georgia State |
|
|
Univ.) showed that the spectral variations are best explained by the |
|
|
superposition of a stronger stationary component and a moving |
|
|
component. Thus, the speckle resolution of this system (aka, CHR 210) |
|
|
makes clear that this is (at least) a triple consisting of a short- |
|
|
period SB1 and a distant O star. |

Aa,Ab: Mason et al. (1998, 2009) reported a companion at 23mas, but |
Msn1998a |
|
with position angles differing by 180deg. Our NACO/SAM data confirm |
Msn2009 |
|
that the correct theta value is 307deg. A closer Aa,Ab companion is |
|
|
found in the PIONIER data, with rho=28.24mas; a third AC companion is |
|
|
detected by NACO at 1.5". The primary is also reported as a 3.9d SB1 |
Ful1990 |
|
by Fullerton (1990). |

AB + SNA 60Aa,Ab + SNA 60AC: HIP 82876 is a distant O7V star. The |
|
|
0".26 AB pair was measured among other neglected binaries. We found |
|
|
another faint companion C at 1".46. The star has an extensive |
|
|
literature, including multiplicity surveys with speckle interferometry |
|
|
and RV (Chini et al. 2012). Owing to the large distance, no detectable |
Cii2012 |
|
orbital motion is expected. Indeed, the AB pair was measured with |
|
|
HRCam in 2008.5 at the same position as it is now. Those observations |
|
|
in the y band did not detect the companion C owing to a lower |
|
|
signal-to-noise ratio. |
