HJ 4962 | Central star of cluster NGC 6383, and spectroscopic binary, P = 3.37d | |
ISO 5 | Our single observation appears to indicate a single star, so we cannot | |
HDS2480 | confirm the reported ISO 5 Aa pair. Nor did we detect the new | |
Hipparcos Aa,Ac pair, presumably due to the large magnitude difference | ||
(Delta Hp = 3.2). | Msn1998a | |
Classifications of the Ab and Ac components are from Lindroos (1985). | Lnd1985 | |
Lindroos also notes a wider "X" component (V = 10.8, separation = 25", | ||
photometric classification = B5 IV) which he claims is physical. This | ||
component is not mentioned in the WDS. Lindroos finds a distance of | ||
1.8 kpc. | ||
SNA 73 | Aa1,2: The primary is V1036 Sco, an ellipsoidal variable star. It is | |
marginally resolved on two PIONIER observations with minimum | ||
separation rho>0.9mas on the first epoch and rho=10mas about one month | ||
later. The known SB2 has an equal mass ration, P=3.36d, and a sin i = | ||
14 Rsun (Stickland et al. 1993; Linder et al. 2007, A&A 474, 193. | Stc1993 | |
Given a probably distance of ~1.5kpc, the expected separation of the | ||
spectroscopic pair is <0.2mas, so we probably detected a 3rd fainter | ||
component. Mason et al. (1998) reported three other companions at | Msn1998a | |
0.27", 0.74", and 5.4". We clearly detect the wider pairs, but not | ||
Aa,Ab. The Ab companion may be a spurious detection (possibly due to | ||
the 10mas Aa1,Aa2 pair), or possibly is too faint for AstraLux and | ||
NACO, implying dm > 5mag. | Sna2014 |
