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
