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. |
