94 Aqr. A is a long-period spectroscopic binary now resolved by |
|
|
speckle interferometry. |
|
|
Soderhjelm give triple solution with B (HIP 115125) instead of poor |
Sod1999 |
|
Hipparcos solution. The primary is overmassive, probably sp. bin., |
|
|
cf. analysis of the spectroscopic/interferometric orbit by McAlister |
|
|
& Hendry (1982) |
McA1982c |
|
Analysis of this observation by the techniques in use in 1985 was |
|
|
unable to yield a useable result. |
Hrt1992b |
|
1977.6350: This epoch was incorrectly given as 1977.6359. |
McA1982b |
|
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and |
|
|
spectroscopic masses 1.55 +/- 0.87, 1.98, and 1.20 Msun, respectively. |
