eta Vir = 15 Vir = Zaniah. A spectroscopic and occultation binary now |
|
|
resolved by speckle interferometry. |
|
|
Observed parallax corroborates closely the orbital value given by |
|
|
Hartkopf et al. (1992). Primary is 72d SB2 (#718 in Batten et al., |
Hrt1992a |
|
1989). This is not the SB2 because the observed angular separations |
Bte1989 |
|
are much larger than the 12 mas maximum predicted by Halbwachs (1981) |
HJL1981 |
|
from the spectroscopic elements. See discussion in Balega et al. |
Bag1984b |
|
(1984), who give preliminary orbital elements based entirely on |
|
|
speckle observations. |
|
|
1985.2053, 1985.2491: These measures agree well with the preliminary |
|
|
orbit of Balega et al. (1984), who adopted a period of 13 years. The |
|
|
orbit proposed by Tokovinin (1984) with P = 9.8 years fails to fit the |
Tok1984 |
|
speckle observations. |

See Baize & Petit (1989) catalog of doubles with variable component. |
Baz1989d |
|
A new speckle/spectroscopic orbit of the early A type triple system |
|
|
eta Vir has been determined by Hartkopf et al. (1992). |
Hrt1992a |
|
Martin et al. (1998) derive component masses 6.009 +/- 2.164 and |
|
|
0.673 +/- 0.800 Msun. |
