| FIN 342 |
Aa,Ab: Hyad (vB 57). HR 1391 = 70 Tau. |
|
|
Combined spectroscopic/astrometric solution. Orbital parallax 0.02144 |
Trr1997b |
|
+/- 0.00067, masses 1.363 +/= 0.073 and 1.253 +/- 0.075 Msun. |
|
|
Quadrant determinations made at several epochs by McAlister et al. |
McA1988 |
|
(1988) have shown that this system is best represented by an eccentric |
|
|
orbit of period 6.3 years, rather than a circular 13-year orbit. |
|
|
1977.7421 Theta was incorrectly given as 6.0 degrees by McAlister & |
|
|
Fekel 1980). |
McA1980b |
|
This resolved spectroscopic binary (with P = 6.28 yr) is discussed by |
McA1988 |
|
McAlister et al. (1988) and by Dombrowski (1991). |

The published measure for 1988.6582 (McAlister et al. 1990) is |
McA1990 |
|
is spurious. The data leading to this measure are actually the same as |
|
|
those for HR 1331 (= McA 14) for the same epoch. These two stars were |
|
|
observed in immediate sequence but with different microscope |
|
|
objectives, and the final reductions calculated two results from the |
|
|
same data set, but with different scale factors; the HR 1331 measure |
|
|
for 1988.6582 is the correct one. Reanalysis of the correct data for |
|
|
FIN 342 gives the 25 mas result shown here. Peterson (1992, private |
|
|
communication) pointed out the inconsistency of our originally |
|
|
published measure with respect to our previous orbital analysis of |
|
|
this Hyades binary (McAlister et al. 1988). |
Hrt1992b |
|
Pourbaix gives combined solution for this resolved SB2, yielding |
|
|
orbital parallaxes and component masses. |

Aa,Ab : New spectroscopic solution determined by Griffin. |
Grf2012b |
|
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and |
|
|
spectroscopic masses 2.50 +/- 0.47, 2.48, and 1.13 Msun, respectively. |
