126 Tau. The variable radial velocity indicates a spectroscopic |
|
|
subsystem; the RV range of the blended light is about 50 km/s. |
|
|
Single night's measure in 1960 apparently does not refer to this pair. |
|
|
Observed delta m definitely larger than given in ADS. |

Malkov et al. (2012) derive dynamical, photometric, and spectroscopic |
|
|
masses of 17.71 +/- 23.89, 9.78, and 6.41 Msun, respectively. |
