WDS 04242+1445 HDS 564 (V895 Tau) : NOTES
 
 
discov_num notes refcode
HDS 564 1991.8992: Noted as a possible spectroscopic binary by Griffin et al. Grf1988
(1988), it is uncertain whether the system we detect here is also
producing the radial velocity variation. Msn1993a
Hipparcos identified the pair as a candidate for Hyades membership. HIP1998
The spectroscopic solution of this ~42000-d pair determined by Griffin, Grf2012b
its gamma velocity "removing any remaining doubt about the systems Grf2013c
credentials as a Hyades member."
