CHR 262 del 1 Tau = 61 Tau = Secunda Hyadum. The primary is a long-period
BUP 55 spectroscopic and occultation binary.
Mk III Limb-darkened diameter 2.338 +/- 0.033 mas. MkT2003
CHARA Array Limb-darkened diameter 2.408 +/- 0.038 mas. CIA2009a
R = 12.3 +/- 0.4 \rsun, Teff = 4826 +/- 51 K.
This system, first announced in Mason et al. but considered of Msn1993a
uncertain veracity, has been included. While its status is not
definitive, subsequent confirmation or suspected duplicity (by another
technique) makes the discovery measurement somewhat more probable.
1991.8995: This is a particularly unexpected result, given the four
previous epochs at which our observations have shown no indications of
duplicity. All four of the earlier observations were reanalyzed using
the same procedures employed here, but no additional supporting
evidence of duplicity was found. If this additional component is
confirmed, vB 41 will be the second K0 giant binary that has been
resolved in the Hyades (HR 1411 being the other). The common proper
motion companion at a separation of 195".5 is far outside our window
of observation, and the 530-day spectroscopic component of Griffin &
Gunn (1977) would have an angular separation below the diffraction Grf1977d
limit of the KPNO 4-m telescope. Msn1993a
Aa,Ab : If real, this pair could be the 530.1-d spectroscopic binary Grf2012b
of Griffin.
