discov_num notes refcode
STFA 10 AB: the 2 Tau = 78 Tau = Chamukuy. Hyades vB 72 = HR 1412.
Pair appears in an appendix list, not part of discoverer's regular
numbering sequence. B is BD+15@631.
Also variable, probably of Delta Scuti type.
The 140.7-day SB of Ebbighausen (1959 Pub. DAO, 11, 235) is outside
our detection window. Msn1993a
UBAD 2.1 relative astrometry measures computed. Table 1 mean positions USN2021
for 2017.0 and Table 2 mean dates computed as well when appropriate.
MKT 13 Aa,Ab: Data from lunar occultation, spectroscopy, and Mark III
astrometry are combined by Torres et al. to generate orbital elements. Trr1997c
Distance and component masses and absolute magnitudes are derived from
these elements.
Period is fixed for the Armstrong et al. (2006) orbit. The resulting MkT2006
component masses are 2.15 +/- 0.12 Msun and 1.87 +/- 0.11 Msun.
Aa,Ab: Orbit determined by fitting revised Hipparcos intermediate
astrometric data. Derived component masses are 2.03 +/- 0.87 and
1.78 +/- 0.76 Msun. Ren2010
Aa,Ab: Combined spectroscopic/astrometric solution, using data from
Mark III interferometer plus high-resolution spectroscopy from ELODIE,
HERMES, and CfA. Torres et al. (2011) determine an orbital parallax of Lmp2011
20.90 +/- 0.14 mas and component masses 2.86 +/- 0.06 and 2.16 +/-
0.02 Msun. Effective temperatures for both components are 7800 +/-
170K, absolute magnitues are 0.33 +/- 0.03 and 1.44 +/- 0.03 mag.
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 4.46 +/- 0.29, 3.81, and 2.00 Msun, respectively. Mlk2012
MCA 15 Ba,Bb:The primary of 04286+1558 was found to be the B component of
physical pair 04287+1552; systems were merged.
the 1 Tau = 77 Tau. Hyad (vB 71). Physical companion to the 2 Tau.
A spectroscopic, occultation, and interferometric binary.
First detected as an occultation binary by White. Wit1979
1979.698, 1979.857: possible third component Heg1983
This is a long period interferometric companion in addition to the
spectroscopic component suggested by Griffin & Gunn (1977) to have a Grf1977d
period of about 16 years. An estimate of Delta m = 0.76 was made by Dmb1991
Dombrowski (1991). Msn1993a
Masses and distance of the 2 Tau are derived from spectroscopic
elements, adopting astrometric elements from Pan et al. (1992) MkT1992e
Combined spectroscopic/astrometric solution by Torres et al. (1997). Trr1997c
Distance (from relative proper motions and orbital parallax of the 2
Tau) 47.6 +/- 1.9 pc, masses 2.91 +/= 0.88 and 1.31 +/- 0.14 Msun.
CHARA Array Limb-darkened diameter of B 2.305 +/- 0.043 mas. CIA2009a
R = 11.7 +/- 0.2 \rsun, Teff = 4811 +/- 50 K.
Ba,Bb : New spectroscopic solution determined by Griffin. Grf2012b
Ba,Bb: Malkov et al. (2012) derive dynamical and spectroscopic masses
4.14 +/- 0.35 and 2.88 Msun, respectively. Mlk2012
BPMA 7 BC: [PM2000] 171052 + [PM2000] 171309. Gvr2010
