COU2431 Aa: First resolution of primary, which was a known SB (period 112d).
Metallicity estimates range from -0.78 to -0.14. Hor2012b
LSC 1 Aa1,2: Docobo et al. (2014) use the spectroscopic elements of Goldberg
et al. (2002 AJ 124, 1132), together with speckle data and Hipparcos
parallax, to derive the remaining orbital elements. The resulting
masses are 1.05 +/- 0.05 and 0.89 +/- 0.05 Msun. Doc2014h
Aa1,2: SB2, P=112.56d Tok2014d
LEP 98 AD: SHY 337. Bayesian analysis by Shaya & Olling (2011) indicates very Shy2011
high (near 100%) probability pair is physical.
SEI1363 CR: Also known as BUP 221CR or LDS2480.
NLTT 50309 Combined spectroscopic/astrometric solution, based on high-resolution
echelle spectra plus archival PTI visibility measurements.
Derived masses 1.1861 +/- 0.0057 and 0.9407 +/- 0.0049 Msun,
distance 40.571 +/- 0.052 pc. Knc2010
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses 2.18 +/- 0.15, 2.37, and 1.10 Msun, respectively. Mlk2012
HDS2989 Da,Db: Previously known as 20582+4011 HDS2989AB, but found to be the D
component of the CPM pair LEP 98.
Da,Db: Rectilinear solution by Hartkopf & Mason (2013). Hrt2013b
