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 |
