FIN 347 Aa,Ab: pi 1 Cnc = 81 Cnc.
1981.358: This observation was incorrectly attributed to ADS 7158 by Tok1982a
Tokovinin (1982a) (noted in Tokovinin 1982b) Tok1982b
1983.9371, 1983.9372: Interferometric observations indicate that Wor1983
Finsen's 1965 orbit (see Worley & Heintz, 1983) must be revised. Bnu1984
1990.9166: Residuals (4.0 deg in theta, 0".007 in rho) to the orbit of
Hartkopf (1989) are only fair, due to a combination of large zenith Hrt1989
distance and close angular separation at the time of this observation.
A combined astrometric/spectroscopic orbital solution is given by
Mason et al (1996). Msn1996a
Reversed Delta m and slightly larger parallax/smaller masses than in Msn1996a
the speckle-spectroscopic study by Mason et al.(1996).
Pourbaix gives combined solution for this resolved SB2, yielding
orbital parallaxes and component masses. Pbx2000b
Aa,Ab: Combined solution orbit. Mass_a = 0.983 +- 0.045 Msun,
Mass_b = 0.903 +- 0.049 Msun, orbital parallax = 48.78 +- 2.36 mas. Msn2012a
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 1.80 +/- 0.25, 1.86, and 0.91 Msun, respectively. Mlk2012
BUP 125 AB: Due to the high proper motion of the A component, a later
observation of this pair by Soulie was incorrectly entered as a new Sle1986a
component, SLE 478AD.
STT 569 AC: Optical pair, based on study of relative motion of the
components using the method of apparent motion parameters. Kiy2008
WIL 1 AE: CPM pair. Using data from 2MASS, Wilson et al. (2001) derive a Wil2001
spectral type of L8V and mass 40-74Mjup for the companion (called
Gl 337C in that paper). They also note that the C and D components for
the system appear to be background objects without CPM to the AB pair.
BUG 16 Ea,Eb: Burgasser et al (2005) resolved the E component (called Gl 337C
in the paper) into a 0.53" pair of near-equal magnitude. At a distance
to the system of 20.5 +/- 0.4pc, the close pair has a physical
separation of 10.9 +/- 0.6 au. Period of the pair is estimated at
140-180y. Primary is L8; secondary is possibly early- or mid-T dwarf. Bug2005
