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 |
