H N 28 AB: LDS 514. B is BD-20@4123.
AB: NLTT 38872/38871 Chm2004
Proper motion of A +1034.13 -1725.45, B +987.02 -1666.69.
VLTI uniform disk diameter of A: 1.147 +/- 0.029 mas, LTI2009
VLTI limb-darkened disk diameter of A: 1.177 +/- 0.030 mas,
R = 0.739 +/- 0.019 \rsun, Teff = 4597 +/- 101 K,
M = 0.802 +/- 0.040 \msun.
B is a spectroscopic binary, P = 308d.
Statistically different parallax for the components indicates they are
non-physical.
Hipparcos triple solution together with A (= HIP 73184). P,T,e, Duq1988
omega, and q fixed from Duquennoy & Mayor (1988), cf orbit in Mar1990
Mariotti et al. (1990). Poor Hipparcos solution. Sod1999
Strand (1943) suspects a perturbation with P = 2.2y, a = 0".020, Str1943
and Omega = 30 deg.
Hyperbolic orbit by Hopmann (1967). Hop1967
sigma = areal constant in the true orbit = 2.540 arcsec^2/yr
q = periastron distance in the true orbit = 20".388
All hyperbolic orbits rejected from Fourth Orbit Catalog Wor1983
Pourbaix gives combined solution for this resolved SB2, yielding
orbital parallaxes and component masses. Pbx2000b
AF: Optical pair, based on study of relative motion of the components
using the method of apparent motion parameters. Kiy2008
Ba,Bb: Erroneously entered as BC, although C component is a very wide
companion.
Ba,Bb: Combined solution (spectroscopic/visual/parallax) by Forveille Frv1999
at al. (1999) for this low-mass interferometric SB2. P = 308.884 +/-
0.004 days, T0 = JD2450270.220 +/- 0.011. Accurate masses are
determined for these M dwarfs, as well as J, H, K, and L magnitudes.
1987.455, 1987.756, 1988.312, 1988.499: Vector separations from the 1D
data are combined to give 2D theta and rho values for these 4 dates. Mar1990
AC, AD, AE: Rectilinear solutions by Mason & Hartkopf (2016). Msn2016a
AF: Rectilinear solution by Hurowitz et al. (2014). USN2014a
