Measures of Kulagin made by a transit interferometer; quadrants were
flipped for all his measures. Kul1970

Combined spectroscopic/interferometric orbit by Heintz (1974): Hei1974a
P = 104.0237 d, a = 0.0547", eccentricity neligibly small. Ascending
node revised according to Heintz's astrometry
1969.1348: This position angle was incorrectly published as 303.0
degrees in Balega & Tikhonov (1977). Bag1977
1978.915, 1978.929, 1979.082: Observations on these three dates
overlap in two papers by Koechlin et al. (1979, 1983), with only Koe1979
slight changes. Values from the later paper are given in the catalog. Koe1983
1984.9309, 1985.1062, 1985.1994: Estimates of the position angle and
angular separation are deduced from the elongation of the central
speckle peak in the autocorrelation. Bnu1986
Colors and spectral types determined by speckle photometry are
given by Bagnuolo & Sowell (1988). Bgn1988
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Observations by Hummel et al. (1994) were made through narrow band MkT1994
filters centered at 800, 550, and 450 nm. Colors were derived from all
1988-1992 data, so are listed at the mean epoch of 1991.9. This paper
also includes a new orbit. Finally, errors are given as "error
ellipses"; these values are tabulated below. Columns include date
(BY), major and minor axes of the ellipse (in mas), and ellipse
orientation (in degrees).

Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
Hummel et al. (1994). MkT1994
Pourbaix gives combined solution for this resolved SB2, yielding Pbx2000b
orbital parallaxes and component masses.
Branham (2008) derives combined interferometric/spectroscopic orbit, Bnh2008
using a semidefinite programming technique. The resulting masses are
3.049 +/- 0.513 and 2.569 +/- 0.432 Msun; he also determines a value
for the parallax of 74.85 +/- 1.53 mas.
Aa,Ab: Following an extensive review of historical spectroscopic and
astrometric measurements of Capella, Torres et al. (2009) derived a Trr2009
new combined-solution orbit, assuming a circular orbit. They determined
an orbital parallax of 76.67 +/- 0.17 mas (distance 13.042 +/-
0.028 pc), an age of 540-590 Myr, and the following physical
parameters for the two components:
Mass (Msun): 2.466 +/- 0.018 2.443 +/- 0.013
Radius (Rsun): 11.87 0.56 8.75 0.32
Teff (K): 4920 70 5680 70
Luminosity (Lsun): 79.5 4.8 72.1 3.6
Mv (mag): 0.315 0.017 0.186 0.016
Aa,Ab: Weber & Strassmeier (2011) derived new spectroscopic elements, WbS2011
assuming the period determined by Torres et al. (2009). The new Trr2009
solution yielded masses of 2.573 +/- 0.009 and 2.488 +/- 0.008 Msun.
Aa,Ab: A combined solution by Torres et al (2015) yields the following Trr2015
physical parameters for Aa and Ab:
mass (Msun): 2.5687 +/- 0.0074 2.4828 +/- 0.0067
Teff (K): 4970 50 5730 60
Radius (Rsun): 11.98 0.57 8.83 0.33
log g (cgs): 2.691 0.041 2.941 0.032
Luminosity (Lsun): 78.7 4.2 72.7 3.6
a(AU): 0.74272 +/- 0.00069
Distance (pc): 13.159 0.015
Age (Myr): 590-650
[Fe/H}: -0.04 0.06
HJ 2256 AF: H VI 30.
AF: Optical pair, based on study of relative motion of the components
using the method of apparent motion parameters. Kiy2008
SHY 23 AM: HIP 24608 + HIP 26779.
SHY 23 AN: HIP 24608 + HIP 26801.
MN is 05413+5329AB. Dam2017i
ST 3 Capella HL, the distant (723") double companion to Capella with
common proper motion. A premature orbit has been computed.
Capella H is variable with a period of about 17.9d and an amplitude Skf2019g
amplitude of about 0.03 magnitudes.
