discov_num notes refcode
MKT 6 zet Aur = Saclateni. The first of the zeta Aurigae-type binaries (K4IB
+ B5V). This object was misidentified as rho Aur by McAlister (1978). McA1978c
Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
Wright (1970). Wri1970
Bennett et al. (1996) orbit is combined solution, using astrometry MkT1996
from the Mark III interferometer, spectroscopy from HST Goddard High
Resolution Spectrograph, and published photometry to determine masses,
radii, etc. Positions of component stars on theoretical H-R diagram
are compared to current evolutionary models.
Errors to individual measures are given as "error ellipses"; these
values are tabulated below, together with filters used. The columns
include date (BY), major and minor axes of the ellipse (in mas),
ellipse orientation (deg), and filter effective wavelengths (nm):
