discov_num notes refcode
BU 1240 26 Aur. Composite spectrum; B9.5V+F9III. Light variability suspected.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Only elements P and T have been amended by Starikova (1977) from the Sta1977a
orbit of Baize (1956). Baz1956
Romero (2008) estimates masses of the A and B components as 2.1 +/- FMR2008
1.0 and 3.0 +/- 0.4 Msun, respectively; spectral types are G8III and
A1IV or B9.5V.
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 6.87 +/- 22.98, 5.45, and 4.82 Msun, respectively. Mlk2012
STF 753 Romero (2008) analyzes the optical/physical nature of the C component; FMR2008
the spectral is determined to be about A6V and it appears to be
gravitationally bound to the AB pair, with an estimated orbital period
of ~46,000 years.
AB,C: H 3 64. MEv2010
BU 90 Romero (2008) derives a proper motion for D (+0.4 +/- 2.1 mas/yr in FMR2008
RA, -12.6 +/- 1.6 mas/yr in Dec) based on that of the AB pair plus the
relative motion of AB,D between the years 1856 and 2002. He also
concludes that D is optical, with a spectral type estimated at K1III
and distance of ~870pc (both determinations corrected for reddening).
