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). |
