STF2308 |
AB: LDS1882. HJL 257. Statistically the same parallax within the |
HJL1986 |
|
errors would indicate the components are physical. |
|
|
Linear elements fit nicely at present, but this is a physical pair and |
|
|
an orbit can be computed at some future date. |
|
|
AB: H 4 67. |
MEv2010 |
|
AB: A,B are 2.6 mag above MS, both evolved, both SB systems. Orbital |
|
|
parallax 23.0+-2.2mas. Masses 1.39,1.30,1.32,1.20. |

BAG 6 |
A: 41 Dra. Spectroscopic binary, P = 1247.2d, with the highest known |
|
|
eccentricity to date, e = 0.975. |
|
|
Elements P, T, and e for the Balega et al. (1997) orbit were adopted |
Bag1997a |
|
from the spectroscopic orbit of Tokovinin (1995). |
Tok1995b |
|
Combined spectroscopic/speckle solution by Tokovinin et al. (2003), |
Tok2003 |
|
deriving masses (1.28 +/- 0.15, 1.20 +/- 0.14 Msun) and orbital |
|
|
parallax (23.0 +/- 2.2 mas). Authors note earlier elements and discuss |
|
|
possibility of orbital evolution. |
|
|
Effective temperatures for the two components are 6370+/-20 and |
|
|
6410+/-20K, log g 4.05+/-0.10 and 4.20+/-0.10. Abundances for both |
|
|
components are very near solar. |
Bag2005b |
|
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and |
|
|
spectroscopic masses 7.75 +/- 5.22, 3.34, and 2.24 Msun, respectively. |
Mlk2012 |
|
B: 40 Dra = BD+79@570. B is also a spectroscopic binary, P = 10.53d. |
