KUI 37 | 10 UMa. Hyad. Well observed RV variation in agreement with the visual | |
orbit. Spectral types and masses of components assigned by ten | ||
Brummelaar et al., based on adaptive optics observations. | TtB2000 | |
Calculated mass sum is 2.44 +/- 0.12 Msun, consistent with spectral | ||
types F5V. | Mut2010b | |
AB: Additional notes may be found in Duruy (1941), | Dur1941 | |
Duruy (1942), and | Dur1942b | |
Baize (1943). | Baz1943a | |
AB: Martin et al. (1998) derive component masses 1.525 +/- 0.104 and | ||
0.920 +/- 0.080 Msun. | Mig1998 | |
AB: Malkov et al. (2012) derive dynamical, photometric, and | ||
spectroscopic masses 2.37 +/- 0.33, 2.39, and 2.14 Msun, respectively. | Mlk2012 | |
AB: A typographical error in the Muterspaugh et al. (2010) orbit has | Mut2010b | |
been corrected; period is 7961.0d, not 7691.0d. Noticed by Rick Wasson | ||
(2016, private comm.) | ||
STT 566 | AB,C: Optical pair, based on study of relative motion of the | |
components using the method of apparent motion parameters. | Kiy2008 | |
