JEF 1 |
bet CrB = 3 CrB = Nusakan. A spectroscopic binary resolved visually, |
|
|
and avariable of Alpha CVn-type. |
|
|
1973.22, 1973.45: See discussion and orbital elements by Labeyrie et |
|
|
al. (1974). |
Lab1974 |
|
1975.383, 1975.455: The observations presented here are of poor |
|
|
quality but the results are consistent with those of Labeyrie et al. |
|
|
and McAlister. |
BLM1978 |
|
1980.4682: See preliminary elements and discussion in Balega et al. |
|
|
(1984). |
Bag1984b |
|
1983.3206: A peculiar SB with a 10.5-year period. |
Bag1984a |
|
1984.1867 and other observations through 1985.2440: The speckle |
|
|
interferometric observations are in good agreement with both Balega et |
Bag1984b |
|
al. (1984) and Tokovinin (1984) orbits; radial velocity measurements |
Tok1984 |
|
are strongly needed to improve the spectroscopic orbit of this system. |
Bnu1986 |
|
Measure of 1988.256 made by MAPPIT. |
Naj1989 |
|
The speckle observations and derived masses leave no room for a |
|
|
conjectured third component, cf. Kamper et al. (1990). |
Kpr1990 |
|
Hipparcos astrometric solution adopted some elements from the orbit of |
HIP1997d |
|
Kamper et al. (1990). |
|
|
Based on combined observations from VLT/Naco and CHARA/FLOUR, Bruntt |
|
|
et al. (2010) derive the following parameters for the components of |
Bnt2010 |
|
bet CrB: radii 2.63 +/- 0.09 and 1.56 +/- 0.07 Rsun, spectral types A5 |
|
|
and F2, luminosities 25.2 +/- 2.9 and 4.5 +/- 0.05 Lsun, Teff 7980 +/- |
|
|
180 and 6750 +/- 230K, masses 2.09 +/- 0.15 and 1.40 +/- 0.10 Msun. |
|
|
The age of the systems is estimated at 0.53 +/- 0.10 Gyr. |
|
|
Combined spectroscopic/astrometric solution of SB1. Radial velocities |
|
|
span nearly a century. Calculated masses 1.71 +/- 0.18 and 1.330 +/- |
|
|
0.074 Msun. |
Mut2010b |
|
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic |
|
|
masses of 3.08 +/- 0.24, 4.09, and 3.17 Msun, respectively. |
