mu Ori = 61 Ori. Alden (1942) orbit is visual. P, T, e in Osvald's |
Ald1942 |
|
(1964) astrometric orbit are taken from a revised visual orbit by |
Osv1964 |
|
Alden (cf Osvald's paper); the revised a = 0.254". The different types |
|
|
of orbits cause the longitude of the node to be in opposite quadrants. |
|
|
Star A is an Alpha CVn variable and SB1, P = 4.45 d; star B is SB2, |
|
|
P = 4.78 d (F. Fekel 1980). |

Only elements P and T have been amended by Starikova (1977) from the |

orbit of Alden (1942). |

Combined spectroscopic/astrometric solution by Fekel et al. (2002) for |
Fek2002 |
|
the wide pair of this quadruple system, plus spectroscopic orbits for |
|
|
both short-period pairs. The solution includes mass and distance |
|
|
determinations. |

Muterspaugh et al. (2008) combine PHASES astrometry with speckle and |
Mut2008 |
|
radial velocity data to derive an orbit for the AB pair of this |
|
|
quadruple system, as well as the Aa,Ab and Ba,Bb subsystems. Listed |
|
|
solution assumes L_Aa > L_Ab and L_Ba > L_Bb; other assumptions result |
|
|
in some changes of angular elements. The parallax of the system is |
|
|
determined at 21.69 +/- 0.13 mas (distance 46.11 +/- 0.28 pc), with |
|
|
semimajor axes for AB; Aa,Ab; and Ba,Bb of 12.620 +/- 0.057, 0.07659 |
|
|
+/- 0.00058, and 0.07780 +/- 0.00036 au, respectively. Other derived |
|
|
quantities for the four components are as follows: |
|
|
Star Mass (Msun) M_K (mag) |
|
|
Aa 2.38 +/- 0.11 1.03 +/- 0.26 |
|
|
Ab 0.652 +/- 0.097 >4.58 |
|
|
Ba 1.389 +/- 0.019 1.72 +/- 0.26 |
|
|
Bb 1.356 +/- 0.019 2.02 +/- 0.26 |
