Both spectra are visible. |
|
|
For the visual pair West (1976) computed the elements P, T, e, and |
Wst1976 |
|
longitude of periastron also from the RV's (orbit 3); tentative |
|
|
elements a, i, and the node were added by Heintz in order to have a |
|
|
complete listing in the Fourth Orbit Catalog. Since the components are |
|
|
visually indistinguishable, the quadrant of the ascending node (but |
|
|
not the longitude of periastron) is arbitrary; with the node chosen as |
|
|
listed, the close pair would be the eastern component when the visual |
|
|
pair is at maximum separation. |
|
|
The pair was long assumed to have a 12 yr period. |

1980.4853 This measure was incorrectly identified with HR 8131 = |

alp Equ in McAlister et al. (1983). |

The component with the slightly weaker lines is an SB1, P = 2.24 d. |

Malkov et al. (2012) derive dynamical, photometric, and spectroscopic |

masses of 2.60 +/- 0.44, 2.43, and 1.13 Msun, respectively. |
