alp Cen = LDS 494 = Rigel Kentaurus. C is Proxima Centauri = V645 Cen. |
|
|
According to R.G. Aitken, this was discovered by |
A__1935f |
|
Father Richaud while observing a comet at Pondicherry, India, in |
Rhd1729 |
|
December 1689. P= 79.9y, a = 17.52", motion direct. Due to the |
|
|
proximity of the pair and the eccentricity of the system, the |
|
|
separation ranges from 2 to 22". AB is also known as Rigil Kentaurus. |
|
|
Henroteau notes that a first attempt to measure the relative positions |
HFC1928 |
|
of binary components was made by Father Louis Feuillee in 1709, when |
Feu1714 |
|
he estimated the position angle and distance for alp Cen. |
|
|
Proper motion -3642 +699. The distant companion, Proxima Centauri, |
|
|
distance 9000" was discovered by Innes. It is the flare star V645 Cen, |
I__1905 |
|
(mag. 10.7, 2.2 degrees distant, M5Ve). See Kamper & Wesselink (1978). |

The secular changes of a, i, node, and longitude of periastron have |
|
|
been allowed for; quoted elements are for 2000.0. |
|
|
The semi-major axis has been revised (Heintz 1982). |

Difficult for Hipparcos with secondary (= HIP 71681) at edge of |

Pourbaix gives two combined solutions for this resolved SB2, each |

Powell also measured a more distant component (CPD-60 5485) which is |
Pwl1864 |

obviously non-physical (1860.312, 353.7 deg, 161.5"). |

Ca: Based on spectroscopic orbit of Proxima Cen b by Anglada-Escude et |
|
|
al. (2016 Nature 536, 438), Brown (2017) derives an estimate of 0.25 |
|
|
for the eccentricity of the planetary companion. |
BnR2017 |
| alp Cen |
Beamin et al. (2017) searched for faint co-moving companions to the |
|
|
alpha Cen system, examining CCD tiles covering a ~19 deg^2 area and |
|
|
taken at multiple epochs between 2010.2 and 2015.5. No additional |
|
|
companions were detected down to limiting magnitudes Y=19.3 and J=19. |
