discov_num notes refcode
RHD 1 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). Kpr1978
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). Hei1982a
Difficult for Hipparcos with secondary (= HIP 71681) at edge of Sod1999
the sensitivity profile. Present parallax preferable to HIP value.
Mass-ratio from Kamper & Wesselink.
Pourbaix gives two combined solutions for this resolved SB2, each Pbx2000b
yielding orbital parallaxes and component masses. Pbx2002
AB: Additional notes may be found in van den Bos (1931). B__1931b
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 1.98 +/- 0.03, 2.04, and 1.79 Msun, respectively. Mlk2012
Powell also measured a more distant component (CPD-60 5485) which is Pwl1864
obviously non-physical (1860.312, 353.7 deg, 161.5").

Teff-A = 5829 +/- 6, Teff-B = 5189 +/- 18 K. XXX2018a

LDS 494 AC: alp Cen + Proxima Cen
The Kervella et al. (2017) orbit is based on the following adopted
physical parameters:
alp Cen A: M = 1.1055 +/- 0.0039 Msun R = 1.2234 +/- 0.0053 Rsun
alp Cen B: 0.9373 0.0033 0.8632 0.0037
Proxima : 0.1221 0.0022 0.1542 0.0045 Kev2017
SCZ 1 Ca,Cb: Proxima Centauri. Not a binary! Tok2014d
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. VVV2017b
