WDS 14396-6050 SCZ 1 Ca,Cb : NOTES

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").
	VLTI Uniform disk diameter of A,B:	LTI2003b
	= 8.314 +/- 0.016, 5.856 +/- 0.027 mas,
	VLTI Limb-darkened diameter of A,B:
	= 8.511 +/- 0.020, 6.001 +/- 0.034 mas,
	R = 1.224 +/- 0.003, 0.863 +/- 0.005 \rsun.
	VLTI Limb-darkened diameter of Proxima (C) 1.044 +/- 0.08 mas,	LTI2003a
	M = 0.123 +/- 0.006 \msun, R = 0.145 +/- 0.011 \rsun,
	T = 3042 +/- 117 K.
	VLTI uniform disk diameter of C: 0.990 +/- 0.050 mas,	LTI2009
	VLTI limb-darkened disk diameter of C: 1.011 +/- 0.052 mas,
	R = 0.141 +/- 0.007 \rsun, Teff = 3098 +/- 56 K,
	M = 0.123 +/- 0.006 \msun.
	Teff-A = 5829 +/- 6, Teff-B = 5189 +/- 18 K.	XXX2018a
	Based on astroseismology, age is 5.9 to 7.3 Gyr.	XXX2021a
	Ma = 1.0788 +/- 0.0029 \msun, Mb = 0.9092 +/- 0.0025 \msun;
	Ra = 1.2175 +/- 0.0055 \rsun, Rb = 0.8591 +/- 0.0036 \rsun.	Ake2021
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
