NML Cygni
The paper 2004ApJ...610..427Z does give an effective radius of, although they give it in cm. This is based on two assumptions: luminosity = and temperature = 2,500 K.  The luminosity is based on a distance of 2 kpc, and is lifted directly from Morris & Jura 1983. This really has to be adjusted for the much more reliable VLBA distance of 1.61 kpc. Using a more modern IR SED fitting in Schuster 2009, the luminosity has to be adjusted to. This is discussed fully in Zhang 2012. The temperature is more difficult. 2,500 K is lifted from an infrared fit by Monnier 1997, while 3,250 K is from spectroscopy by Ridgeway 1986. 2,500 K is considered far too low for any red supergiant by modern standards, but that in itself doesn't mean it is wrong. Zhang shows the implications of both temperatures. So is certainly verifiable from that paper but equally it should be considered to be wrong. A more valid upper limit would be around which I give in the English article. Lithopsian (talk) 14:56, 3 April 2016 (UTC)
