Volume

Would this also be the largest star by volume (which seems to be closer to what the image shows anyway)? --Sfnhltb (talk) 14:12, 27 July 2010 (UTC)[reply]

Apparently not, see VY Canis Majoris. — Martin (MSGJ · talk) 14:43, 27 July 2010 (UTC)[reply]

Ultraviolet Star

Its energy temperature (Boltzmann's constant multiplied by its kelvin temperature) is about 4.57 eV, which falls in the near ultraviolet range. So while the star looks blue to the human eye, and is described as blue in the text, it seems like it might be more accurate to refer to it as an ultraviolet star? Stonemason89 (talk) 19:12, 27 July 2010 (UTC)[reply]

It is not described as blue in the text, it is described as a blue hypergiant, which means it should be spectral type-O or type-B and luminosity class-0. "blue hypergiant" is a technical term indicating spectral type and luminosity class. 76.66.193.119 (talk) 07:19, 7 August 2010 (UTC)[reply]

I suppose it would be a good idea to create a section on the radiation profile of the star (what colour it looks like to the naked eye, the power spectrum of its radiation, etc) 76.66.193.119 (talk) 07:22, 7 August 2010 (UTC)[reply]
