What is the generally accepted temperature of vy canis majoris?
3,490±90 K
In contrast to prevailing opinion, a 2006 study, ignoring the effects of the circumstellar envelope in the observed flux of the star, derived a luminosity of , suggesting an initial mass of and radius of based on an assumed effective temperature of 3,650 K and distance of . On this basis they considered VY CMa and another notable extreme cool hypergiant star, NML Cygni, as normal early-type red supergiants. They assert that earlier very high luminosities of and very large radii of (or even ) were based on effective temperatures below 3,000 K that were unreasonably low.
