what is the temperature of vy canis majoris according to a 2006 study which derived a luminosity of 60,000 l☉?
3,650 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.

vy canis majoris (abbreviated to vy cma) is an extreme oxygen-rich (o-rich) red hypergiant (rhg) or red supergiant (rsg) and pulsating variable star located at away from earth in the constellation of canis major. it is one of the largest known stars by radius, and is also one of the most luminous and massive red supergiants, as well as one of the most luminous stars in the milky way.
