what is the temperature of vy canis majoris according to a study which derived a luminosity of 430,000 l☉?
3,650 k
almost immediately another paper published a size estimate of and concluded that vy cma is a true hypergiant. this was based on the most recent temperature calibrations, giving an effective temperature of 3,450–3,535 k, and a luminosity of based on sed integration and a distance of .

vy canis majoris





























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.
