Three stars A, B, C have surface temperatures T _ A , T _ B , T _ C...

Stars approximate black body radiators and their visible colour depend upon the temperature of the radiator. The curves show blue, white, and red stars. The white star is adjusted to $5270K$ so that the peak of its blackbody curve is at the peak wavelength of the sun, $550nm$. From the wavelength at the peak, the temperature can be deduced from the Wien displacement law.
