Answer:
Being an extreme blue supergiant with 59 solar masses and a surface temperature of over 42000 kelvins, Naos is actually one of the brightest stars in the Milky Way. It's almost 800 000 times as bright as the Sun, although most of that light is ultraviolet.
Explanation:
Wien's displacement law to find the approximate temperature of a star, in this case the Naos temperature would be 64000K, the real temperature is 42000K
Wien's displacement law states that the product of the maximum wavelength emitted by a black body and its temperature is constant
λ_{max} T = 2,898 10⁻³ [ m K]
A black body is a body that absorbs all the radiation that reaches it, which is why it looks black, the cavity inside the black body must be at a fixed mask and it was there so that a thermal equilibrium is established and the radiation can be emitted by the black hole.
The stars approach a black body in the sense that their mission has a similar maximum to that of the black holes, but the temperature is an effective temperature that does not take into account the different processes within the star.
With this wavelength of the emission maximum, the temperature of the stars is calculated, in this case the star Naos is a whitish-blue star, the surface temperature found in tables is 42000K
if we use Wien's displacement law the emission should be
λ_{max} = 2,898 10-3 / T
λ_{max} = 2,898 10-3 / 42000
λ_{max} = 690 nm
this emission corresponds to the color orange
For a blue emission ranging from 450 nm to 500 nm, the temperature of a black body would be
T = 64000K to 57000 K
therefore using wien's displament law the temperature of the star Naos should be approximately 64000k, the fact that the real temperature is lower is because there are several processes with different temperatures inside the star.
In conclusion, Wien's Displacement Law can be used to find the approximate temperature of a star, in this case the Naos Temperature would be 64000K
