The mean photon energy for a black body at 1 million K is calculated to be approximately 300 eV. This value is significantly higher than the mean photon energy of solar radiation, which is around 1.74 eV for a temperature of about 5,800 K. Consequently, the peak wavelength of the black body spectrum at 1 million K is much shorter than that of the Sun. The calculations align with expectations for black body radiation. The discussion concludes with the participant feeling satisfied with the information received.

I have calculate that the mean approximate photon energy of a black-body spectrum which is emitted by an object at a temperature of 1 million K is 300eV. Can somebody confirm me that? My second doubt is: the wavelength at which this spectrum reaches a peak corresponds to a "longer" or to a "shorter" wavelength than that of the black-body spectrum emitted by the sun?
Many thanks

What do your calculations show for the Sun?
 
I did not do any calculation about the sun but think that the spectrum of solar radiation is close to that of a black body with a temperature of circa 5,800 K and so the mean approximate photon energy is 1.74eV. If that so, are the wavelength at which this spectrum of the object at at a temperature of 1 million K that reaches a peak corresponds to a much shorter wavelength than that of the black-body spectrum emitted by the sun?
 
300eV-photons have a shorter wavelength than 1.74eV-photons.
The numbers are in a region where I would expect them, but I did not calculate them.
 
Yes, the peak is a much shorter wavelength than the Sun emits. Do you know much about EM radiation and black body radiation?
 
Thanks. yes, now I have all the info I needed.

Such objects are very bright (obiously) and very energetic. The article indicates that AT 2024wpp had a peak luminosity of 2-4 x...
