Both surfaces appear to be metallic; what, then, is the cause of the observed difference in their radiative power?
Equally important is the inquiry into the mechanism of radiative equilibrium in sun and stars.
It may be connected with the radiative intensity of the star, or its age, or both.
For more complex molecules the radiative and absorptive powers are known to be much greater.
Its evolution is not in one continuous line, but is radiative from one common centre, and is dispersive.
Determining, moreover, the absorptive power of those powders, it is found to go hand-in-hand with their radiative power.
