Can an object emit all the frequencies in the electromagnetic spectrum if we keep increasing its temperature? Please note that I do not mean a blackbody here, but a body which is not at thermal equilibrium.

Answer 1

From what i have studied, no. One of the ways that we know what other planets has on the atmosphere is by the emission of certain wavelenghts of light. Each element has its own signature. Each element has a limit, as Planck has postulated and it will dissipate energy in other forms, like radiation, the hotter it gets.
