Do All Stars Have Spectrums? Stellar Metamorphosis
Well, do all stars have spectrums? No. The vast majority of stars in an evolved galaxy like our own do not have spectrums. They stopped shining from their own light billions of years ago. Not only that, but astronomers call them "planets/exoplanets", which just exacerbates the problem.
Gases, liquids and solids do not undergo recombination, they are already at lower enthalpies. This means the older/dead stars do not have spectrums.
