Quantum mechanics - electrons?
I'm looking for some websites where it tells about how light from warmth from the stars comes from the vibrations of the electrons. Contra the electrons transitions.
I'm actually now sure myself what it is I'm looking for. My teacher told me to write about it in my paper.
It's something about how the light is emitted from stars when the electrons are vibrating and not because of the well-known model where the electrons jump from one shell to another..

Look up the quantum electrodynamics (QED) model. You'll get lots of hits...way over 300,000 with something about the model in them.
QED describes how photons are emitted when the momenta (speed and/or direction) of electrons change. As you might expect, the momenta of electrons in the plasma of hot, high pressure stars are changing quite a bit. Which means lots of photons are emitted.
QED applies to all electrons; both free of and bound to atoms. All that is necessary for photons is that change in momentum. I'm not clear why you'd want to discount the bound electrons as there are lots of elements (i.e., atoms) inside stars and their electrons would be jumping about (changing momenta) from shell to shell emitting photons as well as the free ones.
