# Electron degeneracy in white dwarfs

Consider a plasma in a star. Now in a plasma electrons are so excited that they can no longer be held by the electromagnetic field of the nucleus. But then when we are talking about cores or red giants or white dwarfs themselves they have the electron degeneracy pressure which is due to the potential well caused by the electromagnetic field itself. Does that mean that those electrons once again come under the influence of the electromagnetic force? But doesn't that go against the definition of a plasma?

• The density of quantum states in a spin 1/2 fermion gas is $8\pi p^2/h^3\ dp$, where $p$ is the particle momentum. Ultimately, the particles are confined by gravity in this case. Mar 25 '20 at 8:43
