Determining Degenerate Gas in Stellar Structure

[Haynes Kwon]

When modeling stellar structure and formulating equation of states, I've seen various cases where you have to take into account whether the constituent gas of a star is degenerate or not. But how do you determine if the gas is degenerate or not?

Simplest check is whenever "electron degeneracy pressure" at zero temperature is exceeded or not. It depends only on electrons concentration.
