# Electron density in the sun

I'm currently working on solar neutrino and in order to make a numerical simulation, I need the potential felt by electron-neutrino : $$V_e(r) = \sqrt{2} G_F N_e(r)$$ where $N_e(r)$ is the electron density perceived by the neutrino and $G_F$ the Fermi coupling constant associated to the weak interaction. Do you know any website able to provide me with data or formulas? (I just know that $N_e$ is roughly exponential).

Thank you!

• You should edit the information about symbols into the body of the question. It's not a good idea to expect people to look for additional info like this in comments. – StephenG Apr 21 '18 at 16:30
• See this question for density of the sun as a function of radius. – Zeick Apr 24 '18 at 11:54
