Is there a simple-model equation for the radial density of a neutron star, from core to shell? I assume there have been models of fermionic gases, anyone have something onhand Is it a specific distribution? Linear? 1/r^2? I know its just a balancing of gravitational potential with strong interaction in the simplest of cases, which would lead to what? Nuclear density orders, with some radial distribution from core to shell? On a similar note, what about for any normal star, such as our sun? (Not interested in numbers but mass distributions) Thanks!
