I've begun a study of the sun's interior and Emden's equation. Yet nowhere on the web does anyone divulge how to calculate the core radius or the inner core variables. One thing I did was to suppose a homologous polytropic core ( n = 3 ) with:
epsilon = energy generation rate
mean epsilon = L / M
rho = density
mean rho = M / V
so I postulated the homology:
epsilon (center) / epsilon (mean) = rho (center) / rho (mean) = eta
This immediately leads to results that closely match one computer model I found, with
core radius = .2643 R = eta^(-1/3) R,
but my approach seems ad hoc. Any help?
