Lane-Emden Equation

  1. Sep 28, 2015 #1
    1. The problem statement, all variables and given/known data
    For n=0, compute the expressions forρ(r),T(r),p(r) in terms of the total mass M and radius R of the star.What is the the scale length a in terms of the radius R in this case?

    3. The attempt at a solution
    I'm just starting to learn this equation so just know that n=0, ρ(r)=ρc is the solution for a constant density in compressible sphere.

    Thank you for your help!
