Homework Help: Astrophysics in a Nutshell Problem

  1. Mar 3, 2014 #1
    1. The problem statement, all variables and given/known data

    Consider a hypothetical star of radius R, with density ρ that is constant, i.e. independent of radius. The star is composed of a classical, non relativistic, ideal gas of fully ionized hydrogen,
    Find the the temperature profile (T(r))

    2. Relevant equations
    dT(r)/dr = ( (-3*L(r)*k(r)*ρ(r)) / (4∏*(r^2)*4*a*c*(T(r))^3)
    so sorry this is written poorly

    3. The attempt at a solution
    So what I did is try and assume which of the values on the right side are constant so I could take them outside of the integral, but I'm not sure.

    Please explain principles and equations fully. I really want to understand this!

    Maybe you could state the problem?

    Oh sorry. I thought I did!
    I edited it. I says find the temperature profile (T(r))
