# Astrophysics in a Nutshell Problem

• fu11meta1
In summary, the conversation discusses a hypothetical star with constant density and a classical, non-relativistic, ideal gas composition. The task is to determine the temperature profile of the star, with the use of the equation dT(r)/dr = (-3*L(r)*k(r)*ρ(r)) / (4∏*(r^2)*4*a*c*(T(r))^3). The individual discussing the problem attempted to identify which values on the right side of the equation were constant, but was unsure. They request a full explanation of the principles and equations involved in solving the problem.

## Homework Statement

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))

## Homework 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

## 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))
