1. The problem statement, all variables and given/known data
Let be the density given by the expression p = pc(1-r/R) where R is tha radius of the star. Find the stratification for pressure and temperature.
2. Relevant equations
Equilibrium eq. dP/dr = -Gm(r)p/r2
Continuity eq. dm/dr = 4*Pi*r2p
PS.: p == rho (sorry for not using TeX)
3. The attempt at a solution
The main problem is how to find the temperature stratification... maybe using the ideal gas equation PV =nRT?

Have you already found the pressure distribution? If so, try rewriting the ideal gas law in terms of density, by multiplying both sides of PV=nRT by molar mass.
