SUMMARY
The discussion focuses on deriving the pressure and temperature stratification in a star, using the density equation p = pc(1 - r/R). The equilibrium equation dP/dr = -Gm(r)p/r² and the continuity equation dm/dr = 4πr²p are utilized to find the pressure distribution P(r). The ideal gas law, rewritten in terms of density, is suggested as a method to establish a relationship between temperature and pressure. The participants confirm the successful derivation of P(r) and explore the implications for temperature stratification.
