Polytrope

In astrophysics, a polytrope is a thermodynamic system with pressure dependent upon density, leaving only one independent state variable. A polytropic process is intermediate between an isothermal process and adiabatic one.: 3 The dependence of pressure on density is a solution to the Lane–Emden equation: P = K ρ ( n + 1 ) / n = K ρ 1 + 1 / n…
