レーン＝エムデン方程式
1. Lane–Emden equationIn astrophysics, the Lane–Emden equation is Poisson's equation for the gravitational potential of a self-gravitating, spherically symmetric polytropic fluid. It is named after the astrophysicists Jonathan Homer Lane and Robert Emden. Its solution provides the run of pressure and density with radius r in terms of a re-scaled radial variable and a re-scaled density variable : where and where the subscripts "c" refer to the values of pressure and density at the center of the sphere.
