Select "u(z), du/dz from the "Graph" menu:

Select "T0(n), rho0(n), P0(n)" from the "Graph" menu:

Select Table: "T0(n,M)":

There are analytical solutions
of the Lane-Emden differential equation for:n = 0: z0 = sqrt(6) = 2.449490 |

Test of the accuracy of my applet:

The relative error Δz0/z0 is of the same order of magnitude as the step size dz.
