astro- modelling a white dwarf via polytrope
have solved the lane - emden eqn numerically for scaled radius, and the derivative of scaled pressure with respect of scaled radius, are given the eqn of state, n, and mass, how would i go about working out the central density and the radius?
thanks |

Huh? Sorry, but can you restate that a little more clearly? Maybe include the equations you worked with too?

[tex]S_{n} = \sqrt{ \frac{(n+1) k_{B}}{4 \pi G m} \frac{T_{c}}{\rho_{c}} }The central density & temperature are Free Parameters*. * For derivation, see: http://www.physicsforums.com/showthread.php?t=278009 [post #8] |
