I just noticed and updated this too! Thanks for confirming it for me.
Looks like it produces a density plot, but I need to vary zc to suit the WD mass.
Also my mass isn't plotting anything.
Homework Statement
We need to write an integrator for the Chandrasekhars Equation (CE) for White Dwarfs (WD) using python3/NumPy/Matplotlib. We then need to compute the structure of a WD made of our varying elements. We also need to compute and plot the mass-radius relation for WD.

1. Question from a textbook.
I have written down the differential equations for part a) and shown part b),
but I am unsure of how to tackle part c).
2. This is the Question from the book

Any advice would be grateful. Thank you
I agree with you dipole, OP i would have understood. Starter made me think my account was low on posts or part of the starting community / members from years ago.
I had only posted in my own threads so always saw it on my avatar.
I have used the PF forums on and off for the past few years. I logged in a little while back and noticed it upgraded.
I also noticed I have a Starter tag across my avatar? What is it?
Also I just upgraded to gold membership to show my support, as the forum has been very helpful through my part...
I added Eq 1 to 2 to remove the hv', and rearranged to have u' in terms of all other parameters, giving 2hv + E(1-u) = E'(1+u'), then subbed E' [where E'=m_0 / sqrt(1-u')] back in, and then have (2hv+E(1-u))/m_0 (set this equal to x) = (1+u') / sqrt(1-u'^(2)), then solved for u' in terms of x...
That is what I first thought.
So solve for u' then sub that back into one of the equations and rearranging should produce the proof. The algebra seems to be tedious, ill keep trying to make it work. Thanks for the help mfb
Now I am more confused :(
I added eq 1 and 2, and got 2hv+E(1-u) = E'(1+u') but solving this for u' seems to get complicated. Is there a simpler way to show this proof?
