With Sanjay Reddy, also of T-16, I presented a paper with this title at the
January 2003 Meeting of the Association of American Physics Teachers (Austin
Texas). The PowerPoint presentation (in zipped
format, PowerPoint 95, 78 KB) is available for you to read now. We submitted
a paper with this title to the American Journal of Physics, and it was published
in Vol. **72**, 892-905 (2004).

The originally submitted version is available for download from http://www.arXiv.org/abs/nucl-th/0309041.

Here are the associated Mathematica and MathCad files that go with that talk and paper.

MathCad is a Windows application. The following Zip archive (27 KB) contains three files,

NewtonianStar, case of polytropic power = 5/3.

FermiGasEoS, for a charge-neutral mixture of neutrons, protons, and electrons in weak interaction equilibrium.

PureNeutronStar, for the Fermi Gas EoS giving energy density as a fitted function of pressure.These should work with the Standard version of MathCad, Version 7, and higher.

These should work with Mathematica, Version 4, and higher, independent of platform. (Windows, Mac, Linux, Sun, and other versions of Mathematica that may exist). Clicking on these links gives you the notebook in ASCII format, which can be copied onto your hard drive and then opened in Mathematica.

All of the above Mathematica files can also be downloaded in a gzipped tar file (184 KB).WhiteDwarf53.nb, Newtonian white dwarf (least massive cases) with polytropic power = 5/3, (53 KB).
