A Semi-relativistic Equation of State for Stellar Interiors
arXiv:astro-ph/9811200 · doi:10.1002/ctpp.2150390126
Abstract
Using the technique of Pade Approximants for the correlation contributions of charged particles we are able to reproduce complex mathematical expressions by simple algebraic formulas. The Pade formulas are analytical expressions, which interpolate between certain density-temperature regions and are characterized by exact asymptotics. We present a semi-relativistic description of the thermodynamics applicable for stellar interiors. Comparisons with equation-of-state data obtained by other calculational schemes are presented.
