  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.
