Using the technique of Padé Approximants for the correlation contributions of charged particles we are able to reproduce complex mathematical expressions by simple algebraic formulas. The Padé 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.
