Zur Berechnung der Wärmeleitfähigkeiten in Sternatmosphären

It is pointed out that the currently known methods for the calculation of the thermal conductivity of neutral, partly ionized, or completely ionized gases at high temperatures require a relatively large computational effort, not taking into account the method reported by Spitzer and Haerm (1953) for completely ionized gases. An equation is derived which provides an approach for an approximate calculation involving a smaller amount of computational work.
