Summary

Abstract

Transport processes in dense stellar plasmas which are relevant to the interiors of white dwarfs and neutron stars are reviewed. The emphasis is placed on the accuracy of the numerical results. In this review we report on the electrical conductivity and the thermal conductivity of dense matter. The methods of the calculations are different for the liquid metal phase and the crystalline lattice phase. We will broadly review the current status of the calculations of the transport properties of dense matter, and try to give the best instructions available at the present time to the readers.

Nous présentons une revue des propoiétés de transport dans les plasmas denses stellaires caractéristiques des intérieurs de naines blanches et d'étoiles à neutrons. L'accent est mis sur la précision des résultats numériques. Nous présentons la conductivité electrique et la conductivité thermique dans la matière dense. Les méthodes de calcul sont différentes dans la phase liquide et dans la phase cristalline. Nous donnons une revue générale des calculs des propriétés de transport dans la matière dense, et nous essayons de donner les meilleures instructions quant aux données disponibles actuellement.

Introduction

In recent years white dwarf asteroseismology opened up a new fertile land of astrophysics (Bradley & Winget 1991; Bradley, Winget, & Wood 1992). Consequently, the basic physics data which go into white dwarf models need to be sufficiently accurate that they should live up to the standard required by the asteroseismological data.
