Abstract : Tables of electron conduction opacity are presented which incorporate recent advances in the theory of electron conduction in stellar matter. The following effects are included: (a) electorn-ion and electron-electron collisions; (b) electron-electron, electron-ion, and ion-ion correlations and shielding; (c) correct treatment of the low-temperature low-density regime where Born approximation fails. A calculation of electron thermal conductivity in the ion solid state is presented. Relativistic effects are not included. Tables are presented for hydrogen, helium carbon, red giant core composition, and solar composition over a range of density from (10 to the minus 5.75 power)g/cc to one million g/cc, and a range of temperature from 1000 to 1 billion degrees K. Regions where the theory breaks down are excluded. (Author)
