Description

The table covers densities \rho from 10-6 to 109 g/cc, temperatures T from 103 to 109 K, and ion charge numbers Z from 1 to 60. At given Z, atomic mass of the most abundant isotope was adopted for the calculations.

Caution should be taken since the assumption of full ionization is not valid in some parts of the density-temperature domain. The region of partial ionization has not been excluded from the table for two purposes:

The file "condall06.d" presents a multipart table. Every part corresponds to one specific Z (indicated at the corner of the table). The first (column) entry of every part is decimal logarithm of \rho in g/cc, and the second (row) entry is logarithm of T in K.

The Fortran program supplied here uses Z, T, and density \rho as input parameters and performs quick interpolation in the data file "condall06.d". If compiled "as is," it displays the decimal logarithm of the conductivity (in CGS units) on terminal. However, the first (MAIN) routine can be easily modified to yield another output. Alternatively, the MAIN routine can be commented-out for usage of the principal subroutine CONINTER with another package. Simultaneously, this subroutine provides logarithmic derivatives of the thermal conductivity over density and temperature, which are often needed for stellar modelling. Format of usage in another Fortran subroutine:

call CONINTER(Zion,TLG,RLG,CK,DRK,DTK)
