Radiation driven winds of hot luminous stars. III. Detailed statistical equilibrium calculations for hydrogen to zinc.

Multilevel statistical equilibrium calculations for the dominant ions of H to Zn in hot star stellar winds have been performed, comprising 133 ionization stages of 26 elements with a total of 400 levels and 10,000 radiative bound-bound transitions. Non-LTE effects are shown to be significant, and an important back reaction of the improved occupation numbers on the wind dynamics is found. A cool wind model for Zeta Pup can account for high ionization species including O VI, S VI, and N V, while application of the calculations for the case of Tau Sco produces sufficient N V but only marginal O VI. The collision free two-level approximation for particle densities greater than 10 to the 10th/cu cm is found, for excited levels, to be poor.
