关于内壳跃迁在透明度计算中的重要性
摘要
For high temperatures and densities, stellar opacities obtained from the Opacity Project (OP) were smaller than those obtained from the OPAL project. Iglesias and Rogers [Ap.J. v443, 469 (1995)] suggested that the discrepancy was due to the omission by OP of important atomic inner-shell processes, and considered in detail results for a mixture of 6 elements: H, He, C, O, S and Fe. Extensive new inner-shell data have now been computed using the code AUTOSTRUCTURE. It is shown that the inclusion of these data in the OP work gives opacities for the 6-element mix which are in much closer agreement with those from OPAL. We also discuss a number of problems relating to the calculation of opacities and of equations-of-state in dense plasmas.
