我们正在更新和扩展OPAL状态方程（EOS）和不透明度数据，以包括低质量恒星。EOS部分的工作现在已经完成，结果在这里描述。新的数据涵盖了质量≥0.1 M的主序星。由于低质量恒星遇到的更极端的物质条件，我们增加了新的物理学。电子现在被当作相对论性的，我们改进了对分子的处理。我们还考虑了日震学的新结果的影响。
We are in the process of updating and extending the OPAL equation-of-state (EOS) and opacity data to include low-mass stars. The EOS part of that effort now is complete, and the results are described herein. The new data cover main-sequence stars having mass ≥0.1 M☉. As a result of the more extreme matter conditions encountered with low-mass stars, we have added new physics. The electrons are now treated as relativistic, and we have improved our treatment of molecules. We also consider the implications of the new results for helioseismology.
