标题： Testing stellar opacities using asteroseismology

摘要： 我们提出从BA型主序星的恒星脉动分析中可以得出的关于不透明度的约束条件。 此分析包括构建复杂的地震模型，这些模型能够再现观测到的频率以及从多色光度变化中提取的总辐射通量振幅。 恒星地震学，即{\it 星震学}，是天体物理学的一个相对较新的分支，并且目前为内部结构和演化的理论提供了最准确的检验。 我们表明，在温度为$T=110~000-290~000$K的深度，恒星条件下的不透明度需要进行修改。 不透明度数据的修订非常重要，因为它们对天体物理学的所有分支都至关重要。 显示英文摘要

摘要： We present what constraints on opacities can be derived from the analysis of stellar pulsations of BA-type main-sequence stars. This analysis consists of the construction of complex seismic models which reproduce the observed frequencies as well as the bolometric flux amplitude extracted from the multi-colour photometric variations. Stellar seismology, i.e., {\it asteroseismology}, is a relatively young branch of astrophysics and, currently, provides the most accurate test of the theory of internal structure and evolution. We show that opacities under stellar conditions need to be modified at the depth of temperatures $T=110~000-290~000$\,K. The revision of opacity data is of great importance because they are crucial for all branches of astrophysics.
