摘要:

慢脉动B型星HD 182255的地震模拟产生了两个主导模式的径向阶数的强约束。对于这些频率,我们也推导出经验值的复杂的非绝热参数$f$。这两个地震工具,即,脉动频率和相关的$f$值允许测试可用的不透明度数据、化学成分和过冲效率。

英文摘要:

Seismic modeling of the Slowly Pulsating B-type star HD182255 yields strong constraints on the radial orders of the two dominant modes. For these frequencies, we derive also the empirical values of the complex nonadiabatic parameter $f$. These two seismic tools, i.e., pulsational frequencies and the associated values of $f$, allow to test available opacity data, chemical composition and overshooting efficiency.
