标题： Interpretation of the BRITE oscillation data of the hybrid pulsator $ν$ Eridani: a call for the modification of stellar opacities

摘要： 对主序早期B型恒星$\nu$金牛座的BRITE振荡谱的分析结果进行了介绍。 只有采用修改后的平均不透明度分布模型才能解释观测到的频率范围以及某些单独频率的数值。 $\kappa$个修改后的地震模型的数量受到非绝热参数$f$的限制，该参数对在脉动驱动的光球下层中不透明度的变化非常敏感。 我们提供了一个满足上述所有条件的模型示例。 似乎OPLIB不透明度比OPAL和OP项目的结果更受青睐。 此外，我们还讨论了不透明度修改的其他后果，即Z峰区域对流效率的增强，以及出现接近径向模式的现象，这是一种在标准主序模型中的非径向模式中常见的避免交叉现象。 显示英文摘要

摘要： The analysis of the BRITE oscillation spectrum of the main sequence early B-type star $\nu$ Eridani is presented. Only models with the modified mean opacity profile can account for the observed frequency ranges as well as for the values of some individual frequencies. The number of the $\kappa$ modified seismic models is constrained by the nonadiabatic parameter $f$, which is very sensitive to the opacity changes in the subphotospheric layers where the pulsations are driven. We present an example of the model that satisfies all the above conditions. It seems that the OPLIB opacities are preferred over those from the OPAL and OP projects. Moreover, we discuss additional consequences of the opacity modification, namely, an enhancement of the efficiency of convection in the Z-bump as well as an occurrence of close radial modes which is a kind of avoided-crossing phenomenon common for nonradial modes in standard main sequence models.
