标题： Empirical Relations for the Sensitivities of Solar-like Oscillations to Magnetic Perturbations

摘要： 恒星的振荡模式频率通常被视为特定恒星模型中的静态量。然而，在现实中，它们可能会受到随时间变化的源（如磁场和流动）的扰动。我们计算了一组质量在 0.7 到 3.0 M$_{\odot}$之间的模型从主序到早期渐近巨星分支的径向 p 模式振荡的灵敏度。我们将这些模式灵敏度与六个演化阶段的基本恒星参数的多项式拟合。我们发现，最佳拟合关系不同于文献中提出的那些，并且在恒星演化的不同阶段会发生变化。结合扰动强度的测量值（例如磁活动水平），所提出的关系可用于评估恒星观测到的振荡频率是否接近未受扰动的基本状态，或者是否需要调整。 显示英文摘要

摘要： Oscillation mode frequencies of stars are typically treated as static for a given stellar model. However, in reality they can be perturbed by time varying sources such as magnetic fields and flows. We calculate the sensitivities of radial p-mode oscillations of a set of models for masses between 0.7-3.0 M$_{\odot}$ from the main sequence to the early asymptotic giant branch. We fit these mode sensitivities with polynomials in fundamental stellar parameters for six stages of stellar evolution. We find that the best-fitting relations differ from those proposed in the literature and change between stages of stellar evolution. Together with a measure of the strength of the perturbation, e.g., of the level of magnetic activity, the presented relations can be used for assessing whether a star's observed oscillation frequencies are likely to be close to the unperturbed ground state or whether they should be adjusted.
