论文摘要
我们提供了四个黯然失色二进制系统的主要成分的脉动的第一个证据。分析目标的苔丝光曲线，得出光和绝对参数。将傅立叶分析应用于从二进制模型中减去的残差数据，以揭示初选的脉动特征。将系统的组成部分与相同形态类型的众所周知的二元系统进行比较。还讨论了初选的脉动类别的类型。结果表明，CPD-30 740和V1637 ORI正在振荡Eclips Algol型二进制恒星，而HD 97329和TYC 683-640-1被发现是具有脉动脉动主要成分的分离系统。我们得出的结论是，系统的主要成分是脉动恒星。
We present the first evidence for the pulsations of primary components of four eclipsing binary systems. The TESS light curves of the targets are analyzed, the light and the absolute parameters are derived. Fourier analyses are applied to the residual data subtracted from the binary models to reveal the pulsational characteristics of the primaries. The components of the systems are compared to well-known binary systems of the same morphological type. The types of pulsational classes for the primaries are also discussed. Results show that CPD-30 740 and V1637 Ori are oscillating eclipsing Algol type binary stars, while HD 97329 and TYC 683-640-1 are found to be detached systems with pulsating primary components. We conclude that the primary components of the systems are pulsating stars.
