论文摘要
目前的工作涉及开普勒脱落二元KIC 8504570的紫心理学。特别是，它重点关注该系统的振荡成分的脉动行为及其物理参数的估计，以丰富如此远的此类系统的较差样本。使用光谱观测，确定了主要成分的光谱类型，并用于创建准确的光曲线模型并估算其绝对参数。随后使用傅立叶变换技术分析了光曲线残差以获得脉动模型。使用$δ$ Scuti星的理论模型来识别脉动器的六个独立频率的振荡模式。另外，还检测到385多个组合频率。讨论了该系统的$δ$ SCUTI星的绝对和脉冲特性，并将其与当前已知的所有相似情况进行了比较。此外，使用$δ$ Scuti恒星的最近（经验）亮度 - 脉冲期关系，估计了系统的距离。
The present work concerns the Asteroseismology of the Kepler detached eclipsing binary KIC 8504570. Particularly, it focuses on the pulsational behaviour of the oscillating component of this system and the estimation of its physical parameters in order to enrich the so far poor sample of this kind of systems. Using spectroscopic observations, the spectral type of the primary component was determined and used to create accurate light curves models and estimate its absolute parameters. The light curve residuals were subsequently analysed using Fourier transformation techniques to obtain the pulsation models. Theoretical models of $δ$ Scuti stars were employed to identify the oscillation modes of the six detected independent frequencies of the pulsator. In addition, more than 385 combination frequencies were also detected. The absolute and the pulsational properties of the $δ$ Scuti star of this system are discussed and compared with all the currently known similar cases. Moreover, using a recent (empirical) luminosity-pulsation period relationship for $δ$ Scuti stars, the distance of the system was estimated.
