AI 中文摘要
对食双星（EBs）中类太阳振荡红巨星的研究，为结合动力学质量与半径测量及星震约束推进恒星天体物理学提供了独特机会。食双星可提供与距离无关的精确基本参数（如质量、半径、光度），而类太阳振荡可探测恒星内部，用于检验确定恒星质量与半径的星震标度关系。我们采用两种不同方法估算系统初始化学成分：方法I将初始氦丰度（Y₀）作为自由参数，方法II在假设Y₀与Z₀存在关联的前提下，将初始金属丰度（Z₀）作为自由参数。我们为11个食双星的成员星分别构建内部模型，其中8个系统得到同代解。两种方法得到的年龄与化学成分总体一致，研究结果为银盘部分区域的化学演化提供了重要线索。此外，利用两颗振荡星Tek Ayak（KIC 8410637）和KIC 9970396的参数，而非标度关系中的太阳参考值，得到的质量与半径与动力学解的吻合度高得多，且无需额外修正。
英文摘要
The study of solar-like oscillating red giants in eclipsing binaries (EBs) provides a unique opportunity to advance stellar astrophysics by combining dynamical mass and radius measurements with asteroseismic constraints. EBs provide precise fundamental parameters (e.g. mass, radius, and luminosity) independent of distance, while solar-like oscillations probe stellar interiors and enable tests of asteroseismic scaling relations used to determine stellar masses and radii. {We apply two different methods to estimate the initial chemical composition of the systems. In Method I, the initial helium abundance ($Y_0$) is treated as the free parameter, whereas in Method II the free parameter is the initial metallicity ($Z_0$), assuming a relation between $Y_0$ and $Z_0$. We construct interior models individually for the components of 11 EBs and obtain coeval solutions for eight systems.} The ages and chemical compositions derived from the two methods are generally consistent with each other. Our results provide important clues about the chemical evolution of a part of the Galactic disk. Moreover, using the parameters obtained for two oscillating stars, Tek Ayak (KIC 8410637) and KIC 9970396, instead of solar reference values in the scaling relations yields masses and radii that are in much better agreement with the dynamical solutions without requiring additional corrections.
