论文摘要
我们提供了新的光度和光谱观察结果，并分析了黯然失色的二进制系统V1241 TAU和GQ DRA。我们的光度光和径向速度曲线分析与苔丝光曲线相结合，表明这两者都是常规的半独立二元系统。它们的绝对参数也会得出。我们介绍了系统的$ O-C $分析，并提出了最可能的轨道时期调节机制。此外，将傅立叶分析应用于系统的光度残差数据，以检查组件的脉动行为。我们得出的结论是，系统GQ DRA的主要组件是$δ$ SCT型脉动器，其主要脉动频率为18.58 d $^{ - 1} $，基于我们的$ b $ filter filter Ristual Lightual Light Light Light Light曲线，这是由30分钟的cadence tess Data证明其合理的。尚无对V1241 TAU的脉动行为的令人满意的证据。最后，计算了两个系统组件的进化轨道，而将其在进化图中的位置与其他Algol型系统进行了比较。
We present new photometric and spectroscopic observations and analyses for the eclipsing binary systems V1241 Tau and GQ Dra. Our photometric light and radial velocity curves analyses combining with the TESS light curves show that both are conventional semi-detached binary systems. Their absolute parameters are also derived. We present the $O-C$ analyses of the systems and we propose the most possible orbital period modulating mechanisms. Furthermore, Fourier analyses are applied to the photometric residual data of the systems to check for the pulsational behavior of the components. We conclude that the primary component of the system GQ Dra is a $δ$ Sct type pulsator with a dominant pulsation frequency of 18.58 d$^{-1}$ based on our $B$ filter residual light curve although it can not be justified by 30-minute cadence TESS data. No satisfactory evidence of pulsational behaviour for V1241 Tau was verified. Finally, the evolutionary tracks of the components of both systems are calculated, while their locations within evolutionary diagrams are compared with other Algol-type systems.
