摘要

摘要分析了2012年、2013年和2021年获得的V1059 Cep食双星的三条光变曲线。我们发现这个系统以每年\(d\omega {\text{/}dt = 7.2^\circ \)的速率快速发生着潮汐运动。假定观测到的空速运动速率和理论上的空速运动速率相等，我们根据文献中的温度数据估算了各组成部分的物理特征。根据我们的计算，这两个成分是两颗非常相似的恒星，属于B7V-B7.5V光谱型，质量（\about {\kern 1pt} (3.4\pm 0.3){\kern 1pt} {{M}_{ \odot }}），年龄（180 \pm 30\ ）百万年。

Rotation of the Apsidal Line in the Eclipsing System V1059 Cep

Three light curves of the V1059 Cep eclipsing binary obtained in 2012, 2013, and 2021 were analyzed. We found the rapid apsidal motion in this system at the rate \(d\omega {\text{/}}dt = 7.2^\circ \) per year. Assuming the equality of observed and theoretical apsidal motion rates we estimated physical characteristics of the components based on the data on their temperatures from the literature. According to our calculations the components are two very similar stars of the B7V–B7.5V spectral type with masses \( \approx {\kern 1pt} (3.4 \pm 0.3){\kern 1pt} {{M}_{ \odot }}\) and age \(180 \pm 30\) million years.
