Abstract

We present the first CCD observations of an eclipsing binary, ZTFJ015003.88+534,734.1, which is a member in the open star cluster UBC 188. The observations were taken by the 1.88 m telescope at the Kottamia Astronomical Observatory (KAO) in SDSS griz bands. The latest version of the Wilson-Devinney (W-D) code was employed for photometric analysis and light curve modeling of the eclipsing binary. The results indicate that the binary system is in an over-contact configuration. The mass of the primary star (M1) is determined to be 1.293 M_⊙, and the mass of the secondary star (M2) is directly derived from the system's estimated mass ratio (q = M2/M1) as 0.340 times the solar mass (M_⊙). We investigated the color-magnitude diagram and the membership probability of the open cluster UBC 188 using the Gaia DR3 data. We determined the membership probability of the eclipsing binary ZTFJ015003.88+534,734.1 using the pyUPMASK algorithm and found that its membership probability is one.

对新发现的年轻疏散星团 UBC 188 中的成员食双星 ZTFJ015003.88+534,734.1 的首次 CCD 测光研究

我们首次展示了对一个食双星ZTFJ015003.88+534,734.1的CCD观测数据，它是疏散星团UBC 188中的一个成员。这些观测数据是由科塔米亚天文台（KAO）的 1.88 米望远镜在 SDSS griz 波段上拍摄的。采用最新版本的威尔逊-德文尼（W-D）代码对该食双星进行了测光分析和光曲线建模。结果表明，该双星系统处于超接触构型。主星（M1）的质量被确定为 1.293 M⊙，次星（M2）的质量是根据该系统的质量比（q = M2/M1）直接推算出来的，是太阳质量（M⊙）的 0.340 倍。我们利用 Gaia DR3 数据研究了开放星团 UBC 188 的色-星图和成员概率。我们利用 pyUPMASK 算法确定了食双星 ZTFJ015003.88+534,734.1 的成员概率，发现其成员概率为 1。
