The first CCD photometric studies of the member eclipsing binary ZTFJ015003.88+534,734.1 in the newly discovered young open cluster UBC 188
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.
