| contents | Eclipsing binary stars with Delta Scuti components are exceptional systems for gaining a deeper understanding of stellar systems. WY Leo is one such system, exhibiting Delta Scuti-type oscillations. However, it has not been extensively studied in the literature. WY Leo was observed by Transiting Exoplanet Survey Satellite (TESS), providing two sectors of high-quality photometric data. This study focuses on the photometric analysis of WY Leo. Binary modeling was performed, and the system's fundamental stellar parameters, such as mass and radius, were determined. The pulsational properties of WY Leo were also investigated, revealing that the more luminous star exhibits Delta Scuti type oscillations with a period of 0.052 days. The position of the primary component was examined on the HR diagram, and it was found to lie within the Delta Scuti instability strip. |
