Photometric Investigation of WY Leo: An Eclipsing Binary System with $\delta$ Scuti Component

Abstract

Eclipsing binary stars with $\delta$ components are exceptional systems for gaining a deeper understanding of stellar systems. WY Leo is one such system exhibiting $\delta$-type oscillations. However, it has not been extensively studied in the literature. WY Leo was observed by the Transiting Exoplanet Survey Satellite (TESS), providing two sectors of high-quality photometric data. This study focused 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 $\delta$-type oscillations with a period of 0.052 days. The position of the primary component was examined on the HR diagram and found to lie within the $\delta$ instability strip.
