| Sumario: | Eclipsing binary systems play a vital role in astrophysics, as they provide a direct means of measuring fundamental stellar parameters. By combining high-precision space-based observations with ground-based multicolor photometric data, these parameters can be determined with greater accuracy. In this study, we present the first photometric analysis of the IY Aur eclipsing binary system, using a combination of the Transiting Exoplanet Survey Satellite (TESS) light curve and new UBVRI CCD observations obtained with the 60 cm robotic telescope (T60) at the TÜBİTAKNational Observatory. Through detailed photometric modeling, the masses and radii of the system’s primary and secondary components were determined as 1 = 6.51±0.81 ⊙, 2 = 5.39±0.87 ⊙, and 1 = 4.15 ± 0.20 ⊙, 2 = 6.88 ± 0.33 ⊙, respectively. The logarithmic values of luminosity and surface gravity were calculated as log 1=3.14 ± 0.20 ⊙ and log 1=4.01 ± 0.02 cgs for the primary component, and log 2=2.50 ± 0.22 ⊙ and log 2=3.49 ± 0.03 cgs for the secondary component. Furthermore, the distance to IY Aur was estimated as = 1690 ± 237 pc. |
