| contents | The observations of eclipsing binary systems are of great importance in astrophysics, as they allow direct measurements of fundamental stellar parameters. By analysing high-quality space-based observations with ground-based photometric data, it becomes possible to detect these fundamental parameters with greater precision using multicolour photometry. Here, we report the first photometric analysis results of the V517 Cam eclipsing binary system by combining the Transiting Exoplanet Survey Satellite (TESS) light curve and new CCD observations in BVRI filters, obtained with a 60 cm robotic telescope (T60) at the TÜBİTAK National Observatory. By means of photometric analyses, the masses and radii of the primary and secondary stars were carefully determined to be $M_{1}= 1.47\pm 0.06\,M_\odot$, $M_{2}= 0.79\pm0.05\,M_\odot$, and $R_{1}=1.43\pm 0.03\,R_\odot$, $R_{2}= 0.75\pm 0.04\,R_\odot$, respectively. Furthermore, the distance to V517 Cam was calculated to be $284\pm20$ pc. The overall age of the system is estimated to be around $63\pm15$ Myr. At this age, the primary component stands near the onset of its main-sequence evolution, near the ZAMS, whereas the secondary component remains in the pre-main-sequence evolutionary phase. To better understand the evolutionary status and nature of V517 Cam, the mass ratio and temperature values, obtained with relatively low sensitivity by photometric measurements, need to be confirmed by spectral analysis. |
