Abstract:

Eclipsing binary systems play a pivotal role in quantifying the absolute parameters of stars, such as the mass (M), the radius (R), and the luminosity (L), offering invaluable laboratories for astronomical research and enhancing our comprehension of stellar evolution as well as galaxy dynamics. These systems provide a unique opportunity to precisely ascertain these crucial parameters. The simultaneous analyses of high-quality space observations, combined with ground-based photometric data, have allowed more sensitive detection of fundamental stellar parameters by multicolour photometry. In the paper, the absolute parameters of the component stars for the V1010 Cas binary system were sensitively obtained by a simultaneous analysis of the Transiting Exoplanet Survey Satellite (TESS) light curve, and new CCD observations in BVRI filters obtained with 60 cm Robotic telescope (T60) at the TUBITAK National Observatory. Thereby, the radii and masses of the primary and secondary components were determined as R1 = 2.46  0.01 R, R2 = 1.78  0.03 R, and M1 = 2.06  0.05 M, M2 = 1.83  0.04 M, respectively. The distance of V1010 Cas was also calculated as 444  42 pc. Furthermore, the system's overall age was approximated at about 570 ± 60 Myr.
