In this study, the photometric and spectroscopic observational data analysis of the Algol-type binary system GT Eri, selected from the southern hemisphere sky, is presented. The spectroscopic observations of GT Eri were carried out during the 2012–2013 and 2022 observing seasons at the South African Astronomical Observatory (SAAO), using the 1.9 m Cassegrain telescope equipped with SITe and SpUpNIC CCD cameras and a slit (grating) spectrograph. For the photometric analysis of GT Eri, data from the Transiting Exoplanet Survey Satellite (TESS) were used. The spectroscopic data reduction and the determination of the radial velocity curve of the primary component were performed using the packages available within the IRAF software. The photometric analysis of GT Eri was done with the Wilson–Devinney method. By combining the results of the photometric and spectroscopic data analyses, the absolute parameters of the binary system were determined, and its evolutionary status was interpreted.
