Abstract
In this study we analyzed TESS data of detached eccentric binary system DT Cam and we obtained the first physical parameters of the components. We found that the out-of-eclipse variation of the system shows a small amplitude periodic feature. Most of the frequencies obtained are related with the orbital variation except one, for which the period was determined as ≈0.605 days. The masses and radii of the primary and secondary components were calculated as M1 = 1.793Mȯ, M2 = 1.414Mȯ, R1 = 1.355Rȯ, and R2 = 1.522Rȯ, respectively. Considering the physical properties of the primary component we concluded that it is a rotational variable. We found that the massive component is smaller than the low-mass component. It seems that the secondary component is a pre-main sequence star, which is important for the understanding of stellar structure and evolution.
