LIGHT AND FREQUENCY ANALYSIS OF DETACHED ECCENTRIC BINARY SYSTEM DT CAM WITH PRE-MAIN SEQUENCE COMPONENT
(Univ Nacional Autonoma Mexico, Inst De Astronomia, 2024) Ozdemir, Tuncay; Gurol, Birol
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 <^>x0.605 days. The masses and radii of the primary and secondary components were calculated as M1 = 1.793M0, M2 = 1.414M0, R1 = 1.355R0, and R2 = 1.522R0, 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.
