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 = 1.793M⊙,
M2 = 1.414M⊙, R1 = 1.355R⊙, and R2 = 1.522R⊙, 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.
