O článku:
Our precise UBV photometric light curves of a poorly studied Algol-type eclipsing binary V839 Cep were used to derive relative and absolute parameters of the system. The masses of the components 3.3± 0.2 M☉, 4.4±0.3 M☉, radii 1.9± 0.1 R☉, 2.9±0.1 R☉, effective temperatures 14 150±(300) K, 15 700±(300) K and inclination of the orbit 88.15± 0.02 deg were determined. The Eclipse Time Variation (ETV) diagram revealed the apsidal motion in the system with dωobs/dt = 0.027(9)deg yr-1, U = 13600(4500) years.
