Photometric Analysis of the Eclipsing Binaries with Eccentric Orbits GSC 4277 0586=V0898 Cep and GSC 4481 0230=V0922 Cep

In 2010-2011 high precision CCD observations were made of the new eclipsing variables GSC 4277 0586 and GSC 4481 0230 and their light curves were analyzed. The photometric elements were calculated. A comparison of the longitude angles in different epochs showed that the line of apsides of the GSC 4277 0586 system may have a negative rotation of ${\overset{.}{\upomega}}_{obs}$ = −0.8 ± 0.5^o /year. This result is based on a small difference between the epochs of the observations, so it is preliminary. The motion of the orbit is quite fast, so that, in order to verify this result, it is sufficient to obtain new light curves and calculate a new value for the longitude of the periastron. An analysis of the light curve for the binary system GSC 4481 0230 showed that the longitude of the periastron of its orbit is very close to 360°. The expected theoretical value for this system is ${\overset{.}{\upomega}}_{th}$ ≤ 0.2^o /year. A reliable determination of the orbital rotation speed of this star will require an interval of at least a few decades between observations.
