Abstract:
The present study is an analysis of V-band CCD observations of new W
UMa contact binary OQ Dra. To carry out the analysis, Primary and
secondary minimum were obtained and new epoch was calculated. The
computed period of system was 0.33967 day. Light curve analysis was
performed using Binary Maker 3 and PHOEBE that uses the latest
Wilson-Devinney code. We obtained photometric mass ratio of
q_ptm_=0.55.
O'Connell effect also was seen in the fitted model. Finally, the
best model was achieved by introducing 2 spots on each component.
Description:
The photometric observations were performed over 5 nights between 21
June 2015 and 14 July 2015 at RIAAM observatory (research institute
for astronomy and astrophysics of maragha).
