Abstract:
We present the photometric analysis of the detached eclipsing binary
V2480 Cyg. After taking the photometric data, the light curve was
analyzed in PHOEBE software, which uses the Wilson-Devinney code.
Due to the observed O'Connell (1951PRCO....2...85O 1951PRCO....2...85O) effect in light
curve, we introduce a spotted model with 3 spots on the components,
and the exact parameters of the system have been achieved. The main
parameters of the system were calculated as about qptm=1.7,
Teff1=8075K and Teff2=3829K.
Description:
To determine the physical parameters of the V2480 Cyg system we have
taken about 3000 images in V and R band Johnson filters over 7 nights
in June and July 2016. We used the 12 inch MeadeLX200 telescope of the
RIAAM Observatory (Research Institute for Astronomy and Astrophysics
of Maragha). The telescope was controlled remotely with StarryNight
software. A QHY6 monochrome CCD were used, which has a quantum
efficiency of about 65% at 550nm.
