Abstract:
We present multicolor photometry of the massive interacting close
binary system V729 Cyg. The light variations of V729 Cyg were observed
in the Bessel U, B, V, R and I bands over 65 nights between August
2010 and October 2011.
Description:
The observations were carried out at the TUB TAK National
Observatory (TUG) with the 60cm telescope.
