For the V band data from ASAS, period analysis using PerSea and light curve analysis using PHOEBE (0.31aV) was performed.  From the period analysis, the accurate periods were determined and found to be lying in a range of 0.28 to 0.96 day. The basic parameters like mass ratio, inclination, temperature, critical potential and fill out factor were derived through light curve analysis. It is observed that few of the binaries display totality and O’Connell effect showing high activity on those binaries. The absolute parameters are derived and their properties are discussed in comparison to a large database of well studied contact binaries. This work gives preliminary photometric solutions for the binaries in study which will further be analyzed and validated using Wilson-Devinney (WD) method. |
