Description
V2790 Ori is a W Uma Eclipsing Binary with an orbital period of 0.28784200 day. From the previous investigation of its light curve, it was found that this binary system has a continuous orbital period change. A light curve of V2790 Ori was analyzed using program Maxlm DL4 and its period change was also calculated. The result revealed that the orbital period of V2790 Ori was continuously decreased at rate of 3.44623820×10$^{-3}$ seconds per year to 8.67350882×10$^{-3}$ seconds per year. From the analysis of physical parameters and model, it was found that V2790 Ori had a contact characteristic had high mass ratio. This would be the evolution of V2790 Ori would be a single star due to mass transfer of the system.
