| 英文摘要 | We present CCD light curves of V710 Mon obtained in 2007 and 2013. By using the 2010 version of the W-D code, it is found that the star is a deep (59.5-62.7%) contact binary system, with an extreme mass ratio (0.143-0.183). The period of the system increases with a rate dP/dt = +1.95( +/- 0.06) x 10(-7) days/year. We propose that the system contains a post-main-sequence component which may be in an expanding phase. The time scale of the orbital increase nearly equals to the time for the post-main-sequence star to evolve into a subgiant. The age of the primary is estimated to be 5.34 Gyr.
