“…Besides our observations, two other sets of light curves are analyzed together in this paper. One set directly came from the table in Samec's paper (Samec et al 2008). The data were taken on 2006 May 15-28 in Johnson-Cousins B, V , Rc and Ic filters at Lowell Observatory and Kitt Peak, and are shown in the upper right panel of Figure 1.…”

“…Based on the mass ratio q and the orbital period of 0.446134671 days (Samec et al 2008), the trajectory of the mass flow is calculated under the mass point model 7 . The leaf shaped curves originating from the inner Lagrange point in Figure 5 trace the trajectories.…”

“…Hoffman et al (2006Hoffman et al ( , 2008 grouped it as an Algol/β Lyrae system based on observations from the Northern Sky Variability Survey. Samec et al (2008) published the first high precision multi-color light curves, and listed the observational data in their paper; they deduced that it is a near-contact but detached binary system. Four sets of light curves are analyzed together in this paper.…”

Some properties of mass transfer within a semi-detached binary system are discussed based on an example of VV Vir. The observations and analysis of VV Vir show that it is a semi-detached binary system with the less massive cooler component filling its Roche lobe, which is also called an Algol-type binary system. Based on the parameters of this semi-detached binary, a theoretical study on the mass flow is carried out, including the trajectory of the mass flow, the position, radius and temperature of the impact spot caused by the mass flow, the inconsistent form of the mass flow and the possibly huge rate of energy transfer carried by the mass flow. Humps and distortions in light curves of VV Vir are deemed to be weak evidence for the theoretical results.
