摘要：

A method is presented to include irradiation effects in the modeling of over-contact binaries. The Roche potential is numerically modified in a way to account for mechanical effects of the mutual irradiation of the two binary components. The efficiency of radiative interaction is parametrized by means of the fraction of radiative over gravitational forces for each component of the binary. The modified Roche geometry is implemented as binary model in an eclipse light curve solution code, which is based on the general Wilson-Devinney scheme. As an example the method is applied to the early-type over-contact system V606 Cen.
