| Description | The period changes of six eclipsing binaries have been studied with focus on the light time effect. With the least squares method we also calculated parameters of such an effect and properties of the unresolved body in these systems. With these results we discussed the probability of presence of such bodies in the systems with respect to possible confirmation by another method. In two systems we also suggested the hypothesis of fourth body or magnetic activity for explanation of the "second order variability" after subtraction of the light time effect of the third body. |
