Abstract: | The blue and yellow light curves of the RS CVn-type eclipsing binary Z Her were analyzed by using Wood's and Nelson. Davis and Etzel's methods. The results obtained by two different approaches are in good agreement. The absolute parameters of the components were also calculated using the parameters derived by Popper from the radial velocities. The physical parameters of the components indicate that the cooler one has separated or has been departing from the Main Sequence. |
