		| Abstract: | 
		This study presents the results of the medium-resolution optical spectra of S Equ obtained with the echelle spectrograph of the Catania Astrophysical Observatory. In this work, new radial velocity curves for the components of the system with a precision better than in previous works are obtained using the cross-correlation technique. We have determined the absolute parameters of S Equ combining the orbit and light curve solutions. The preliminary results of the Hα line analysis indicate an extra emission and absorption as a likely result of a mass-transfer process and chromospheric activity of the cooler component. |
