Scientific paper

Results of simultaneous spectroscopic and photometric observations of two southern W UMa systems, AE Phe and YY Eri, are described. Photometric observations were performed using a CAT telescope, equipped with a CES spectrograph, a short camera, and CCD, and an ESO 50-cm telescope. The high-precision spectroscopy was based on the Doppler imaging method. It is concluded that both systems show asymmetric perturbations of the light curves. The most evident feature of this effect is that the maximum following primary minimum (max I) is brighter than the maximum II. There was similarity between photometric and spectroscopic maps, especially in reference to the spot location and temperature distribution.
