Abstract

Doppler images are presented for the RSCVn-type binary ζ And. Our upgraded Doppler imaging code TempMap takes into account the distorted geometry of the primary giant component. On the maps several low latitude spots are restored with a temperature contrast of about 1000 K. Some weak polar features are also found. Crosscorrelation of the consecutive Doppler-maps suggests solar-like differential surface rotation.
