Curious Variables Experiment (CURVE) CCD photometry of QW Serpentis in superoutburst and quiescence

Abstract

We report extensive photometry of the dwarf nova QW Ser throughout its February 2003 superoutburst untill quiescence. During the superoutburst the star displayed clear superhumps with a mean period of days. In the quiescence we observed a double humped wave characterized by a period of days. As both periods obey the Stolz-Schoembs relation with a period excess equal to %, the latter period is interpreted as the orbital period of the binary system
