Optical Photometry of the Dwarf Nova QZ Serpentis in Outburst.

KAHLE F.A.

Abstract (from CDS):

We present white-light and two-colour photometry of the dwarf nova QZ Serpentis during the 2020 March outburst and performed differential photometry in the filters Clear (white-light), Johnson-Cousins V and Johnson-Cousins R with respect to the comparison star USNOB1.0 1112-0250654. All observations were obtained in Hilden (Germany). A radial velocity study by Thorstensen et al. (2017) shows this system has an orbital period of 119.75 minutes. After removing linear trends in our data we estimate a superhump period of Psh = 0.0855537 ± 0.0000421 days and a mass ratio of q = 0.133 ± 0.012.
