Scientific paper

Time-resolved spectroscopy and photometry of two cataclysmic variables are presented. A radial velocity study shows CT Ser (Nova Ser 1948) has an orbital period of 0.195 ± 0.002 days. Its light curve shows only erratic flickering. A radial velocity study shows that V825 Her (PG 1717+413) has an orbital period of 0.206 ± 0.002 days. Time-resolved photometry shows quasi-periodic oscillations (QPOs), with periods between 15-24 minutes.
This poster is based on observations made at Mount Laguna Observatory, which is operated by the Department of Astronomy at San Diego State University, and at MDM Observatory, which is owned and operated by the University of Michigan, Dartmouth College, the Massachusetts Institute of Technology, Columbia University, and the Ohio State University.
