First detection of Zeeman absorption lines in the polar VV Pup
E. Mason, D. Wickramasinghe, S. B. Howell +1
We investigated the low state of the polar VV Pup by collecting high S/N time series spectra. We monitored VV Pup with VLT+FORS1 and analyzed the evolution of its spectroscopic fea…
Spectroscopic Observations of Twenty-one Faint Cataclysmic Variables Candidates
E. Mason, S. B. Howell
We provide the first minimum light spectroscopic observations for 21 previously known or suspected faint cataclysmic variable candidates. The sources were selected from the Downes…
Discovery of Two New Faint Cataclysmic Variables
S. B. Howell, E. Mason, M. Huber +1
We report on the discovery of two new faint cataclysmic variables. The objects were selected as candidates from two different imaging surveys aimed at the discovery of such faint s…
Time-resolved, multi-color photometry and spectroscopy of Virgo 4 (OU Vir): a high orbital inclination, short orbital period dwarf nova
E. Mason, S. B. Howell, P. Szkody +3
We present multi-color photometry and time resolved spectroscopy of OU Vir. The analysis of the quiescent light curve shows that OU Vir is characterized by i) strong cycle-to-cycle…
