HS2331+3905: The cataclysmic variable that has it all
S. Araujo-Betancor, B. T. Gaensicke, H. -J. Hagen +6
We report detailed follow-up observations of the cataclysmic variable HS2331+3905, identified as an emission-line object in the Hamburg Quasar Survey. An orbital period of 81.08min…
A 150MG magnetic white dwarf in the cataclysmic variable RX J1554.2+2721
B. T. Gaensicke, S. Jordan, K. Beuermann +4
We report the detection of Zeeman-split Lalpha absorption pi and sigma+ lines in the far-ultraviolet Hubble Space Telescope/Space Telescope Imaging Spectrograph spectrum of the mag…
Rapid Oscillations in Cataclysmic Variables. XVI. DW Cancri
Joseph Patterson, John Thorstensen, Tonny Vanmunster +7
We report photometry and spectroscopy of the novalike variable DW Cancri. The spectra show the usual broad H and He emission lines, with an excitation and continuum slope character…
Spectroscopy of Seven Cataclysmic Variables with Periods Above Five Hours
John R. Thorstensen, William H. Fenton, Cynthia J. Taylor
We present spectroscopy of seven cataclysmic variable stars with orbital periods P(orb) greater than 5 hours, all but one of which are known to be dwarf novae. Using radial velocit…
