FUSE Spectroscopy of the Transitional Magnetic Cataclysmic Variable V405 Aurigae
David K. Sing, Steve B. Howell, Paula Szkody +1
We present Far Ultraviolet Spectroscopic Explorer observations of the magnetic cataclysmic variable V405 Aurigae. Together with four other DQ Her type binaries, V405 Aur forms a sm…
The Secondary Stars in Short Period (Magnetic) Cataclysmic Variables
Steve B. Howell
We review the recent knowledge base pertaining to causes for mass accretion variations (high/low states) in highly magnetic cataclysmic variables (i.e. polars). We then examine wha…
On the Masses of the Secondary Stars in CVs
S. B. Howell
Recent theoretical efforts have made predictions for the masses of the secondary stars in cataclysmic variables. Accurate observational determinations for M are sparse and typi…
The Faint Sky Variability Survey I: An Overview
P. J. Groot, P. M. Vreeswijk, M. E. Everett +1
The Faint Sky Variability Survey is aimed at finding variable objects in the brightness range between 17th and 25th magnitude on timescales between tens of minutes and years with p…
High spectral and time resolution observations of the eclipsing polar RX J0719.2+6557
G. H. Tovmassian, P. Szkody, J. Greiner +7
We present phase-resolved spectral and multicolor CCD-photometric observations of the eclipsing polar RX J0719.2+6557 obtained with relatively high time (~600 sec/15 sec) and spect…
A New Cataclysmic Variable RX J0757.0+6306: Candidate for the Shortest Period Intermediate Polar
G. H. Tovmassian, J. Greiner, P. Kroll +8
A new cataclysmic variable is identified as the optical counterpart of the faint and hard X-ray source RX J0757.0+6306 discovered during the ROSAT all-sky survey. Strong double-pea…
