Observations of V592 Cas - An Outflow at Optical Wavelengths
S. Kafka, D. W. Hoard, R. K. Honeycutt +1
We present new red optical spectra of V592 Cas aimed at exploring the properties of the outflow of this system in a spectral region where the underlying white dwarf and the accreti…
New Complexities in the Low-State line profiles of AM Herculis
S. Kafka, T. Ribeiro, R. Baptista +2
When accretion temporarily ceases in the polar AM Her, the emission line profiles are known to develop several distinct components, whose origin remains poorly understood. The new…
Cyclotron Modeling Phase-Resolved Infrared Spectroscopy of Polars III: AM Herculis and ST Leo Minoris
Ryan K. Campbell, Thomas E. Harrison, Stella Kafka
We present phase-resolved low resolution infrared spectra of AM Her and ST LMi, two low-field polars that we observed with SPEX on the IRTF. Optical/NIR lightcurves are also publis…
"Dark Matter" in Accretion Disks
Steve B. Howell, D. W. Hoard, C. Brinkworth +3
Using Spitzer Space Telescope photometric observations of the eclipsing, interacting binary WZ Sge, we have discovered that the accretion disk is far more complex than previously b…
QU Carinae: a SNeIa progenitor?
S. Kafka, R. Anderson, R. K. Honeycutt
Optical spectra obtained in 2006-07 of the nova-like cataclysmic variable QU Car are studied for radial velocities, line profiles, and line identifications. We are not able to conf…
