The New Eclipsing Cataclysmic Variable SDSS 154453+2553
, 2011 The cataclysmic variable SDSS154453+2553 was recently identified in the Sloan Digital Sky Survey. We obtained spectra and photometry at the MDM Observatory, which revealed an eclipse with a 6.03 hour period.

Tilted Disk Precession and Negative Superhumps in HS 2325+8205: A Multiwindow Analysis
The Astrophysical JournalTilted disk precession exists in different objects. Negative superhumps (NSHs) in cataclysmic variable stars are believed to arise from the interaction between the reverse precession of a tilted disk and the streams from the secondary star.

Pole-On Cataclysmic Variables as Be Stars [PDF]
International Astronomical Union Colloquium, 1987 Cataclysmic-variable stars (CVs) are technically Be stars, since Balmer emission lines appear in their spectra. In general, CV spectra are so unusual that they are easily recognized. The main features are extremely broad, shallow hydrogen lines with broad, faint emission cores.

Idling Magnetic White Dwarf in the Synchronizing Polar BY Cam. The Noah-2 Project
, 2008 Results of a multi-color study of the variability of the magnetic cataclysmic variable BY Cam are presented. The observations were obtained at the Korean 1.8m and Ukrainian 2.6m, 1.2m and 38-cm telescopes in 2003-2005, 56 observational runs cover 189 ...

Orbital variations and outbursts of the unusual variable star V1129 Centauri
, 2017 The variable star V1129 Cen is classified in the GCVS as being of $\beta$ Lyr type. Unusual for such stars, it exhibits outbursts roughly once a year, lasting for $\sim$40 days. For this reason, a relationship to the dwarf novae has been suspected. Here,

The Secondary Stars of Cataclysmic Variables
, 2011 I review what we know about the donor stars in cataclysmic variables (CVs), focusing particularly on the close link between these binary components and the overall secular evolution of CVs. I begin with a brief overview of the "standard model" of CV evolution and explain why the key observables this model is designed to explain - the period gap and the

What’s Cool About Hot Stars? Cataclysmic Variables in the Mid-Infrared [PDF]
, 2009 We review recent results from mid-infrared observations of cataclysmic variables with the Spitzer Space Telescope. In general, these observations have revealed mid-infrared excesses, above the level expected from the stellar and accretion components, in ...

Magnetically warped discs in close binaries
, 2002 We demonstrate that measurable vertical structure can be excited in the accretion disc of a close binary system by a dipolar magnetic field centred on the secondary star.
