K-band spectroscopy of pre-cataclysmic variables [PDF]

, 2007
Aims. There exists now substantial evidence for abundance anomalies in a number of cataclysmic variables (CVs), indicating that the photosphere of the secondary star incorporates thermonuclear processed material. However, the spectral energy distribution

The BINSYN Program Package [PDF]

Journal of Astronomy and Space Sciences, 2012
The BINSYN program package, recently expanded to calculate synthetic spectra of cataclysmic variables, is being further extended to include synthetic photometry of ordinary binary stars in addition to binary stars with optically thick accretion disks ...

The Magnetospheric Boundary in Cataclysmic Variables

EPJ Web of Conferences, 2014
The magnetic cataclysmic variables (MCVs) present a wealth of observational diagnostics for studying accretion flows interacting with a magnetosphere. Spin-period pulsations from the rotation of the white dwarf are seen in optical light, in the UV and X ...

High-Speed Photo-Polarimetry of Magnetic Cataclysmic Variables

Acta Polytechnica CTU Proceedings, 2015
I review recent highlights of the SAAO High-speed Photo-POlarimeter (HIPPO) on the study of magnetic Cataclysmic Variables. Its high-speed capabilities are demonstrated with example observations made of the intermediate polar NY Lup and the polar ...

Nova-like Cataclysmic Variables in the Infrared [PDF]

, 2014
Novalike cataclysmic variables have persistently high mass transfer rates and prominent steady state accretion disks. We present an analysis of infrared observations of twelve novalikes obtained from the Two Micron All Sky Survey, the Spitzer Space ...

Magnetic cataclysmic variable accretion flows [PDF]

AIP Conference Proceedings, 2007
We have used a magnetic accretion model to investigate the accretion flows of magnetic cataclysmic variables (mCVs) throughout a range of parameter space. The results of our numerical simulations demonstrate that broadly four types of flow are possible: discs, streams, rings and propellers. We show that the equilibrium spin periods in asynchronous mCVs,

Cataclysmic Variables in the SUPERBLINK Proper Motion Survey [PDF]

, 2014
We have discovered a new high proper motion cataclysmic variable (CV) in the SUPERBLINK proper motion survey, which is sensitive to stars with proper motions greater than 40 mas/yr.
