The AM Herculis Magnetic Variables
James Liebert,H. S. Stockman +1 more
TL;DR: The observational properties of the ten known AM Her systems are reviewed in this article, where the important physical processes involved in the accretion flow and funnel shock, with emphasis on the properties of emission line regions, are discussed.

Spitzer space telescope observations of magnetic cataclysmic variables: possibilities for the presence of dust in polars
Carolyn Brinkworth,D. W. Hoard,Stefanie Wachter,Steve B. Howell,David R. Ciardi,Paula Szkody,Thomas E. Harrison,G. van Belle,A. A. Esin +8 more
TL;DR: In this paper, the authors combined the Spitzer IRAC (3.6-8.0 μm) data with the 2MASS JHK_s photometry to construct the SEDs of six short-period polars, EF Eri, V347 Pav, VV Pup, V834 Cen, GG Leo, and MR Ser.
Journal ArticleDOI
A search for brown dwarf like secondaries in cataclysmic variables – II
TL;DR: In this paper, the spectral energy distribution of a sample of short-orbital-period cataclysmic variables that are candidates for harboring substellar companions is used to detect the K I and Na I absorption lines of the companion star in VY Aqr.
Journal ArticleDOI
Stokes imaging, Doppler mapping and Roche tomography of the AM Herculis system V834 Cen
TL;DR: In this article, phase-resolved spectroscopic and polarimetric observations of the polar (AM Herculis star) V834 Cen during a high state of accretion are reported, where strong emission lines and high levels of variable circular and linear polarization are observed over the orbital period.

An absence of x-ray accretion shock instability signatures in tw hydrae
TL;DR: In this paper, the authors find no clear explanation for the absence of X-ray instability signatures, but suggest that existing one-dimensional models are too simple to explain the three-dimensional shock structure, or that preheating and deceleration of the accretion stream by damping of magnetohydrodynamic waves excited either by the shock itself, or more deeply in the stellar envelope, could ameliorate the instability in the likely case of a sub-Alfvenic shock.
