Long‐term optical and near‐infrared photometric and blue spectroscopic observations were obtained for QS Telescopii, V834 Centauri, and BL Hydri. The optical light curves of all three polars displayed large magnitude changes during our observations. These same high‐state and low‐state transitions were also apparent in near‐infrared JHK photometry, although with decreased amplitude. The color of the polar with respect to its state was examined and found not to be a good indicator of the… 

A spectroscopic, photometric, polarimetric, and radio study of the eclipsing polar UZ Fornacis: the first simultaneous SALT and MeerKAT observations

We present phase-resolved spectroscopy, photometry, and circular spectropolarimetry of the eclipsing polar UZ Fornacis. Doppler tomography of the strongest emission lines using the inside-out

XMM-Newton observations of the X-ray soft polar QS Telescopii

Context. On the basis of XMM-Newton observations, we investigate the energy balance of selected magnetic cataclysmic variables, which have shown an extreme soft-to-hard X-ray flux ratio in the ROSAT

Spitzer Space Telescope Observations of Magnetic Cataclysmic Variables: Possibilities for the Presence of Dust in Polars

We present Spitzer photometry of six short-period polars, EF Eri, V347 Pav, VV Pup, V834 Cen, GG Leo, and MR Ser. We have combined the Spitzer IRAC (3.6-8.0 μm) data with the 2MASS JHKs photometry to


We present the first phase-resolved ultraviolet spectroscopy of two polar systems, BL Hyi and EF Eri, in high and intermediate states from the International Ultraviolet Explorer (IUE) during the

Mass Determination and Detection of the Onset of Chromospheric Activity for the Substellar Object in EF Eridani

EF Eri is a magnetic cataclysmic variable that has been in a low accretion state for the past 9 yr. Low-state optical spectra reveal the underlying Zeeman-split white dwarf absorption lines. These

The magnetic cataclysmic variable LSQ1725-64

We present new photometry and spectroscopy of the 94m eclipsing binary LSQ1725-64 that provide insight into the fundamental parameters and evolutionary state of this system. We confirm that

Phase-resolved X-ray spectroscopy and spectral energy distribution of the X-ray soft polar RS Caeli

RS Cae is the third target in our series of XMM-Newton observations of soft X-ray-dominated polars. Our observational campaign aims to better understand and describe the multiwavelength data, the


Doppler images in Balmer, He i, He ii and C ii lines, and simultaneous I-band photometry of the polar MR Ser are presented and analyzed. The Balmer and Helium Doppler tomograms, of this bright polar



Simultaneous Extreme-Ultraviolet and Infrared Observations of the Eclipsing Polar HU Aquarii

We present simultaneous EUV and infrared (J, K) observations of the polar HU Aquarii obtained during 1998 August when the star was in a high mass accretion state. EUV and IR light curves and EUV

Far-Ultraviolet Spectroscopy of Magnetic Cataclysmic Variables*

We have obtained Hubble Space Telescope (HST) STIS data for a total of 11 polars as part of a program aimed at compiling a homogeneous database of high-quality far-ultraviolet (FUV) spectra for a

Extreme Ultraviolet Explorer Phase-resolved Spectroscopy of V834 Centauri

The Extreme Ultraviolet Explorer (EUVE) satellite was employed for 5.46 days, beginning on 1999 February 9.03 UT, to acquire phase-resolved EUV photometric and spectroscopic observations of the AM

XMM-Newton observations of polars in low accretion states

We have made a series of snap-shot observations of 37 polars using XMM-Newton. We found that 16 of these systems were in a low, or much reduced, accretion state. Of those, six were not detected in
