Nova-like (NL) cataclysmic variables have persistently high mass transfer rates and prominent steady state accretion disks. We present an analysis of infrared observations of 12 NLs obtained from the Two Micron All Sky Survey, the Spitzer Space Telescope, and the Wide-field Infrared Survey Explorer All Sky Survey. The presence of an infrared excess at λ ≳ 3-5 μm over the expectation of a theoretical steady state accretion disk is ubiquitous in our sample. The strength of the infrared excess is… 
Structure of accretion flows in the nova-like cataclysmic variable RW Tri
We obtained photometric observations of the nova-like cataclysmic variable RW Tri and gathered all available AAVSO and other data from the literature. We determined the system parameters and found
Cataclysmic variables: New frontiers in multi-wavelength research
Compact binary systems in which a white dwarf (WD) accretes material from a non-degenerate companion, constitute some of the most prevalent, yet intriguing astronomical objects in the universe. Of
Structure of accretion flows in nova-like cataclysmic variables: RW Sextantis and 1RXS J064434.5+334451
New time-resolved optical spectroscopic echelle observations of the nova-like cataclysmic variable RW Sextantis were obtained, with the aim to study the properties of emission features in the system.
Binary orbits as the driver of γ-ray emission and mass ejection in classical novae
TLDR
High-resolution radio imaging of the γ-ray-emitting nova V959 Mon finds that its ejecta were shaped by the motion of the binary system: some gas was expelled rapidly along the poles as a wind from the white dwarf, while denser material drifted out along the equatorial plane, propelled by orbital motion.
Early Spectral Evolution of Classical Novae: Consistent Evidence for Multiple Distinct Outflows
The physical mechanism driving mass ejection during a nova eruption is still poorly understood. Possibilities include ejection in a single ballistic event, a common envelope interaction, a continuous
The WISE Light Curves of Z Camelopardalis during Outburst: Evidence for Synchrotron Emission?
The WISE mission happened to observe the cataclysmic variable Z Cam at the peak of an outburst. The WISE single exposure data shows that Z Cam was highly variable at 12 μm, but only marginally so at
X-ray spectroscopy of the γ-ray brightest nova V906 Car (ASASSN-18fv)
Shocks in gamma-ray emitting classical novae are expected to produce bright thermal and non-thermal X-rays. We test this prediction with simultaneous NuSTAR and Fermi/LAT observations of nova V906
A WISE view of novae - I. The data
We present the results of data-mining the Wide-field Infrared Survey Explorer (WISE) archive for data on classical and recurrent novae. We find that the detections are consistent with dust emission,

Excess mid-infrared emission in cataclysmic variables
We present a search for excess mid-IR emission due to circumbinary material in the orbital plane of cataclysmic variables (CVs). Our motivation stems from the fact that the strong braking exerted by

We present K-band spectra of the short-period dwarf novae YZ Cnc, LY Hya, BK Lyn, T Leo, SW UMa and WZ Sge, the nova-like variables DW UMa, V1315 Aql, RW Tri, VY Scl, UU Aqr and GP Com, and a series
Ultraviolet Spectra of Cataclysmic Variable Accretion Disks with Nonsteady T(r) Laws
An extensive grid of synthetic mid- and far-ultraviolet spectra for accretion disks in cataclysmic variables has been presented by Wade & Hubeny. In those models, the disk was assumed to be in steady

We have used the PACS instrument on the Herschel Space Observatory to observe eight cataclysmic variables at 70 and 160 μm. Of these eight objects, only AM Her was detected. We have combined the

We have developed a spectrum synthesis method for modeling the ultraviolet (UV) emission from the accretion disk from cataclysmic variables (CVs). The disk is separated into concentric rings, with an

Detection of radio emission from a nova‐like cataclysmic variable: evidence of jets?
Jets have been detected in many accreting compact objects, and recently indications for jets have finally been found for transient cataclysmic variables (dwarf novae). However, so far, there have
