Unveiling the X-Ray Properties of the Eclipsing Cataclysmic Variable UU Aqr: Spatially and Spectrally Resolved Two-component Emission

The Astrophysical Journal
Nonmagnetic cataclysmic variables (CVs) show two distinct X-ray components: a hard, optically thin component and a soft, optically thick, blackbody-like component, both produced in the boundary layer between the accretion disk and the white dwarf (WD ...

An Equipotential Disk Model with Irradiation for Nova-like Variables

The Astrophysical Journal
The reflection effect is here incorporated within an earlier analytic binary system light- and velocity-curve model that includes a circumstellar equipotential disk.

Balmer decrements as a new diagnostic for period-bounce cataclysmic variable stars

Astronomy & Astrophysics
Context. Cataclysmic variable stars (CVs) evolve towards shorter orbital periods (Porb) until they reach a minimum Porb of ∼80 min. Beyond this point, the donor star becomes out of thermal equilibrium or increasingly degenerate, causing the system to ...

Sonification of Kepler Field SU UMa Cataclysmic Variable Stars V344 Lyr and V1504 Cyg [PDF]

, 2012
Sonification is the conversion of quantitative data into sound. In this work we explain the methods used in the sonification of light curves provided by the Kepler instrument from Q2 through Q6 for the cataclysmic variable systems V344 Lyr and V1504 Cyg .

Stunted Outbursts and Z Cam–like Behaviors in the Long-term Light Curves of Novalike Cataclysmic Variables

The Astrophysical Journal Supplement Series
A program of long-term ground-based photometric monitoring of 134 old novae and novalike cataclysmic variables (CVs) has been concluded. In this paper, we display, analyze, and discuss the light curves of 33 of these targets, which have shown “stunted ...

Detection of Transitions between Dwarf Nova Outbursts, Standstills, and IW And–type Cycles

The Astrophysical Journal
IW And–type objects represent a rare and intriguing subclass of cataclysmic variables that challenge the classical disk instability model. Due to their long timescales, often lasting several months, observed samples are scarce, leaving the physics of ...

Investigation of the new cataclysmic variable 1RXS J180834.7+101041

, 2020
We present the results of our photometric and spectroscopic studies of the new eclipsing cataclysmic variable star 1RXS J180834. 7+101041. Its spectrum exhibits double-peaked hydrogen and helium emission lines.
