Discovery of a bright eclipsing cataclysmic variable
Aims. We report on the discovery of J0644+3344, a bright deeply eclipsing cataclysmic variable (CV) binary. Methods. Optical photometric and spectroscopic observations were obtained to determine the nature and characteristics of this CV. Results. Spectral signatures of both binary components and an accretion disk can be seen at optical wavelengths. The optical spectrum shows broad H I, He I, an...
متن کاملAccretion in Cataclysmic Variable Stars
We consider accretion onto the white dwarfs in cataclysmic variables in relation to nova eruptions, dwarf nova outbursts, hibernation and non-radial oscillations.
متن کاملULTRACAM observations of SDSS J170213.26+322954.1– an eclipsing cataclysmic variable in the period gap
We present high-speed, three-colour photometry of the eclipsing cataclysmic variable SDSS J170213.26+322954.1 (hereafter SDSS J1702+3229). This system has an orbital period of 2.4 hours, placing it within the “period gap” for cataclysmic variables. We determine the system parameters via a parameterized model of the eclipse fitted to the observed light curve by χ minimization. We obtain a mass r...
متن کاملThe eclipsing Cataclysmic Variable GS Pavonis : Evidence for disk radius changes ⋆
We have obtained differential time series photometry of the cataclysmic variable GS Pavonis over a timespan of 2 years. These show that this system is deeply eclipsing (∼2– 3.5 mag) with an orbital period of 3.72 hr. The eclipse depth and out-of-eclipse light levels are correlated. From this correlation we deduce that the disk radius is changing and that the eclipses in the low state are total....
متن کاملFITDisk: A Cataclysmic Variable Accretion Disk Demonstration Tool
We present the software tool FITDisk, a precompiled-binary Windows GUI version of our smoothed particle hydrodynamics cataclysmic variable accretion disk research code. Cataclysmic variables are binary star systems in which a compact stellar remnant, typically a white dwarf star, is stripping mass from a lower-main-sequence companion star by way of an accretion disk. Typically the disk is the b...
