The Secondary Stars of Cataclysmic Variables
, 2011 I review what we know about the donor stars in cataclysmic variables (CVs), focusing particularly on the close link between these binary components and the overall secular evolution of CVs. I begin with a brief overview of the "standard model" of CV evolution and explain why the key observables this model is designed to explain - the period gap and the

Irradiation of the companion star in cataclysmic variables [PDF]
Monthly Notices of the Royal Astronomical Society, 1989 Il est demontre que le rayonnement de l'ecoulement d'accretion au niveau de la naine blanche dans une binaire cataclysmique est incapable de penetrer la photosphere du compagnon. Le rayonnement peut, dans quelques cas, ioniser l'ecoulement d'accretion subsonique juste en dessous du point de Lagrange ...

Resolving the Periods of the Asynchronous Polar 1RXS J083842.1–282723
The Astrophysical Journal1RXS J083842.1−282723 is a nearly synchronous magnetic cataclysmic variable with a simple X-ray light curve. While its orbital period was fairly well established at P _orb = 98.4 minutes from optical spectroscopy, indirect estimates of P _spin / P _orb ...

Stepanyan's star - A new eclipsing cataclysmic variable
The Astrophysical Journal, 1980 High-speed photometry of the nova-like variable Stepanyan's star shows a 3-hr 48-min orbital period marked by a 2.2-mag eclipse which spans orbital phases 0.91-0.09. The uneclipsed light is variable by typically 0.15 mag on time scales of minutes to seconds and shows no obvious modulation with orbital phase. Intermediate-band colors show an enhancement

Soft X-Ray Observations of Cataclysmic Variable Stars [PDF]
International Astronomical Union Colloquium, 1979 HEAO-1 observations of a large number of cataclysmic variable stars demonstrated that most of these objects are not bright X-ray sources, even during their eruptive phases.HEAO-1 scanned about 20 dwarf novae while they were undergoing optical outbursts, yet soft X-ray emission (0.18-0.43 keV) was detected only from SS Cyg and U Gem. The 3σ upper limits

The Eclipsing Novalike Cataclysmic Variable CRTS SSS100505 J093417-174421
The Astrophysical JournalTime-resolved optical photometry, complemented by Transiting Exoplanet Survey Satellite (TESS) data and long-term survey light curves, reveals that the transient object CRTS SSS100505 J093417-174421 is an eclipsing novalike cataclysmic variable of the VY

The Long-term Activity of the Postnovae Q Cygni and BK Lyncis
The Astronomical JournalWe show the postnova activity of Q Cyg (Nova Cyg 1876) and BK Lyn (probable Nova Lyn 101). We use both CCD and photographic photometric observations.

On the eclipsing cataclysmic variable star HBHA 4705-03
, 2013 We present observations and analysis of a new eclipsing binary HBHA 4705-03. Using decomposition of the light curve into accretion disk and hot spot components, we estimated photometrically the mass ratio of the studied system to be q=0.62 +-0.07. Other fundamental parameters was found with modeling. This approach gave: white dwarf mass M_1 = (0.8 +- 0.
