A New Window for Studying Intermediate Polars and Tilted Accretion Disk Precession
TV Col is a long-period eclipsing intermediate polar (IP) prototype star for the negative superhump (NSH) system. We investigate the eclipse minima, eclipse depth, and NSH amplitude based on TESS photometry.

Gas flow in cataclysmic variable stars
A numerical hydrodynamic scheme, applicable to gas flow in binary stars, is presented which incorporates the effects of pressure and gravitational forces, radiative cooling, and shock formation. The method is used to study gas flow originating from Roche lobe overflow through the inner Lagrangian point, L$sub 1$, in a binary star modeled to resemble ...

Compact objects undergoing mass transfer exhibit significant (and double-peaked) H _α emission lines. Recently, new methods have been developed to identify black hole X-ray binaries and calculate their systematic parameters using H _α line parameters ...

EUVE J0854+390: a new Cataclysmic Variable [PDF]
We report the identification of a new CV in the field of EUVE J0854+390. The optical spectra show Balmer, He I and He II lines strongly in emission and indicates the source is a CV, probably magnetic.Information Bulletin on Variable Stars 5032(1).

Time-resolved spectroscopy of the AM Herculis-type binary systems QQ VUL and EF ERI
Cataclysmic variable stars (CVs) are interacting binary systems. One of the stars (referred to as the primary) is a white dwarf, the other (referred to as the secondary) is usually a late main sequence star such as a red dwarf.

Optical identification of IGR J18308-1232 as a cataclysmic variable [PDF]
We report on a spectroscopic analysis of optical sources inside the error circle of the XMM-Newton slew source XMMLS1 J183049.6-123218 (see Ibarra et al., ATel #1527), associated with the unidentifiedINTEGRAL source IGR J18308-1232 (Bird et al.

1RXS J173021.5-055933 : a cataclysmic variable with a fast-spinning magnetic white dwarf [PDF]
Aims. We present the first X-ray observations with the XMM-Newton and INTEGRAL satellites of the recently discovered cataclysmic variable 1RXS J173021.5-055933, together with simultaneous UV and coordinated optical photometry aiming at characterising its

Resolving the Periods of the Asynchronous Polar 1RXS J083842.1–282723
1RXS 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 ...
