Detached cataclysmic variables are crossing the orbital period gap [PDF]
, 2016 A central hypothesis in the theory of cataclysmic variable (CV) evolution is the need to explain the observed lack of accreting systems in the ~2-3 h orbital period range, known as the period gap.

The Periods of Cataclysmic Variables [PDF]
International Astronomical Union Colloquium, 1987 AbstractThe present status of the period studies of cataclysmic variables is briefly reviewed, mainly from the observational point of view. A few comments on individual objects include EM Cyg, Z Cha, WZ Sge and AM CVn.

, 2015 We present our wide field Halpha+N[II] observations of 15 cataclysmic variables to search for remnant nova shells. Such shells have been found around other cataclysmic variables that were hitherto not known as novae.

BLOB PARAMETERS OF ACCRETION STREAMS IN MAGNETIC CATACLYSMIC VARIABLES
Odessa Astronomical Publications, 2017 Results of investigations of the autocorrelation functions for two magnetic cataclysmic variables BY Cam and QQ Vul are presented. Significant variations of this characteristic are detected. They are interpreted as caused by variations of the blob length

Radio emission from cataclysmic variables [PDF]
Astrophysics and Space Science, 1987 AbstractThe study of radio emission from cataclysmic variables (CVs) is a new and developing field. Radio emission from novae, recurrent novae, dwarf novae and each of the subclasses (AM Her and OQ Her) of magnetic CVs have now been reported and are reviewed here.

Rotation and Cataclysmic Variables [PDF]
Symposium - International Astronomical Union, 2004 Cataclysmic Variables are binary star systems and so are closely connected to the subject of this meeting. The stars revolve around the center of mass of the system. The gas lost by the secondary through the inner Lagrangian point enters the Roche lobe of the white dwarf with the angular momentum of the L1point and, therefore, forms an accretion disk ...

JCMS: Journal of Common Market Studies, Volume 64, Issue 3, Page 1048-1068, May 2026.Abstract The 2016 Brexit referendum was a watershed moment for the politicisation of the European Union (EU) in the United Kingdom. Much has been written about the politicising effects of the referendum, along with the Leave result's subsequent contestation in the media as well as in national and European election cycles.

Rapid Keck Spectroscopy of Cataclysmic Variables [PDF]
International Astronomical Union Colloquium, 2004 Abstract We present an analysis of Rapid Keck Spectroscopy of the CVs AM Her (polar) and SS Cyg (dwarf nova). We decompose the spectra into constant and variable components and identify different types of variability in AM Her with different characteristic timescales.

A strike for democracy? Migration, the bigot's veto, and the electoral use of force
American Journal of Political Science, Volume 70, Issue 2, Page 491-502, April 2026.Abstract Politicians and philosophers alike have warned that the spread of anti‐migrant bigotry in the Western world requires a tragic trade‐off regarding immigration policy: Although millions of asylum‐seekers might be owed admission to Western democracies, there are many cases where they nonetheless ought to be denied entry, because their admission ...

X-ray sources in globular clusters
, 2004 Observations with BeppoSAX, RXTE and Chandra suggest that many of the bright X-ray sources in globular clusters have ultrashort binary periods. This is remarkable as such systems are not easily formed.
