White Dwarfs in Cataclysmic Variables: An Update [PDF]
Acta Polytechnica CTU Proceedings, 2015 In this review, we summarize what is currently known about the surface temperatures of accreting white dwarfs in nonmagnetic and magnetic cataclysmic variables (CVs) based upon synthetic spectral analyses of far ultraviolet data.

Magnetic Cataclysmic Variables [PDF]
AIP Conference Proceedings, 2010 We present a study on magnetic cataclysmic variables (polars) using the collected data from the literature. These parameters (mass, radius, magnetic field intensity, mass transfer rate, etc.) and the relations between them are important to understand their nature, to explain the observed properties of them and to test the current evolutionary models.

White Dwarfs in Cataclysmic Variable Stars: Surface Temperatures and Evolution [PDF]
Journal of Astronomy and Space Sciences, 2012 A summary is presented of what is currently known about the surface temperatures of accreting white dwarfs (WDs) detected in non-magnetic and magnetic cataclysmic variables (CVs) based upon synthetic spectral analyses of far ultraviolet data.

Cataclysmic Variables as Supernova Ia Progenitors [PDF]
Journal of Astronomy and Space Sciences, 2012 Although the identification of the progenitors of type Ia supernovae (SNeIa) remains controversial, it is generally accepted that they originate from binary star systems in which at least one component is a carbon-oxygen white dwarf (WD); those systems ...

The Accreting White Dwarfs in Cataclysmic Variables
Galaxies, 2022 Accreting white dwarfs (WDs) in cataclysmic variables (CVs) provide crucial insights about the accretion of mass and angular momentum in all types of binaries, including accreting NSs and BHs.

Transients from the Cataclysmic Deaths of Cataclysmic Variables [PDF]
The Astrophysical Journal, 2021 Abstract We explore the observational appearance of the merger of a low-mass star with a white dwarf (WD) binary companion. We are motivated by recent work finding that multiple tensions between the observed properties of cataclysmic variables (CVs) and standard evolution models are resolved if a large fraction of CV binaries merge as a ...

ESA INTEGRAL and Cataclysmic Variables
Odessa Astronomical Publications, 2017 The satellite INTEGRAL is ESA project operating since January 2003. It is dedicated to high energy astronomy. INTEGRAL is able to detect and perform astrometry, photometry and spectroscopy of sources from X-ray to gamma-ray regime (nominal range of ...

Contemporary Physics, 2006 Cataclysmic variables are binary stars in which a relatively normal star is transferring mass to its compact companion. This interaction gives rise to a rich range of behaviour, of which the most noticeable are the outbursts that give the class its name. Novae belong to the class, as do the less well known dwarf novae and magnetic systems.

Golden Era of Cataclysmic Variables and Related Objects II: Concluding Remarks
Acta Polytechnica CTU Proceedings, 2015 The cataclysmic variables continue to represent important part of modern astrophysics, as demonstrated, already second time, by the productive and successful conference Golden Era of Cataclysmic Variables and Related Objects II held on Mondello (Palermo)
