Magnetic cataclysmic variable accretion flows [PDF]
AIP Conference Proceedings, 2007 We have used a magnetic accretion model to investigate the accretion flows of magnetic cataclysmic variables (mCVs) throughout a range of parameter space. The results of our numerical simulations demonstrate that broadly four types of flow are possible: discs, streams, rings and propellers. We show that the equilibrium spin periods in asynchronous mCVs,

OBSERVATIONS OF CATACLYSMIC VARIABLES AT KOLONICA OBSERVATORY
Odessa Astronomical Publications, 2007 We present a small sample of our observations of cataclysmic variable stars obtained at Kolonica Observatory, The presented data for CI UMa, MR UMa and SW UM were obtained in 2006 and 2007. Our observations demonstrate that also the small telescopes with

Accretion in Cataclysmic Variable Stars [PDF]
, 2005 We consider accretion onto the white dwarfs in cataclysmic variables in relation to nova eruptions, dwarf nova outbursts, hibernation and non-radial oscillations.

Accretion in magnetic cataclysmic variables [PDF]
Astrophysics and Space Science, 1987 AbstractWe discuss the arguments in favour of the suggestion that polars (AM Her systems) and intermediate polars (IP’s) have magnetic fields of the same order of magnitude, and form one single class of objects. The period distribution of magnetic cataclysmic variables is well explained if they evolve the same way as non magnetic systems, IP’s becoming

Automatic Search of Cataclysmic Variables Based on LightGBM in LAMOST-DR7
Universe, 2021 The search for special and rare celestial objects has always played an important role in astronomy. Cataclysmic Variables (CVs) are special and rare binary systems with accretion disks.

Cataclysmic Variable Stars [PDF]
Highlights of Astronomy, 1998 The evolution of single stars on and away from the main sequence is well understood. A degenerate core is formed in a star as the star leaves the main sequence and expands to a giant with a radius typically 50 - 500 Ro . Observationally it is known that most stars are members of binary systems, and among these many have orbital periods less than 100 y.

Theoretical spectra of cataclysmic variables [PDF]
Astrophysics and Space Science, 1987 AbstractWe present two methods of modelling accretion disks in dwarf novae. The first one determines self-consistently the structure of a disk together with the radiation field. The computed theoretical spectra agree well with the observations of the dwarf nova WX Hyi in quiescence as well as in superoutburst.

The Ritter-Kolb Catalogue and its Impact on Research into CVs, LMXBs and related Objects
Acta Polytechnica CTU Proceedings, 2015 In the first part of this paper, the Ritter-Kolb catalogue (RKcat for short), its history and a few examples of its application to research in the field of cataclysmic variables are briefly described.

Observations of faint eclipsing cataclysmic variables [PDF]
New Astronomy, 2010 We present time-resolved photometry of six faint (V>17mag) cataclysmic variables (CVs); one of them is V849 Oph and the others are identified from the Sloan Digital Sky Survey (SDSS J0920+0042, SDSS J1327+6528, SDSS J1227+5139, SDSS J1607.02+3623, SDSS J1457+5148). The optical CCD photometric observations of these objects were performed at the T B

The hybrid Nova Vul 2024 (=V615 Vul)
Astronomy & AstrophysicsContext. Among galactic novae, many remain poorly characterized due to heterogeneous data, observational challenges, or heavy reddening along the Galactic plane.
