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.

DETERMINATION OF SIZE OF THE EMITTING REGION IN ECLIPSING CATACLYSMIC VARIABLE STARS
Odessa Astronomical Publications, 2014 The dependencies of the phase of eclipse of the white dwarf’s centre and the durations of the ascending and descending branches of the light curve on the binary system’s parameters were computed using the spherically symmetric approximation and the more ...

Optical Studies of Seven Bright Southern Cataclysmic Variable Stars
The Astronomical Journal, 2023 We report spectroscopic observations of seven bright southern cataclysmic variable stars, collected on a single two-week observing run using the 1.9 m Radcliffe telescope at the South African Astronomical Observatory.

Cataclysmic Variables as Binary Stars: Then and Now [PDF]
International Astronomical Union Colloquium, 1990 AbstractA brief history is given of the clues that led to the establishment, in the period c. 1950 to 1965, of a universal binary model for novae and related cataclysmic variables. The observational facts, established early in this period by A. H. Joy and R. F. Sanford (selected binary orbits), J. L. Greenstein (spectroscopy) and M. Walker (photometry)

CCD Photometry Using Multiple Comparison Stars [PDF]
Journal of Astronomy and Space Sciences, 2004 The accuracy of CCD observations obtained at the Korean 1.8 m telescope has been studied. Seventeen comparison stars in the vicinity of the cataclysmic variable BG CMi have been measured.

CCD-PHOTOMETRY OF CATACLYSMIC VARIABLE ES DRA IN 2001
Odessa Astronomical Publications, 2017 On the base of our 34-day photometry of ES Dra we found its ∼ 20 d light variations with amplitude of 1m.6 and suggest this star could belong to the nova-like subclass of cataclysmic variable stars.

The Periods of Cataclysmic Variable Stars [PDF]
International Astronomical Union Colloquium, 1983 To understand the structure and evolution of the cataclysmic variables, we will need accurate values for their masses, dimensions, mass transfer rates, and other physical properties. Unfortunately, despite an abundance of observational data on these systems, there is a severe dearth of reliable, quantitative information about their fundamental physical

”ASYMPTOTIC PARABOLA” FITS FOR SMOOTHING GENERALLY ASYMMETRIC LIGHT CURVES
Odessa Astronomical Publications, 2016 A computer program is introduced, which allows to determine statistically optimal approximation using the "Asymptotic Parabola" fit, or, in other words, the spline consisting of polynomials of order 1,2,1, or two lines ("asymptotes") connected with a ...
