Temporary Equilibrium Mass Transfer Rate in Cataclysmic Variables?
The Astrophysical JournalThe separation of a binary system increases or decreases over time, governed by angular momentum (AM) changes. In cataclysmic variables (CVs), Roche-lobe overflow from the red dwarf (RD) to the white dwarf (WD) redistributes AM within the system through ...

Odessa Astronomical Publications, 2016 We present a technique for simultaneous measurement of circular and linear polarization with the single-channel polarimeter, that is used in Crimean astrophysical observatory for many years. Methods and a computer program for data reduction is described.

Cyclical Period Changes in Cataclysmic Variables: A Statistical Study
The Astrophysical JournalWe report the results of a statistical study of cyclical period changes in cataclysmic variables (CVs). Assuming the third-body hypothesis as the cause of period changes, we estimate the third-body mass, m _3 , and its separation from the binary, a _3 ...

Telescope and Researcher Potential of Turkey for Collaboration in CV Studies
Open Astronomy, 2012 Turkish astronomical community has witnessed the construction of several telescopes in the last 10 years. These telescopes and the potential of young researchers in the country motivated this poster presentation which aims to receive attention for ...

DETERMINATION OF THE ORIENTATION OF THE ACCRETION COLUMNS IN MAGNETIC CATACLYSMIC VARIABLES
Odessa Astronomical Publications, 2017 Methods for the determination of the orientation of accretion columns in magnetic cataclysmic variables based on the observations of the circular and linear polarization, X-Ray flux and profiles of emission lines are discussed.

TESS Light Curves of Cataclysmic Variables. VI. Intermediate Polars
The Astrophysical Journal Supplement SeriesThe long and (almost) continuous high-cadence light curves provided by the TESS space mission are ideally suited to study in detail brightness variations in stellar sources on the broad range of timescales between minutes and months.

The Golden Age of Cataclysmic Variables and Related Objects - II Concluding Address
Acta Polytechnica CTU Proceedings, 2015 Before to conclude officially this workshop — far from me the idea to attempt some concluding remarks already dealt at the meeting with various burning by Joseph Patterson, Mariko Kato, Dmitry Bisikalo, and Rene Hudec —, I would like to comment few ...

The boundary layer in cataclysmic variables [PDF]
Astrophysics and Space Science, 1987 AbstractRecent development in the theory of the boundary layer is considered. The model for the formation of a corona above the WD is discussed in some detail.The interaction of the boundary layer with the stellar interior and possible mixing between the hydrogen-rich accreted matter and the core material is discussed in view of recent numerical ...

Binary Star Database (BDB): New Developments and Applications
Data, 2018 Binary star DataBase (BDB) is the database of binary/multiple systems of various observational types. BDB contains data on physical and positional parameters of 260,000 components of 120,000 stellar systems of multiplicity 2 to more than 20, taken from a

The donor stars of cataclysmic variables [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 Abstract We carefully consider observational and theoretical constraints on the global properties of secondary stars in cataclysmic variable stars (CVs). We then use these constraints to construct and test a complete, semi-empirical donor sequence for CVs with orbital periods Porb≤ 6 h.
