Doppler tomography of Cataclysmic Variables
The study of cataclysmic variables (CVs), and in particular of the evolution of their accretion discs throughout their different brightness states, has benefited largely from the use of indirect imaging techniques. I report on the latest results obtained from Doppler tomography of CVs concentrating mainly on results published since the 2000 Astrotomography meeting in Brussels. Emphasis is given...
متن کاملDoppler Tomography & Dynamics of Magnetic Structures in Cataclysmic Variables
Preface This report concerns interacting binary stars called cataclysmic variables, or CVs. Two different projects, one more theoretically inclined while the other concerns new observations of CVs, are presented in different chapters and reflect the research I have conducted during my graduation year at Utrecht University to fulfill my research requirements. Chapter 1 introduces the group of bi...
متن کاملFar - ultraviolet Spectroscopy of Magnetic Cataclysmic Variables
We have obtained HST/STIS data for a total of eleven polars as part of a program aimed to compile a homogeneous database of high-quality far-ultraviolet (FUV) spectra for a large number of cataclysmic variables (CVs). Of the eleven polars, eight were found in a state of low accretion activity (V347Pav, VVPup, V834Cen, BLHyi, MRSer, STLMi, RXJ1554.2+2721 and V895Cen) and three in a state of high...
متن کاملCataclysmic variables
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. Novae draw their energy from nuclear reactions, while d...
متن کاملRoche tomography of cataclysmic variables: I. artefacts and techniques
Roche tomography is a technique used for imaging the Roche-lobe filling secondary stars in cataclysmic variables (CVs). In order to interpret Roche tomograms correctly, one must determine whether features in the reconstruction are real, or due to statistical or systematic errors. We explore the effects of systematic errors using reconstructions of simulated datasets and show that systematic err...
