How thick are CV accretion discs?
Tim Naylor (Keele)
The standard model of low-mass X-ray binaries invokes extensive vertical
structure in their accretion discs to explain features seem in the
lightcurves of eclipsing and near-eclipsing system. These structures
imply opening angles of around 10 degrees. In contrast, the case for such
thickening is controversial for cataclysmic variables. I outline the case
for extensive vertical structure in CV discs, and discuss the implications
for disc mapping.
