The Long Period Dwarf Nova Uy Pup in Outburst
UY Pup is a little studied, frequently outbursting dwarf nova whose brightness varies from V ⋃ 13.5 mag in outburst to V ⋃ 15.8 mag in quiescence, which typically lasts ⋃15...25d. We observed it spectroscopically...

An ASCA observation of the Eclipsing Dwarf Nova HT CAS
We report on a 1-day ASCA observation of the eclipsing dwarf nova HT Cas. We confirm the presence of an X-ray eclipse, which is narrow and deep. The data are consistent with the X-rays originating entirely fro...

The Eclipses of the Close Binary star BE UMa
BE UMa is a close binary star, not transferring mass, with an extremely hot primary star irradiating the inner face of the cool secondary star. The light curve shows a large-amplitude, sinusoidal variation wit...

Line Formation in U Gem and T Leo
We present 3-D LTE radiative transfer calculations [1] for H, He and Ca in accretion disks (AD) of dwarf novae in quiescence. The model disk is assumed to be in hydrostatic equilibrium vertically, and to rotat...

Studies in Flickering
Flickering is a poorly understood phenomenon associated with accretion processes, but this does not suffice to make it interesting. Why then should we bother studying this ‘noise’? Three reasons come to mind: ...

Viscous Evolution of Accretion Discs in the Quiescence of Dwarf Novae
The viscous evolution of accretion discs in the quiescence of dwarf novae is investigated semi-analytically. There are two key factors: the inward flow of the initial mass in the disc and the diffusion of the ...
