    SDSS J105754.25+275947.5: a period-bounce eclipsing cataclysmic variable with the lowest-mass donor yet measured
    We present high-speed, multicolour photometry of the faint, eclipsing cataclysmic variable (CV) SDSS J105754.25+275947.5. The light from this system is...

    SDSS unveils a population of intrinsically faint cataclysmic variables at the minimum orbital period
    We discuss the properties of 137 cataclysmic variables (CVs) which are included in the Sloan Digital Sky Survey (SDSS) spectroscopic data base, and for which...

    Spectroscopic and photometric periods of six ultracompact accreting binaries
    Ultracompact accreting binary systems each consist of a stellar remnant accreting helium-enriched material from a compact donor star. Such binaries include two...

    Spectroscopic observations of V455 Andromedae superoutburst in 2007: The most exotic spectral features in dwarf nova outbursts
    We present our spectroscopic observations of V455 Andromedae during the 2007 superoutburst. Our observations cover this superoutburst from around the optical...

    The cataclysmic variable SS Cygni
    A general panorama of SS Cygni is presented. The paper first describes the CV cataclysmic variables and the current theories which attempt to describe their...

    The donor star radial velocity curve in the cataclysmic variable GY Cnc confirms white dwarf eclipse modelling mass
    A large number of white dwarf and donor masses in cataclysmic variables have been found via modelling the primary eclipse, a method that relies on untested...

    The evolutionary status of Cataclysmic Variables: eclipse modelling of 15 systems
    We present measurements of the component masses in 15 Cataclysmic Variables (CVs) - 6 new estimates and 9 improved estimates. We provide new calibrations of the...
