    Swift X-Ray and Ultraviolet Monitoring of the Classical Nova V458 Vul (Nova Vul 2007)
    We describe the highly variable X-ray and UV emission of V458 Vul (Nova Vul 2007), observed by Swift between 1 and 422 days after outburst. Initially bright...

    SWSextantis stars: the dominant population of cataclysmic variables with orbital periods between 3 and 4h
    We present time-series optical photometry of five new cataclysmic variables (CVs) identified by the Hamburg Quasar Survey (HQS). The deep eclipses observed in...

    SY Cnc, a case for unstable mass transfer?
    Intermediate-resolution (0.5-1 Å) optical spectroscopy of the cataclysmic variable (CV) SY Cnc reveals the spectrum of the donor star. Our data enable us to...

    The distances of the Galactic novae
    Utilizing the unique location of red clump giants on colour-magnitude diagrams obtained from various near-infrared surveys, we derived specific reddening...

    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...
