    Orbital periods of cataclysmic variables identified by the SDSS - III. Time-series photometry obtained during the 2004/5 International Time Project on La Palma
    We present time-resolved CCD photometry of 15 cataclysmic variables (CVs) identified by the Sloan Digital Sky Survey (SDSS). The data were obtained as part of...

    Orbital periods of cataclysmic variables identified by the SDSS. VI. The 4.5-h period eclipsing system SDSS J100658.40+233724.4
    We present time-resolved spectroscopy and photometry of SDSS J100658.40+233724.4, which we have discovered to be an eclipsing cataclysmic variable with an...
  • Publication
    Orbital periods of cataclysmic variables identified by the SDSS. VII. Four new eclipsing systems
    We present photometry of nine cataclysmic variable stars identified by the Sloan Digital Sky Survey, aimed at measuring the orbital periods of these systems...

    Phase-resolved spectroscopy of Gaia14aae: line emission from near the white dwarf surface
    AM CVn binaries are a class of ultracompact, hydrogen-deficient binaries, each consisting of a white dwarf accreting helium-dominated material from a degenerate...
  • Publication
    Post common envelope binaries from SDSS. IV. SDSS J121258.25-012310.1, a new eclipsing system
    From optical photometry we show that SDSS J121258.25-012310.1 is a new eclipsing, post common-envelope binary with an orbital period of 8.06 h and an eclipse...
  • Publication
    Post-common-envelope binaries from SDSS - I. 101 white dwarf main-sequence binaries with multiple Sloan Digital Sky Survey spectroscopy
    We present a detailed analysis of 101 white dwarf main-sequence binaries (WDMS) from the Sloan Digital Sky Survey (SDSS) for which multiple SDSS spectra are...
  • Publication
    Radial velocity study of the post-period minimum cataclysmic variable SDSSJ143317.78+101123.3 with an electron-multiplying CCD
    We present high time-resolution spectroscopy of the eclipsing cataclysmic variable SDSSJ143317.78+101123.3 obtained with QUCAM2, a high-speed/low-noise electron...
  • Publication
    Roche tomography of cataclysmic variables - III. Star-spots on AE Aqr
    We present a Roche tomography reconstruction of the secondary star in the cataclysmic variable AE Aqr. The tomogram reveals several surface inhomogeneities that...
  • Publication
    Roche tomography of cataclysmic variables - IV. Star-spots and slingshot prominences on BV Cen
    We present Roche tomograms of the G5-G8 IV/V secondary star in the long-period cataclysmic variable BV Cen reconstructed from Magellan Inamori Kyocera Echelle...
