    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...

    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...

    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...

    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...

    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...

    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...

    Roche tomography of cataclysmic variables - VI. Differential rotation of AE Aqr - not tidally locked!
    We present Roche tomograms of the K4V secondary star in the cataclysmic variable AE Aqr, reconstructed from two data sets taken 9 d apart, and measure the...

    Roche tomography of cataclysmic variables - VII. The long-term magnetic activity of AE Aqr
    We present a long-term study of the secondary star in the cataclysmic variable AE Aqr, using Roche tomography to indirectly image starspots on the stellar...
