    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...

    Rotational broadening and Doppler tomography of the quiescent X-ray nova Centaurus X-4
    We present high- and intermediate-resolution spectroscopy of the X-ray nova Centaurus X-4 during its quiescent phase. Our analysis of the absorption features...
