    Mass Ratio Determination from H α Lines in Black Hole X-Ray Transients
    We find that the mass ratio q in quiescent black hole (BH) X-ray transients is tightly correlated with the ratio of the double-peak separation (DP) to the full...

    Multifrequency behaviour of the dwarf nova SS Cygni
    Coordinated multifrequency observations of the dwarf nova SS Cygni have been performed for several years in order to study the accretion behavior of this system...

    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...

    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...

    Quiescent and outburst photometry of the dwarf nova SS Cygni
    Photometric observations of a wide and a narrow outburst of the dwarf nova SS Cygni are used to test the hypothesis that the same mechanism is responsible for...

    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...
