    A 15.7-minAM CVn binary discovered in K2

    We present the discovery of SDSS J135154.46-064309.0, a short-period variable observed using 30-mincadence photometry in K2 Campaign 6. Follow-up spectroscopy...

    A correlation between H α trough depth and inclination in quiescent X-ray transients: evidence for a low-mass black hole in GRO J0422+32

    We present a new method to derive binary inclinations in quiescent black hole (BH) X-ray transients (XRTs), based on the depth of the trough (T) from double...

    A flickering study of nova-like systems KR Aur and UU Aqr

    We present a study of the flickering activity in two nova-like systems, KR Aur and UU Aqr. We applied a statistical model of flickering simulations in accretion...

    A FWHM–K2 Correlation in Black Hole Transients

    We compare {{{H}}}α emission profiles of 12 dynamically confirmed black holes (BHs) and 2 neutron star X-ray transients (SXTs) in quiescence with those of a...

    BG Tri: an example of a low-inclination RW Sex-type nova-like

    We analyse a wealth of optical spectroscopic and photometric observations of the bright (V = 11.9) cataclysmic variable BG Tri. The Gaia DR2 parallax gives a...

    Cyclic brightening in the short-period WZ Sge-type cataclysmic variable SDSS J080434.20+510349.2

    Aims: We observed a new cataclysmic variable (CV) SDSS J080434.20+510349.2 to study the origin of long-term variability found in its light curve. Methods: Multi...

    Discovery of an eclipsing dwarf nova in the ancient nova shell Te 11

    We report on the discovery of an eclipsing dwarf nova (DN) inside the peculiar, bilobed nebula Te 11. Modelling of high-speed photometry of the eclipse finds...
