    Erratum to ATel #2166
    The observations we reported in ATel #2166 were actually of nova M31 2009-08b, not 2009-08d. Therefore, ATel #2166 confirms the nova nature of nova M31 2009-08b...

    Evidence for mass accretion driven by spiral shocks onto the white dwarf in SDSS J123813.73-033933.0
    We present high-time-resolution photometry and phase-resolved spectroscopy of the short-period ({P_orb}= 80.52 min) cataclysmic variable SDSS J123813.73-033933...

    Evidence of Magnetic Accretion in an SW Sextantis Star: Discovery of Variable Circular Polarization in LS Pegasi
    We report on the discovery of variable circular polarization in the SW Sextantis star LS Pegasi. The observed modulation has an amplitude of ~0.3% and a period...

    EX draconis: using eclipses to separate outside-in and inside-out outbursts
    We present a study of the eclipses in the accreting white dwarf EX draconis (EX Dra) during TESS Cycles 14 and 15. During both of the two outbursts present in...

    Exploring the tilted accretion disc of AQ Men with TESS
    AQ Men is a nova-like variable that is presumed to have a tilted, precessing accretion disc. Grazing eclipses in this system have been speculated to be useful...

    Fast quasi-periodic oscillations in the eclipsing polar VV Puppis from VLT and XMM-Newton observations
    We present high time resolution optical photometric data of the polar VV Puppis obtained simultaneously in three filters (u', HeII λ4686, r') with the ULTRACAM...

    First detections of the cataclysmic variable AE Aquarii in the near to far infrared with ISO and IRAS: Investigating the various possible thermal and non-thermal contributions
    We have used ISO to observe the Magnetic Cataclysmic Variable AE Aquarii in the previously unexplored range from 4.8 μm up to 170 μm in the framework of a...

    Fourier time lags in the dwarf nova SS Cygni
    To understand the physical processes governing accretion discs we can study active galactic nuclei (AGNs), X-ray binary systems (XRBs), and cataclysmic...

    Galactic evolution of the light-element isotopes
    The galactic evolution of the abundances of the light-element isotopes (6Li, 7Li, 9Be, 10B, and 11B) is re-examined in view of recent measurements of the 7Li...
