  26. Summary • Disc instability model: • under predicts quiescent accretion rate by >100x • fails to explain outbursts in SS Cyg • Origin of outburst X-ray emission unknown • MRI-driven corona? • Shocks in outflows/jets? • Jets, outflows and QPOs all detected in CVs • models for BHs/NSs must also work for white dwarfs • Galactic ridge X-ray emission: • contribution of non-magnetic CVs previously underestimated
