Dwarf noave have relatively small amplitude outbursts repeating in timescales between days and many years.

  • Example of a dwarf nova GK Perseii (Evans et al. 2009) : detection of an outburst led to Swift, UV and X-rays follow up. It revealed unusual outburst in the optical but typical outburst in X, challenging existing disc outburst models.
