WZ Sge-type superoutburst

WZ Sge-type superoutbursts are a kind of superoutbursts observed in SU UMa-type dwarf novae. WZ Sge-type superoutbursts are characterized by i) early superhumps appear during the first few days of the superoutburst, ii) ordinary superhumps appear after early superhumps disappear, iii) a large fading rate in the early superhump phase, compared with that in the superhump phase, iv) a large outburst amplitude of >~ 7 mag, v) a long recurrence time of ~10 yr, vi) rebrightening events after the main superoutburst finishes. WZ Sge-type dwarf novae are dwarf novae which experience this type of superoutburst.
