Superoutburst : a general phenomenon in dwarf novae.
Abstract
The occurrence of a bimodal distribution of outburst durations is a general property of dwarf novae. The intrinsic duration of the long outbursts is not correlated with the orbital period, that of short outbursts tends to increase with orbital period. The impressive contrast between the short and long outbursts in SU UMa type systems is a consequence of this, in combination with the positive correlation between the decay time of the outbursts and the orbital period (Bailey relation). Thus the restriction of the term "superoutburst" to short-orbital-period systems is misleading.
