OutburstsSeveral IPs have shown occasional, very short, outbursts. Several lines of evidence points to these being episodes of enhanced accretion rate from the secondary.
GK Per, an anomalous system in many respects, has very long outbursts, possibly related to the long orbital period of this system.
For now, the outburst of WZ Sge is not included on this page. If it is confirmed as a true dwarf nova, we need an explanation for why the outburst is prototypical of its subclass, unlike the outbursts of several other short-period IPs.
