Hi,

WX Hyi has just shown the following sequence of events in succession

1. normal outburst

2. superoutburst

3. another normal (?) outburst, ongoing at this moment.

Phases 1 and 2 do occur in succession with other systems too.

However event 3 seems a bit out of phase. The going theory spells that the superoutburst is the 'complete cleaning' phase, iow all H is burned away.

What happens to WX Hyi then for it still to have another outburst? Is it unstable mass transfer by the secondary triggered by the past s/outburst or is it due to another unrelated activity?

Do I hear 'flickering'?

Regards,

Berto Monard
