Late Superhumps in WZ Sge-Type Dwarf Novae
Late Superhumps in WZ Sge-Type Dwarf Novae
We report on the detection of very stable modulations with periods unexpectedly (~0.5%) longer than superhump periods during the slowly fading stage of WZ Sge-type superoutbursts in three systems, GW Lib, V455 And and WZ Sge. These periods are naturally explained by assuming that these modulations are superhumps arising from …
