On the Origin of Early Superhumps in WZ Sge-Type Stars
Abstract The origin of early superhumps, which are double-wave periodic modulations seen only during the earliest stage of a WZ Sge-type outburst, has not been well understood. Based on a recent discovery of two-armed arch-like patterns on Doppler tomograms in conjunction with early superhumps, we propose a new interpretation on …
