EARLY SUPERHUMPS IN THE "KING OF THE SUPEROUTBURSTS" SYSTEM WZ SGE

EARLY SUPERHUMPS IN THE "KING OF THE SUPEROUTBURSTS" SYSTEM WZ SGE

Time series analysis of 6 nights of CCD observations of WZ Sge after it's unexpected superoutburst on July 23, 2001 has shown highly asymmetric periodic variations with a period 0.d0566513(22), full amplitude 0.m218(4) and a very high asymmetry M - m = 0.670(9); a secondary minimum 0.38P after...
