[vsnet-campaign-dn 16846] ASASSN-22oh: WZ Sge star below the period minimum
by Taichi Kato 13 Jan '23

13 Jan '23

ASASSN-22oh: WZ Sge star below the period minimum Josch Hambsch has reported further observations. I obtained a period of 0.05155(8) d and the profile is compatible with that of early superhumps (full amplitude 0.04 mag). More time-resolved observations are requested considering the likely unusual nature (either core-evolved CV or a population II like OV Boo).

PNVJ00215475+5231007: likely WZ Sge star Kiyota-san and Itoh-san have reported observations. 0.04-mag early superhumps with a period of 0.058(1) d were likely present. Since the amplitude was small and the baseline was a few cycles, confirmatory observations are needed.
